Rich,I mean, i know guys use it, it just never will. It works just fine if it's not your personnel vehicle and it's a company truck, but i prefer to put the best quality in mine. I will never buy the stuff sitting outside in front of a gas station, not in a climate controlled environment. Def is temperature sensitive, to hot or to cold is highly not recommended. The stuff at the truck stops at the fuel isle that you actually pump into your truck, I know nothing about it ( brand, quality, if the tanks are contaminated, etc). When I was In the commercial lob , they used cheap low grade def in the barrel and I've seen the aftermath of cheap fuel and def on a regen system and the tens of thousands spent trying to fix them and never being able to figure it out. I'll stick with my mopar 2.5 gal jug for $28. You get what you put in. With my accessories, ill have 90k Into this thing. There won't be any PEAK brand for me. Now that you got the good out of me. Whatever you do, please don't bring up regen. I'll stroke out. Everybody has there own analogies and opinions and I have mine, some conversation topics I can't keep my mouth shut on
I have no dog in this fight but I would like to comment.
I've always thought that DEF is DEF. If it meets the DEF specs it doesn't make any difference in brand or price.
I mentioned that once to my Service Manager. He is my friend, I respect his knowledge and he has no reason to give me a sales pitch. That said, he feels exactly like you. He was quick to espouse that there are big differences in DEF and that Mopar is the best by far.
