Thank you for using this.
I'm surprised the regulation hasn't been rolled back.
We have to breathe this soup we live in, you know.

You can just pee in the tank instead. Just don't eat any asparagus beforehand because your exhaust might smell. I plumbed mine to a funnel next to the drivers seat.

I use it in my 2015 passat TDI, usually last until the next oil change, more likely a little more but that's when I put another bottle in
My 2013 passat has 170,000 miles, all def is the same as long as its fresh it'll be fine.... our truck fleet keep s a 250 gal container at all times but there is no reason to pay extra from ace when you can get it $2cs cheaper at walmart.

The system is tied into the electronics on newer Diesel engines. When the computer reports a problem with the urea system it can shut your engine performance down to like 10%. A friend found this out in his brand new RV the hard way.
For passenger automobiles, when DEF runs out, the car won't start. They won't legally be emissions legal.

At a low level, the car will give you mileage count down ticker.

Def isn't engine oil lol.

Now who can assure me this will work in a 2015 Jetta TDI ? I am almost out of def and don't want to give the dealership any reason to F with me and my warranty.

100% will work with no issues. DEF is DEF as long as specs are correct, no issues with this brand.
The comment below is the answer. DEF specs are industry regulated. There's only 1 way of making DEF and all DEF has the same chemical make up. VW will never be able to test whether you used dealer DEF or truck stop DEF.

DEF is tested, regulated, and certified by the API (American Petroleum Institute). As long as the certification is printed on the packaging, you will be getting the genuine article. For more info: https://www.api.org/products-and-...aust-fluid

Facts. A lot of folks might not be aware truck stops sell bulk DEF

While it isn't this brand you can get DEF fluid at Rural King stores for a better price if you have one close. I think I got 2 of the 2.5 gallon jugs for $9.99 awhile back. They list a 5 gallon bucket on there website for $9.91. See link below. I use the stuff in my 2017 F350 truck and have had no complaints other then having all the emissions stuff on the truck.

I'm a truck driver and can tell you that ALL DEF IS THE SAME so you might as well go with the cheaper stuff. But if you have the chance to get it at a truck stop from the diesel lanes then it'll be much cheaper
The only consideration for us German car diesel owners on whether you should buy Peak vs buying it at truck stops is how you fill DEF into the car. I own an X5. I know for a fact that all BMWs and I believe all passenger MB and VW cars fill via a Kruse engagement setup. Google "Kruse bottle". That's a special filler neck on the bottle that is designed on German passenger diesel cars to make it foolproof and spill proof for owners to refill themselves. It's also designed as a single use bottle to avoid contamination. Unfortunately, it comes at a huge cost. And the bottle design is a patented design and has a monopoly on selling it at dealerships.

The cheapest way of doing it is buying 1 Kruse bottle at your dealership, use it, and then snip the lock off the filler neck and dump the bulk DEF into the bottle. For my X5, I have to refill the Kruse bottle about 4 times to fill the passive and active tanks.

Because transferring DEF from gallon jugs are messy, and because you want to avoid contamination, you'll pour directly from bulk jugs into the Kruse bottle, so you'll want a bulk jug with a spout that is easy to use. When I used Peak, it was a reasonably clean transfer. The jug wasn't too heavy and I didn't spill any of it. If you buy the 5-gallon jugs, good luck transferring it to your Kruse without spilling it. If you're putting the truck stop nozzle into your bottle, good luck managing the flow into a 2L bottle, if it'll even fit.

:
Also even if you imply China pollutes more and you neglect the fact that US and EU consumes the biggest % of Chinese production, adjusted per capita, US emissions are more than 3x that of China.
So it's the fault of the consumer, and not the poorly regulated producer who uses their shoddy environmental standards to undercut the world's production costs?

I do thank the EPA. It's the reason we don't have lead in gasoline anymore. Also bad. Those a-holes with "Roll Coal" decals all need their heads pulled out. Also, buying a diesel truck to roll around town in... Maximum white trash factor. There for towing, not showing.

Dumping (expensive) unburned diesel out of a Folgers can-sized exhaust tip is about the dumbest thing I see on the roads.

So, yeah, bring on the DEF. also bring on nation-wide emissions testing for vehicles that don't have to list their EPA fuel economy ratings, like 3/4 ton and larger trucks.

We're really dumb as a nation on unnecessary fuel consumption, and I'm not even a tree-hugger type. It's just wasteful. SMH
You do realize new diesels are less efficient than old and therefore need more fuel to stay clean? They are so expensive and unreliable that all of the big 3 are going back to big block gas engines they must be better for the environment than a non emissions diesel getting 20+ mpg in a 3/4 to 1 ton truck. For what it's worth the black 'coal' is just unburnt fuel that falls to the ground doesn't do anything bad but annoy anyone. I hate those holes they runied diesel for the rest of us.

So why do we have the Titan XD, 2020 Ecodiesels, and the new Ford Diesel?

Because 'diesel' is the buzz word these days they also lead marketing because they produce large numbers at the cost of longevity. Look at any utility or large fleet company how many modern diesels do they have? Why is everyone now offering more gas options than diesel ones?

If you run the numbers a modern diesel just doesn't make sense unless you're running loaded over 15k all of the time. I wish it was different but it isn't. While the new stuff is impressive I'll take my old engine any day for simplicity ease and cheapness of service and plentiful support.

Wally World is 7.99 for 2.5 gallons if you don't mind going in there. I use a gallon in my 2015 Passat between services.
