My wife filled up our liberty CRD with a full tank of b99 last week. I think she paid about 3.05 per gallon... I was a little worried about an entire tank full of the stuff, but I figured what the hell? I took it for a spin over the weekend and didn't really notice any difference in the way it drives. The engine seems as happy as ever. It doesn't even smell like french fries. Has anyone else been running b99 in theirs?
