Chevron Techron Concentrate Fuel System Cleaner (20 oz.) $6.50 (reg $13) free pick up ADVANCE AUTO PARTS
 

20oz Chevron Techron Concentrate Fuel System Cleaner $6.50 + Free Store Pickup
 

Advance Auto Parts has 20oz Chevron Techron Concentrate Fuel System Cleaner for $6.50 with free store pickup. Thanks SUCHaDEAL

Nice find. Can be had for even less using Advance's coupon codes. :yummy:

no store near socal 8.66 ship. bummer

pepboys has them for $5 for the 12oz this week I bought 2 the other day

you have to have your card to get the discount

this is a much better deal.

Coupon isn't working. I've noticed this before when Advance puts something half price.

this 20oz bro + extra 33%-40% off with code

Yep....coupons no worky!

Good deal, although I will stick to using SeaFoam.

I use this from time to time. It's pretty powerful. I had a lawnmower one time stuttering and running rough. I put an ounce or so of techron in the tank and within 10 minutes the mower was running great. It does quickly clean deposits.

I am new to car stuff. My car just hit 100k. Never used a product like this. How many bottles will I need and do I need to use ever 3k miles like they say. Thanks for info

You just probably need 1 bottle and every 3k is very excessive. That and if you run BP or Shell gas etc with detergents in it all the time your car is probably fine. I am buying a bottle just because I've never done it in 60k so im going to do it on my car and my girlfriends car with 140k.

how do you use seafoam, I have heard good things about it, and using it also for intake ??? and not just the tank

Check youtube for videos. Its actually pretty fun to do. You'll be biting your nails the first time though. A few people thought my truck was going to blow up. :lol:

Anybody have any "tricks" to get the coupons to work? It acknowledges the coupon when I add it but it isn't taking anything off the price.

And make sure you rev the crap out of the engine and dog it as you blow the seafoam smoke out the tailpipe. So it seems like you're doing something.

oreillyauto had those 12 oz. for $3.99 a little over a week ago.

It actually says use every 3000 on the bottle but I don't use it very often, maybe every six months. I've got two engines over 200,000 and they have never had a professional fuel injection cleaning.

which coupon code exactly? P20? I tried that one and it doesnt take 20% off?

Thanks!

Codes
 

I think their coupon codes are a little smarter than the average bear. Probably programmed not to stack.

While this is no doubt a great price for this stuff, I have used and recommended Lucas Fuel Treatment for years. It can be had for under $10 with coupons for 32 oz, which will treat over 100 gallons of fuel. This Chevron bottle will only treat 20 gallons.

Yes, Seafoam has always ruled this kind of application.

That's nice they are supposed to be BOGO but instead they just give you half off!

I killed my bike using Seafoam. I added 1/4 of the bottle to the 4 gallon tank, and ran the engine. 2 minutes into the run, engine stopped. I could not bring it back to life until I drained the tank and carb bowl and put fresh fuel in it.

Never had a problem like that with Techron, even if I used a bit more than recommended.

5% cashback through Discover

Should be free shipping on orders over $75. It is not like it is going to spoil or go bad. You will eventually use it up. :D

Edit: Just checked, add 12 to cart and you get free shipping.

what are you going to do turn back the clock ;) it all depends how far you have to travel to get it if you really need it !

I only bought it because I believe someone put something in my gas tank and a mechanic said to use this stuff ! I would have changed the filter in my car but the whole tank has to be dropped to get to it so i'm trying this stuff but otherwise I would have done the Sea Foam through the vacum hose and cleaned out the jets :mad:

Thanks; wish i would have seen it earlier in the week before i bought a 6pk through amazon at avg price of $9.

I've always been suspicious of seafoam, but I can't prove it's bad. I just get uneasy when a product says use it in the intake, gas and engine oil. Also, the cheesy name doesn't inspire confidence. And the You Tube videos don't inspire anything but laughter. My favorite is the guy who puts it in the intake and then has his kid (daughter) go behind the car with the camera and he stomps on the engine blowing clouds of smoke all over her. Then he drives away dogging the crap out the engine. Yeah, I'm sure that was good for the kid and the engine. I want to see lab test results on Techron vs. seafoam vs. Lucas.

