I should say *used* vegetable oil aka WVO, not SVO. Not that I would use
it either way...

It's got lots of impurities that can act in unpredictable ways @ 22kpsi.

Quite a bit different than the 50psi fuel systems in a 80's vintage
Mercedes.

'sidies, these concerns are separate from what 100% bio does to some
engines (clogs injectors in Caterpillar diesels, reportedly turns
injectors in Cummins diesels into blowtorches, fuel pump damage), even
when the fuel is properly made.
