Really?...I always thought that bio had a lower btu rating, correct me if im wrong but if the cetane rating is higher than it would yield better fuel mileage...right?

if that was the case with those numbers I would expect to see higher mileag with b-99....

I used to burn bio in my 6.0 , b-5 all winter and b-20 the rest of the year...I have heard that bio in the 6.4 is a no-no? even though the manual says up to b-5?