There's this which implies that both Techron and Seafoam suck for removing fuel deposits.

Thanks OP. I've been waiting for a deal like this to come by since I missed the last one around December 2012. Sad that we can't apply any coupons for this time around.

These were $4 AR for two last summer. If you dont need this now, it may be worth waiting for a sale + rebate

Almost hit the "place order" button :lol:
Thanks for the friendly reminder :wave:

Is this good to use on a 2005 Honda Accord LX 4 Liter Engine? It's got 100k miles. Thanks!

keywords there are "last summer" and "AR"

This thread I read a long time ago basically says techron is one of the few that are safe and not too strong. I can't find another thread that went into more details with more actual testing but it basically confirmed techron is safe as well and theoretically should help clean.

http://www.s2ki.com/s2000/topic/1...they-safe/

I have been using techron cleaner for almost a decade and results are good. I use it every oil change (5k miles) and track my car regularly. I also send my old oil in for testing at a lab every 15k-20k miles and engine wear looks normal. My car has been going over 150k miles strong but I do take care of my car better then average, but I also use it to 100%(track)

iirc If you use Chervon gas, they include some techron, the regular gets a little bit less tho. Kinda pointless to buy these bottles if you use Chevron but it shouldnt hurt as well.

if i had a local advance i would buy a case full
always worked for my family and customers cars

Decent reviews. I'll give it a shot. Thanks OP.

Dont also forget the "if you don't need thi now" keyphrase :)

You shouldn't bother forking out money for this garbage when a acetone mix will do the same exact thing.

However, you should check and remember to top off your blinker fluid reservoirs if you haven't. Advanced Auto has a good deal on blinker fluid currently.

promo codes dont work on this..

Is this the same as ones sold in packs at Costco?

Don't use Seafoam if you want you O2 sensors to not get an oil coating. I know they say it won't hurt them but since SeaFoam is around 30% oil its definitley going to lower their life. Techron additive is a way better cleaner than the simple Naptha and Isopropyl alcohol in seafoam.

Bro, you sure about that? I know you have noticed the ethanol they put in the fuel these days and I must say they can raise H E L L, especially if you leave it there unused for a fair amount of time. Normally that can be rectified by using stabilizer.

Don't use any of these...
 

It's a scam.

Show me any reputable report of where it makes a diff.

Most gasoline has detergent additives in it with all engines pretty much fuel injected.

It's like the 93 octane scam......

I have a LS2 6.0 Corvette motor in my 2006 GTO that asks for Premium.

I run 87 or 89 and the black box adjusts the timing accordingly.

No knocking or detonation problems.....

Oh...get your oil changed every 3000 miles too...NOT

100% snakeoil.

You're an angry elf.

Oh? That's a first. :confused: Last year I stocked up on the 12oz size @ 2/$6 (I think) and was able to use a $20 off $50 coupon code just fine. Oh well, I suppose I'll just have to settle for the $5 & $10 coupons (20%) that come in the mailer.

:shake:

I believe Costco sells this stuff, but not sure the price though.

I'm pretty sure the ones at Costco are not the same


I use it sometimes on 1 of my car but for the others, never used any additives, 200k+ miles and still running strong

Does this thing really works?

As a guy who reads a lot on BITOG and has done a bit of reading online otherwise, I'll say this: Techron is certainly not snake oil. It is one of only a few fuel additives which has PAO inside. One of the GUMOUT's does (the better, FULL system one or whatever), this, and Redline S-1 (if I remember correctly).

The cheap fuel injector cleaners available do very little, this contains a large amount of the additives contained in Chevron fuel. This is something I'd use every 10K-15K, personally. Since my car was bought used with over 100K, I've used stuff like this a few times.

