Thats been around now for awhile. Always a good review and reminder that are current fuel is crappier. I wish nationwide that all diesel sold was mixed with B5, because according to that study, that lubricates the best.

 

I agree, the article has been posted on most diesel forums for awile now. Some states require a mixture of bio in diesel fuel, but in my state (Pa.) most stations don't even post the cetane rating on the pumps. There should be federal standards on cetane ratings just like there is for octane numbers.
