A few questions (Engine swapping) (vege oil)

[way2slo]

Hello all I have a few questions about a my work van I believe its on a 2005 Express body (dually) with a service body on it. I like the truck alot for service but I hate the gas mileage 8-10 mpg we are going to buy a 4 door Pickup if i have to put a service body on it but I wan the Duramax diesel. Is there a way to put a diesel in that truck or is just as easy to buy a new one? We will be converting the new truck, or engine to run off of used Peanut oil (vegetable) In is a easy change out? Or is there a conversion for it? Thanks a in advance for any info that will help!

 

Heres a Pic of my truck now! Ill also post up a Picture of my Dads ugly work truck which is running off of vegetable oil.

Not everyone has the answer for every question here. I will say that posting a follow-up to your original post like you did will probably guarantee that you don't get any helpful replies.