That said, I recommend Autozone's deal when they run it on this. I think it was B1G1 of the smaller bottles (perfect for normal sized fuel tanks) for like $7.

Seafoam is different, it can help do some cleaning in a couple of places but stuff like this with PAO or hardcore stuff like Kreen are what will do the most help for your vehicles.

sure an ecu can retard or advance for lower grade gas
but with that you make less power..

why would you want to make less power?

Hah the first time I used it my whole car was shaking when it was chugging the seafoam, i was freaking out, did it out in middle nowhere so the smoke wouldn't bother people and I could throttle hard without worrying about cops, was scared to even try to start it back up after it died out, helped the car start a bit better though in the long run!
Was it an old bike? it probably had so much crap that got knocked loose from the seafoam it plugged it up. Had that happen to an old lawn mower when using the stuff.
You do realize that ethanol acts as a detergent as well right..? When they first started using it there were issues of it knocking so much of the gunk inside of gas tanks loose(before even starting the engine) that it was just clogging injectors and carbs, which in turn gave itself a bad reputation in its early days. The reason it's bad after a long period of time is because it doesn't displace water as well as gasoline, which is exaggerated if its left for long term, which is where fuel stabilizers come in, to slow down the process.

I guess it all depends on who you ask. I've used it every 3k miles w/ an oil change. Went through about 6 bottles if I remember correctly. Didn't notice any difference. Although I did use the "weaker" cleaner, not the one OP posted. Used it on car that had close to 100k miles if that helps.

Are these things really working? I am not talking about your idea/feeling/impression/judgement, are there any professional research to confirm it is the real deal instead of a marketing scheme? All I can find are opposites:
http://www.importtuner.com/tech/i...ewall.html

I don't disagree with you, but I said it raises hell with your fuel system if you leave it in there for an extended period of time. Leave it in a small engine over the winter months untouched and see how it performs. If it does not happen the first winter, try it again the following winter.....just saying.

Okay...first let me say that I agree with you on detergents in our gas. Most brands of gasoline (yes, I -KNOW- there is a difference in formulas from one brand to the next, hence one brand can be "better" than another) does incorporate detergents into their mix at the pump. That said, the concentration level is much less and the quality/effectiveness of said detergents varies. (Out of all concentrated cleaners on the market, Techron is the only one I buy.)

Now, as to your LS2 Vette engine...so your getting less output (HP) from your engine whenever you use regular gas, as your engine's fuel management computer retards the timing of the engine to avoid it being harmed by premature detonation. What part of that "equation" do you not understand? :rolleyes:

What I understand from what you said...

You went with a high performance sports car to get all cheapo on feeding it a "proper diet". Why bother getting the LS2 engine then? Why bother with a muscle car, period!?! :shake:

Why do you naysayers always come in to these threads to spout your garbage about how ALL (eg; generalizing) those fuel additives do not work, when you are not any more qualified to speak on the particular product at-hand than Joe Schmo? :rolleyes:

I have a 1999 Yamaha YZF-R6 that has a carburetor. Remember those? No fancy fuel management computer anywhere in there to retard the timing to prevent a damn thing. My engine was worked over by some boys out of Ohio that raised its compression to somewhere around 11.5:1 (over 10.0 stock). Were I to try something as stupid as what you've done with your LS2 engine, I'd probably end up breaking my engine within a 100 miles of gassing up. No joke! Not to mention that the bike would run like chit and sound as if its playing back a prerecorded shootout at over 110dB (out my Micron carbon exhaust w/no baffling/spark arrestor), backfiring whenever I throttled it up too quickly.

