Chevron Techron Complete Fuel System Cleaner is a low cost fuel system treatment that is valued for preventative maintenance and occasional cleaning. The PEA formula is credited with smoothing engine operation, helping fuel gauge sending unit contacts, and improving injector spray patterns, with some using it every 6 to 7 thousand miles or a few times a year. The main caveats are that it is not a miracle fix for heavy deposits, and the NAPA coupon can be hard to use because it requires a 125 dollar cart and may not apply to sale or clearance pricing. Store stock and pickup charges also appear inconsistent.

  • The cleaner can make an EV run much smoother after use.

  • The cleaner may help prevent early oily or sticky deposits in fuel systems.

  • The cleaner can be used as preventative maintenance after about 6-7k miles.

  • The cleaner may clean fuel gauge sending unit contacts when used properly.

  • Buy online pickup orders can place a temporary card hold that may not reverse quickly after pickup.

  • The 20% off code may apply only to NAPA retail price and exclude sale or clearance items.

  • The 20% off coupon may not apply to this item even after adding multiple bottles to the cart.

  • The coupon may require $125 or more in cart totals to be eligible.

they charged my card a higher amount than my order total. here's what customer service said when I contacted them: Hello,

Thank you for reaching out. For Buy online pickup in store orders, sales tax is estimated based on pick-up store location and may not reflect the actual sales tax amount due at time of pickup. NAPA Online will request for an additional 5% on customer's payment method in case of local tax variation. This is just a hold and will be reversed once the order is picked up in store. However the refund will still depend as to how fast your bank can process the refund but typically appear within 3-5 business days.

Should you have further questions, please call our customer service hotline at 1-800-538-6272 Mon-Fri 8AM-9PM EST; Sat-Sun 8AM-5PM EST for further assistance.
So has it been 3-5 business days? Give them a chance to process it. I think you are overreacting right now. if it doesn't show within a week, dispute the overcharge. I agree they shouldn't do that, it's BS, but opening a dispute for $5 or whatever the over amount is without waiting is a huge waste of your time.

This stuff works and has been proven to do so, but not really as instructed. I use it on an almost empty tank to get the highest concentration. It's more of a preventative maintenance product as its pretty hard to clean built-in deposits but great to prevent the deposits when they just start as an oily/sticky substance.

Probably true, but I run this after 6 - 7k, just incase some build up may still occur. It's cheap when you're only using it 2/3 times a year. For people who don't use TT gas, it's essential, and needed more often. I'm buying this bc of the super low price, but I like Red Line S1 better for it's higher PEA content.

Yeah, I was also charged a few bucks extra. Thanks for the explanation. Hopefully it will just auto drop off once the sell is completed.

Bought 6. Apparently I got $5 off for signing up for NAPA Rewards.

EDIT: May have spoken too fast. The order shows $5 off, but they charged the full amount, and did not give me the $5 off.

I am the head mechanic at our shop. And I see products with PEA work. I see it first hand often with cleaning fuel gauge sensor aka fuel sending unit. It will clean the contacts on the rheostat aka variable resistor. Most times its our go to for fuel gauge not reading right. I also camera borescope engines for carbon. and look at the spray patterns on fuel injectors. So I wouldn't be so bold as to say its worthless. Not sure what miracles you may be expecting for a few dollars. But it does do its job, cheaply. There is next to no harm in trying it besides a few dollars lighter in your wallet. If you do it properly and treat 2 to 3 tanks back2back and see zero results then maybe your machine didn't even need it. Doesn't mean PEA doesn't work though. It does do its job

The only reason I am using this is because of fuel gauge issues...

I stopped by 2 NAPA's on Sunday that I happened to be passing by and neither had it in stock, despite online indicating both stores had it in stock.

Obviously you don't research. Techron has never been snake oil. Research what PEA (Poly Ether Amine) is. Then you can make educated posts that the educated will care to read.
Completely agree. you must be a bobtheoil member too. This is far from snake oil. You want snake oil go buy gum out brand products
