Used this because I had an error code on my 2020 GMC Denali diesel. The dealer tried telling me it was a $1200 issue but when I used this on my own, it cleared out the error code.

Good product but too expensive.

OK

Probably best multipurpose diesel additive I’ve used. Highly effective in categories necessary in a diesel additive, it’s a well rounded additive that does it all. I’ve used this for a while in all sort of diesel engines with good results and longevity. This size is also a win, smaller bottles of EDT seem to always leak but these larger bottles have an effective cap, better off buying this size.

I recently used this in my Mercedes Sprinter van for a 3000 mile trip. Added to every fuel up. It increased 2 to 3 miles per gallon. I would have never believed it. I'm not sure it made it run any differently to notice but it definitely increased mileage. Very pleased with it and I will continue to use it.