You sir, should take your GTO and trade it in for a Honda or Toyota. Nah, go with an Acura or Lexus, as that probably would fit the bill for you a bit better. I believe most of their engines pretty much run on regular gas and have compression levels low enough (8.0-9.0) that the grade of your fuel should not make a lick of difference. Then you can go all cheapo on your ride, not worry about its engine performance, and trade it in before you would ever need to even think about fuel additives.

never really understood the purpose of these things. i have 182,300 miles on my Jeep. never used any fuel system cleaner and have never run into problems with clogged fuel injectors, yada-yada.

i feel like if i bought this for $6.50 and poured it into my gas tank - i will have wasted $6.50 and a trip to the store.

perhaps the usefulness of fuel cleaners depends on how prone your specific vehicle's engine is to getting clogged up. then again, here in PA the gasoline is so loaded up with ethanol and cleansing agents (the MPGs i get in this state are considerably worse than other states) that it pretty much eliminates any need for fuel cleaning additives

I throw a bottle of Techron CONCENTRATE every 6,000 mi. It's worth the $13/year even if I'm not 100% sure it's making a difference. I've read enough positive things about the stuff in car forums to keep using it.

Now the use of regular octane fuel in a car that specifies premium is just playing with fire. I had a 2000 Nissan Maxima with about 65,000 mi and I started buying my premium gas from a local gas station that had incredibly low prices. Well after about a month of that, I started noticing my car had less power and started knocking under hard acceleration. I couldn't figure out what was wrong. Tried some fuel additives (not Techron) and it didn't help. After about another month of this I finally caught on and realized the @sshole was selling regular gas as premium - and that's why his prices were so low! :omg:

But by then the damage to my engine was already done. That thing knocked so bad and had lost so much power that I traded it in and bought another car because I just got fed up with it. I should have reported the gas station but I was in the middle of a divorce and didn't have the energy to deal with it at the time.

Maybe some engines are better at managing the lower octane without damage, but car companies specifiy this premium fuel for a reason. It's not like they make extra money by telling you to buy premium octane gas - it's because the car can be damaged without it!

how is this product different from snake oil?
Does this perform better if I pour it into the gas tank

I disagree.. just fgured out that it works better than snake oil, that I know for sure if you pour it into the gas tank

Is this thing necessary? I have never use it.

Just change the spark plug at required manuf interval and its good enough?

IMO Lucas products are the true "snake oils" of additives. Many moons ago upon walking into an R&S Strauss Auto, I saw their "oil stabilizer" demo showing how adding their formula made oil stick to the gears inside the transparent gizmo near the register. The thing is, should you add just about any heavy weight oil to your standard 10W30 or 10W40 you'll witness the same effect. So why buy their "oil stabilizer" for $9.99? Nowadays, I simply steer clear of the brand Lucas like it's Slick50. :D :omg:
True...acetone is the primary cleaning agent in most fuel detergent additives. The problem, for some, is finding high-grade acetone to work as effectively as Techron. ;)

BTW, what the hell is "blinker fluid"? :look:
I agree w/ur assessment on the overall YMMVness. I used to own a 1988 Audi 90 (my 1st car) with a 1.9L straight 4-cylinder. Nice compact luxury car that was great on gas. For whatever reason, the Germans that designed the fuel injection system for its 1.9L engine specified for a required 110psi of pressure to the injectors. :omg:

The car specified "premium fuel only" and I believe it was due to the aforementioned spec above and the fact that the engine had old-fashioned fixed timing. From the finickiness of that Audi's engine, I learned through trial and error that it liked Exxon, Amoco (now BP), and Sunoco. (The entire short list right there, as I had enough of these stations around me in NY not to try them all.) :P It would always ping if I fed it Mobil, Shell, Getty, etc. etc. Back then is around the time Mobil became the first to start heavily marketing their detergent fuels too. The Audi would ping like mad on their stuff though. Go figure.

Seafoam over this any day. Seafoam through the brake booster, in the oil pan before oil change, then the rest in gas tank.

How can I tell the difference between the lighter and heavier versions of Techron?

not necessary, keep up with regular oil change along w/ maintenance, you should be a ok

usually "heavier" is more expensive

Costco has 6 packs of these for $17.99, sometimes there is coupon makes it $10,99 for 6 pack.

