The guy at the stations full of C**p. The B20 is for bio diesel, I have run it in an old 7.3 power stroke. I avoid it because of the loss of mileage.


My 2018 Ram Cummins book says no more than 5%. B20 requires an additional optional feature(s) that my Cummins is not equipped with.


The Ram manual is not too clear...but check on the Cummins website...you are B20 approved...also, you will see if you read "between the lines" in the ram manual.
