If you could keep it liquid.

fuel warmer? or not 100% cocoa butter I presume. maybe add some jojoba or another liquid oil to the mix
cocoa butter melting point is about 93 degrees
I prefer the smell of Dunkin donuts fryer oil.

You can't run WVO or B100 in new diesels that come with DPF .
The current breed of DPFs is actually blocking the renewable fuels option on diesels.

Not that I advocate burning vegetable oil at all in modern diesels (I don't), but it's not the DPF that is the problem, it's the wasteful way in which they burn out the DPF to keep it clear. There would be no issue with biofuels at all if the diesel manufacturer installed a low pressure fuel injector into the DPF itself to burn it off instead of injecting fuel into the cylinders, post ignition, allowing liquid fuel into the engine oil.

Most manufacturers have now stepped up to B20. Also many are starting to use an external injector due to oil dilution issues, it just wasn't apparent as a problem in 2008.

Yeah, I didn't mean straight cocoa butter, just enough to make the exhaust smell like chocolate :-) |

It's a point of discussion on biodiesel boards, the different consistency of the biodiesel causing the extra squirt to stick to the cylinders and wash into the oil instead of going into the DPF as regular diesel do. And there's no quick fix to this.

Hopefully they all follow suit. |

Which manufacturer uses an extra injector in the exhaust to regenerate the DPF ?

Sure, but as far as I know, all current production DPFs use in-cylinder post-injection - effectively ruling out high biodiesel % in the fuel.