Regardless of the price paid for it, all gasoline sold in the U.S. contains the detergents and other ingredients mandated by Federal Law. They are all that motor fuel requires to function properly in modern engines. Adding solvents and other chemicals to the fuel system in hope of treating some vague, supposed fuel-related malfunction is silly at best. "But he told me..." or "I know my car had more power..I just feel it", etc. are just so much self-delusion on which many industries thrive in this Country. I'm not saying that the solvents don't dissolve some compounds that can occur in gasoline held in storage for VERY long periods of time; they do. That's just not the case with cars that are in actual use. I'm old and keep my cars just about forever. I've never used any additives of any sort. I change my oil and filter every 5-6000 miles and have never had an engine wear out, burn oil abnormally or require rebuilding.

Can i use this for my nissan altima 2.5 S... Please let me know..

I think you had other problems w/ your Nissan. Premium unleaded is recommended, not required. I'm sure Nissan has invested enough money on their RD to design cars so that the car will run on any available octane across the US.

They are not the same!

use it

Did you know? You can use old motor oil to fertilize your lawn.

Yes and no. You can still get valve deposits and clogged injectors if you use off brand gas. I wonder about all the pro injector cleaning services for big $ though, I think some of those are questionable. I don't think you would notice a difference unless you had a partially clogged injector though. But maybe down the road your valves would be cleaner. I think fuels are better than the used to be but I still use techron sometimes since I use grocery store gas due to the gift card points program.

I know I've had techron smooth out an idle that wasn't quite smooth. I also think it's more important to run 93 in a car that requires it than to use fuel additives. But if 93 is optional, that's different. The big thing is not to use 93 in a car that calls for 87.

You didn't mention my favorite scam, the nitrogen tire scam.

This is from my past experience ...

If you find your car jerking when you try to ramp up, it might be cause by the transmission oil is old. After I change it, its smooth sailing.

I would have thought spark plug misfiring due to fuel foul and you need to get this cleaner and it is NOT!

this is a waste of money, it is better to buy better gas from chevron or shell which already has this in the fuel. i always use shell, and chevron when shell isn't around. i never had a problem. all i do is change my oil, filter, spark plugs, and air filter. i do about 20k a year minimum. i usually pump gas twice a week.
dont buy garbage gas from a mom and pop shop, discount chain (wal-mart, sams club, bj's, costco, etc...) saving $0.05 per gallon really worth it? no it's not, you only save $0.50 - $1.00 for a full tank. with gas costing 3.70 or more, it doesn't make sense. just fill up with higher quality gas and don't buy this product. you would have to fill up 130 gallons for this to be free using the money you saved using inferior cheap gas. $6.50 / $0.05 = 130 gallons

Thank you for repeating what I just said with different wording.

Yes. This is the best cleaner out there. 98% of all other cleaners are junk. I would do this every 20k or so.

It's not easier to buy gas from Chevron if you are using Kroger's gift card program.

Or if there are no Chevron stations (even Shell is few and far between here--and more expensive usually)

Anybody had any luck stacking coupons? Read through the thread and found little evidence of it. Also, I put $100 of items in cart and added "$40 off $100 or more via code "TRT41" and it did not work, is this still valid?

I only use Chevron gas. But I still use this Techron product once every 6 months (just make sure to time it right, so you can change your car oil immediately after finish the full tank with this Techron bottle).

$6.5 is a waste of $$ indeed, but it's a LOT less than visiting a shop for a fuel injector service. One thing I notice after utilizing this Techron in my cars is that the engines run smoother, quicker acceleration during freeway entrances and the gas mileage improves (not much but I can't complain when the gas price is outrageous high ATM)

BTW, if you have to consider whether $13/year expense is a "waste" or not for your car, and you're on SD, your head needs to be examine! You bought and buy and will "waste" so much $$$ here on SD from impulse buying, a LOT more than that miniscule $13!

Coupons will not work with this deal.

Just picked mines up... they gave me two instead of one... is it buy one get one free??

