Originally posted by DelmerI met a guy that drove across the country using McDonald's used oil. He did have to take time to filter it, but his car smelled like McDonalds fries when he drove.
Several people I know are running old VW and Chevette diesel cars on waste vegetable oil that they get from fast food places. As far as I know there is no loss in performance. However it apparently does take considerable time and work to filter the oil until it is clean enough to use for fuel.
