Diesel Car Modified To Run ON "Veggie Oil"

   Dave Wetzel, Lebanon, TN, burns used fish oil in his 1885 Volkswagen Golf car, which is powered by a diesel engine. He collects the used vegetable oil from fast food places such as McDonalds, burning 8 to 10 gallons per week.
   His "McDiesel" car gets 40 mpg on veggie oil and he now has 285,000 miles on it.
   Wetzel modified the car to heat the oil to 160 degrees, which allows the unusual fuel to be used during summer and winter. He starts the car in normal fashion using conventional diesel fuel. Once oil is heated up it automatically switches to veggie oil.
   He equipped the car with a coil of copper tubing and runs heated water from the engine through it. Once the fuel has been heated to 160 degrees, a solenoid opens a valve, switching from diesel to 100% oil. The heated fuel is piped forward to the engine itself. Wetzel runs oil through a cotton filter before fueling up.
