It's pretty much become standard with most diesel manufacturers now to officially OK B2, B5 and B20 for the most part. A few of the farm equipment factories are shipping every machine out with B2 as standard.

They'll jump onboard for higher BD percents as testing continues...I'm sure. There's just not enough data out there yet for them to do it now, so they're covering the butts to be sure their safe. Business is business.

There's a good list of companies and their warranty policies here...

WOOPS - Glad you mentioned that - in the same article they are shipping all diesels with B5

 

Yeah, everyone except John Deere, who will void the warranty if ANY percentage at all is used.

 

Not true Andy...John Deere also allows use of BD. Their statement can be found here...
