B20 or B2?
 

My local source for biodiesel has B20 and B2. Whats the difference and which would be better for my 6.0L? Or is there no real difference.

The number after the B is the percent of biodiesel, the higher the number the smoother the engine's run. I am using B-80 this winter, but will switch to B-100 in march.FABMANDELUX.:-X25 :-fire

Thanks, that's what I thought but it seemed like too simple of an answer.

Fab is right. I run B100 year round here in PHX. depending on where you live or travel too blending is good in winter to help keep fuel from clouding/gelling. Typically B80 blend is good.

Just remember when using the biodiesel. The ford stand is B5 max for warranty purposes. The fuel must be a ASTM D6751 which is the biodiesel fuel standard.
