why does my vauxhall combo van not idle properley on heated veggie oil?

Answer 1

i have no experience with the fuel , but how well is it filtered before it hits your tank ? i would suspect that passing it through a 10 micron filter would help, does your van have a water separator on the fuel line ? how is its fuel filter ? perhaps the fuel you are using does not have the same heat value as diesel and you need to increase the fuel pressure or the injector opening time ( whichever adjustment you can make , we don't have these in Canada ) good luck , as Kermit the frog sang ,it's not easy being green.

Answer 2

why use veggie oil and not the normal stuff?
