BIO or non BIO fuel ?
Any different mpg or performance?
Forum Discussion
If I had a choice at a station, I would always buy straight diesel, even if the bio was slightly cheaper. The bio does have less BTU's so there is some mpg loss. My 2005 ISL said max B5 bio on the fuel door, I believe my 2014 450 ISL says max B20 bio is acceptable.
I think what happens with many is that some stations you get bio and some you get straight diesel. With a 100 or 150 gallon fuel tank, one is always diluting the other, so you typically don't see big swings in mileage.
