How to make Jeep Wrangler Run on Vegetable oil?

I'm really interested in doing this. I have seen others with lifted vehicles, Jeeps included, running on vegetable oil. I have even seen some old Mercedez-Benz cars with stickers claiming they run on vegetable oil.

So, does anyone have an idea as to how to begin this modification? Gas sucks!

Yeah good luck on getting a gas engine to run on WVO (waste vegetable oil). You need a diesel engine for that. This involves a swap of some kind and do not expect it to be cheap. The money you spend probably wont be recovered on the fuel savings.

Gas engines won't run on oil. They will run on propane though

being that your in california, and an enhanced smog area i would check with your local smog laws b4 starting a diesel swap or propane setup. my buddy has a 4cyl diesel in his land cruizer and he loves it now he put a turbo on it. his is pre 1976 so anything goes. i wish they made cj7's b4 1976 ,i would have bought one and not delt with every 2 years and drop any motor you want in. pre 76 jeeps are just to small

You need to do a diesel swap first, between 10-$18,000 usually. Then you do a greasecar conversion, basically, it just adds a new tank that heats the oil then you car runs off both diesel and vegetable oil. If your Wrangler is already a diesel then the grease upgrade is only about $1,000.
This certainly isn't an upgrade to save $$$$ when you take into account that it can cost $20,000. If your car is already diesel then it will save money, because you can get the oil for free from restaurants and recoup the costs for the grease upgrade in a few months and after that drive for free (except for starting/turning off the engine, which has to be done with diesel).

I installed a propane setup in a truck I had many years ago. I could switch from propane to gas with the flick of a finger.

Propane gets about 10% less miles to the gallon, The good part about propane is that your oil never gets dirty. No carbon build up. Propane runs very clean.
