The majority of diesels can handle B99 that is made well - the fear is well, inferior fuel and that a certain number of trucks don't like the Bio's.


The majority of OEM's are just beginning to test their diesel engines on bio. The issues I mentioned were uncovered by that testing, but it's still preliminary. We really don't know what the consequences may be for long term use.

A few SAE papers I've read indicate there's no significant difference in lubricity between refined diesel oil and those with bio content.
