Whether your motivation is the environment, the economy, independence, or you simply despise the oil companies, converting your diesel vehicle to run on waste vegetable oil (WVO) can truly be a rewarding experience. (You can get WVO free from restaurants, preferably higher end. Luckily for me, my brother-in-law is a head chef, and he has access to WVO.)
Greasecar sells complete conversion kits for diesel Volkswagen, Volvo, BMW, Mercedes-Benz, and Peugeot cars, and Ford, GM, Dodge, and Isuzu vans and trucks. I could not be more pleased with the results of converting my 2004 Jetta TDI Wagon to run on WVO. The kit supplies all necessary components, which upon installation revealed high quality and excellent fit and features. Written instructions and a professional installation CD made the project a complete success for this weekend mechanic.
The neat part about the kit is that it doesn’t compromise the car’s original diesel system. You start the car on diesel and, once up to temperature, you transition to WVO either manually or automatically. Prior to shutdown, a simple button on the onboard controller initiates back-flushing of the WVO lines with diesel fuel so they won’t get clogged with WVO when the car cools.
Once installed, the operation is incredibly simple. The true reward is driving a few hundred miles down the interstate and not seeing your fuel gauge move … wow!
