Just fueled up last night and noticed that my local Flying J is now selling blended biodiesel instead of straight petro based diesel that my truck has lived on since new. The sticker bothers me though, it notes that the blend may be between 5 and 20%. Not very accurate, are we?
The 5. 9 is OK'd by cummins up to B20, correct? How much crap is this new (to me) blend going to clean out of my fuel system and how often should I change my fuel filters during the intital few tankfuls?
