With a few modifications, you can run a diesel vehicle on vegetable oil to power your car or truck. People across the country are using conversion kits to retrofit their vehicles. Others are taking a do-it-yourself approach. Some burn free waste vegetable oil from local restaurants; others burn clean straight vegetable oil. But there’s a catch: Technically, it may not be legal.

Running a truck on vegetable oil does not decrease power significantly. This veggie oil powered Ford F250 easily handles a camper trailer.

In addition to making engine modifications, you must filter waste vegetable oil prior to burning it in your vehicle.
