Why buy this stuff like this? Why not just get it for less than half the price in the diesel isle at the truck stop?
Here's a locator for DEF. https://www.discoverdef.com/
Wisn there was one close to me. I live on Long Island, NY.

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.

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.

I'm thinking that's an owner's manual deal.

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

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

Not motor oil, this is just some crap that gets sprayed at the beginning of your exhaust to help reduce emissions, I don't think you'll ruin anything but when you run-out your vehicle will no longer restart until you fill the reservoir.

It's simply overregulation at it's finest, just say thank you EPA, whom costs us a few hundred billion a year in regulations and around 9 billion to run.. don't get me wrong some regulation is needed, but we're far from the largest polluter.
Not far at all. US is the top polluter overall and if you account for the US interest manufacturing overseas there is no contest.

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.

100% will work with no issues. DEF is DEF as long as specs are correct, no issues with this brand.

Nope, will not damage filter just like running out of fuel will damage your engine... If you run out of DEF, your truck goes into limp mode until you can refill. 30mph top is top speed then.

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

Cheaper but not always better. My husband topped his tanks on the VNL and not long after started throwing emissions codes, all came back to bad DEF. It cleared up after we drained and refilled with Walmart stuff. Talking with other drivers it seems some places aren't careful and get water in the tanks. Then you have BC and YT, $20/gallon because it's too cold for bulk tanks. Fun times...

It should all be exactly the same - I had no idea what this is or what it's for, so I looked it up on wikipedia: "Diesel exhaust fluid (DEF) is an aqueous urea solution made with 32.5% urea and 67.5% deionized water." Doesn't seem open to any kind of variation between brands. I had assumed this was for 'rolling coal'. What happens if you run out - does it just put out dirtier exhaust, or does it somehow force you to keep it supplied? Amazing tech - good for all of you for cutting pollution.

DEF is injected into your exhaust system after the diesel particulate filter and before the catalytic converter. EPA forces manufacturers to artificially stop startup or force limp mode if you run out. This gives people the impression that it's causing engine damage when they run DEF dry.