A lot of things are a waste of money, buying a new car is almost always a waste of money for example. I could name 15 things right now that many people waste their money on and a lot more than $6.50. I'm always going to have at least one bottle of techron for the lawnmower at the very least. Saves me taking apart the carb.

No, it's just your lucky day. They got confused with the online ordering. My store used to do stuff like that too but now they got it down.

It is in the store. I think store prices is $13, then BOGO. Online they just halve the price for each item. Sounds like you did well

got an old 1980 honda cb750C that i have not run in over 5 yrs. the oil and gas has been in the tank since then. would this be ok to put a drop of this on the tank and take it our for drive on the parkway before i change the oil and add new gas?

I got a BOGO offer in post a couple of days with a bunch of other offers. Ordered one online and picked up - when I showed the booklet with the offer - they gave me one free...

so its 3.25 per bottle.. not bad at all.. :)

If I get the gas from chervon regularlly, do I still need this product?

I always thought using 93 would give me better highway MPG. I have 2002 honda accord with 200k miles. Do i need to continue using 93 to give me better engine lub and mileage? or 87 is enough?
Thanks..

from car noob

These threads are always amusing. Especially the people who ask perfect strangers for advice and get 10 different answers. Like there's some all-knowing oracle hanging on an Internet forum.

I think you wasted alot of money so far. You should compare mileages you traveled with full tank of premium and regular gas

:lol: Funny because its true.

So should I just buy Chevron gas every once in a while to clean the fuel filter/injector? It would probably be cheaper than buying a couple bottles of this stuff and using it every 10k miles.

I highly suspect that if your car is well serviced and running properly all this stuff (and all of the other fuel additive snake oils out there) is going to do is "possibly" make you feel better and leave a hole in your wallet.

You should look up what "octane booster" really does to your performance, according to the UK TV car show "5th Gear" - of course those not testing their engines in a lab will swear blind they get more performance ;)

How to use it?

Not sure if you are being serious or sarcastic...

ROFL.. how is 93 a scam when you're forcing your ECU to retard your timing? Do you understand what you are doing?

autozone has this 2 fer 1 sale all the time for $6.50 sumptin

It is a shame you didn't do anything towards the gas station that was peddling off regular as premium. Fines are seriously steep for any station caught selling gas that doesn't meet the minimum octane ratings on their respective pumps. (Stations also get fined should a franchise inspector find that the gas being sold is not the proper formula that conforms to the brand, as that is indicative that the station (owner) is getting their gasoline from sources other than the franchiser.)

You also could have sued the station owner for all repair bills related to restoring your car's performance back to its previous state. You probably needed a professional injector cleaning, new fuel filter, new spark plugs, new o2 sensors, new catalytic converter(s), etc. You could even have added a rental car to the bill, since your car would have had to spend some time in the shop for repairs.

Anyway, heard you about the divorce and all. Just saying, small claims court usually covers suits up to $5K, and judges WILL award a well documented consumer with proper evidence. Since it sounds as if the station (owner) kept pulling the same scam, it would have been easy for you to acquire a sample to send to a pro lab to have it analyzed, etc.

That is why it is so important to save your receipts, especially when it comes to your car. I save everything and I mean EVERYTHING. Guess now it is just out of habit, as I service my own car whenever I can, which so far has been 100% of the time. :)

Man, you were supposed to drain at least the gas tank completely if you were going to let your bike sit that long. :eek: Hope you are in Florida, b/c winters can wreak havoc on a moto's carbs....

If I were you, I'd:

1. siphon out that old gas from the tank and replace with 1 gal premium and 1-2 ounces of Techron concentrate. (That old fuel is crap now, dispose of it.)
2. drain about 4 ounces of oil from your engine by removing the oil cap w/dipstick and tilting your bike on its side (over a canister of some type, of course).
3. replacing those 4 ounces of oil with Seafoam and running your engine at no throttle w/choke half way until warmed up.
4. drain old oil and change w/fresh oil/filter.
5. fill gas tank w/premium and add appropriate amount of Techron/gal.
6. test your motorcycle's throttle response.

