Has anyone else ran this stuff I love it but hear nothing but negatives on it, but from people who have never ran only heard through a friend of a friends crap. I have ran it for years in semi's and now in my w250 since we finally got a station that sells it. I am alone in running this I get better mileage and smoother running engine!

 

I won't run it in a DPF diesel engine

 

Why not? The DPF equipped trucks have a higher tolerance for warranty. For instance, 6.0 and 6.4 powerstrokes are only warrantied up to B5, but all the 2011 trucks are warrantied for B20...

I probably wouldn't run B100 in it though. B20 shouldn't be an issue. Just make sure you're buying from a reputable place.

 

I only fill up with ULSD, while you can add B5 to the 6.4, I rather not

 

I've ran both B5 and B20 purchased from pumps owned by reputable suppliers. The performance was good. Quieterengine operation and less smoke. The B20 seemed to collect water more easily. (I've heard biodiesel is known for this). Ran a steady diet of it for over a year. I plan to upgrade my fuel water seperator before running it again though. The water issue made me nervous.
