Anyone know what Ford is saying from the factory on bio fuel in the 6.4's???

I believe its B5 (5% biodiesel) as a max, but I'm going from memory.

This owner training video will tell you all you need to know about the new 6.4L powerstroke diesel.

Got a new 6.4 at work the manuel says no more than 5% bio.

Using the 5% bio won't void the ford warranty, ( or anyone elses ) but any failures stemming from it's use wouldn't be covered.
of course, warrantys don't cover failures resulting from the use of any fuel,

Here is a neat link on ford's concerns about biodiesel over 5%

Hmmm injectors and pumps might be the down fall there I or so I ma lead to belive. Of course with all the new 6.4 wowes that are coming out I hope that Ford pulls out of its slump and the 6.7 is a winner.
