Converting to veggie oil

Admittedly, it may seem daunting to consider converting your vehicle to run on veg oil. Understandable.

It's not as difficult as it seems.

Popular kits make it easier to make the switch. Basically, what you're doing is installing a system to heat and filter the oil.

This is the oil filter. You can just see the coil of the heater element on the inside of the canister. The oil is heated back in the trunk using radiator water and then goes up to the engine. It's heated again there and filtered before it goes into the engine.
