The dealer that was working on my 2005 CRD until about 3 weeks ago had extensive discussions with DC regarding my use of biodiesel, and the Word From God is that 5% remains the maximum approved. Admit to use of more as I did, and DC puts your engine on a watch list: ie, they didn't void my warranty, but they are deeply concerned and have their finger on the trigger.
Exactly. If it comes up, always say "5%" no matter what.

Remember though - this cannot be said enough -
NO VEHICLE MANUFACTURER WARRANTS *ANY* FUEL CAUSED PROBLEMS.
Whether that fuel is diesel no. 2, gasoline, biodiesel, ethanol, or any thing else. IF FUEL BREAKS YOUR VEHICLE, ANY VEHICLE - IT IS NOT WARRANTED.
This has *nothing* to do with biodiesel. It is simply *convenient* for them to point to biodiesel - but the responsibility is on YOU (us!) to make sure that the quality of fuel you put in your vehicle is good... I have seen injector pumps blown out from water in regular diesel from a regular fueling station... Biodiesel is nothing new - just be sure you are getting good biodiesel from good places that store it in good containers and transport it in good containers.

And Reggie, DON'T BUY BIODIESEL FROM PALM OIL! While it is true that oil palms are among the most efficient species one might grow for oil production, vast tracts of the rainforests of central and south america as well as Indonesia are being burned off to plant oil palms, transforming that aspect of the biofuels program from an environmental plus to a big minus. Into the bargain, the cloud point of palm oil biodiesel is close to 60 degrees F, making it marginally useful north of Atlanta for most of the year.
Throw in the fact that it does nothing to promote the financial health of anybody in the US, as we can't grow oil palms here, and there is no earthly reason to import it, save perhaps the capacity of a handful of folks to make money selling it. Let 'em know you aren't interested in merely lining their pockets instead of the arabs. DECLINE THE PURCHASE OF PALM OIL BIODIESEL!
Tell 'em you only want biodiesel from US crops, and drive away from the pump. It's the only way we can stop this bit of sillyness.
WHAT HE SAID!
YES YES YES!
Do not EVER buy or use Palm based biodiesel. Not only is it potentially worse for your engine - but it defeats the whole point of using biodiesel.
It doesn't help the US economy. And when you cut down RAINFORESTS to grow palm oil - it doesn't help with global warming either...
I am even pushing for legislation that would either restrict or tax heavily biofuels from non US sources for US sale. (Obviously our international members can have their governments do the same if they desire...)
