As the run down, beat up, diesel auto pulled into a parking spot in front of our health store I could see what looked like advertising in the window. Thinking it was a "For Sale" sign I was surprised to see "This VW diesel runs on used veggie oil". Okay, now I really had my interest piqued, but the owner was hesitant to give many details other than to say he was recycling vegetable oil from restaurant deep fryers.
The wonders of the internet made it easy for me to satisfy my curiosity and delve into the subject of alternative fuel sources. Trips to the library and a purchase of one particular book called "From the Fryer to the Fuel Tank" and I was on my way. I invested in all the hose and fuel lines with electrical fuel selector valves.
Heat is a necessary component in this venture. Without a heated tank the oil will not reach a combustible temperature. Feeling confident in the alternative fuel system on the vehicle, I decided to test it and made a round trip of 150km. With that being a success, I pushed the system a little harder and with tools in hand, and extra vegetable fuel on board, drove a distance of 1100km return.
The exhaust, when running on WVO, smells like burnt deep fried oil. The emissions are considerably reduced and there is no sulfur. Restaurants are more than happy to give away the oil, as they have to pay, to have it taken away. It needs to be filter down to about 5 microns before it can be used so there will be no damage the injectors or the injector pump. The possibilities are endless, as any diesel engine can run on used vegetable oil. This is a win/win situation for everyone involved.