If your engine is not running properly, you will need to have its carbs cleaned/degunked. You can try watching some YouTube vid tutorials, but it sounds like it might be best if you left it to a professional as it can be tricky if you don't have the right tools, experience, etc.

It says on the bottle how to use it. If you don't know how to read, how did you find this thread, and how do yo expect to read a reply?

If that is the case, the bottle says that the driver has to drink it and then immediately operate the vehicle at a high rate of speed. The cleaner, through diffusion will clean the inside of the engine, and if driver does not pass out/die then he/she is fit to operate the vehicle with the newly acquired massive horsepower gains. :D

I hope you disclosed that you were trading in a bum vehicle. It is not like you stuck a dealership with it. They don't keep it, they sell them, most of the time without knowing that there may be an issue with the vehicle.

So, now the next owner is stuck with it, when it could have been fixed perfectly by you pursuing the gas station owner.

That is exactly why I always tell people not to buy used cars. People usually don't sell perfectly running vehicles. they keep them, until there is a problem that they don't want to fix and just want to stick someone else with a bill.

"It says on the bottle." You serious? If i have one in hand i wouldnt be asking. People like you make this forum hostile.

Get used to it. There's a how-to-use video on the product page

weird,they have me 2 also. I saw someone else post the same thing

See if hes like you there wouldnt be a problem. And his joke isn't funny at all, which makes it even more worthless. By the way that was a video of comparison.

comparison or not, you see the guy pouring it into the gas tank right?

Yea but hes in the shop. I don't know if we should just pour in there and then drive. i thought he would run it and empty it. who knows. But I checked out a youtube vid after then I know.

Thank you.

This is the one for 3000 miles, is this the weaker version people were saying is not too usefull? or is this the "good" concentrated one that should be used sparingly?

Another thing, if you're looking to get this at your local Advanced Auto and don't feel like purchasing online and printing out a piece of paper for in store pickup they will NOT match the price of a single bottle there for some stupid reason. In store however they're doing a buy one get one free on it so you gotta get 2 to get 1 at that price. When I was in store though I realized it said 3k miles on it and I wanted to double check back here to make sure it's the right one that's worthwhile to get, plus I only want one.

Lol like dealerships actually care about anything else besides making a buck? Going to a dealership and not having your car properly checked out is like going to prison and just bending over all day.

it's the Techron Concentrate

Perhaps you got a defective bottle. This is what mine says.

I picked mine up yesterday, and they are exactly the same ones as in the OP link [advanceautoparts.com]. It says it is "Techron Concentrate Plus" with a thin cardboard wrap around flag on them.

Maybe some stores are giving people ProGard Fuel Injector cleaner [advanceautoparts.com], instead? But, that item is not what is discussed here. That one is less potent and can be used every 1,000 miles, per the verbiage on the container.

How old is the bottle that says 20,000 miles? I haven't seen those in over 10 years. They used to sell those retail, but stopped, probably because of the concerns you raised. I believe the only way you can get them now is if you have a repair shop. And it may only be used if you have a "fuel injector" machine that feeds it into the injectors directly, not through the fuel pump.

All these "magical" fuel injector cleaners are a blend of xylene, toluene, and probably hexane or pentane, which are really strong solvents and will dissolve most polymeric plastics, which are now commonly used in the fuel supply systems.

The older ones may have had tetrahydrofuran which will "digest" pretty much any polymeric plastics.

I've got an old Toyota that won't die, but does have a persistent P0420 check engine code which points to the converter.

I've used this stuff from Costco on the highway annually, just before State inspection, to clear the code. Full jug to a half tank gas (9 gallons) worked and been doing the same since annually.

I don't know what this snake oil is, but it does do something.

Have noticed the light comes back on after driving through slush or a flood... seems anything that rapidly cools the converter throws the code and it sticks.

Just ordered a bottle. Glad the deal is still live. Thanks OP!
