AMORY, MS – Robert Tomey, owner of four McDonald’s franchises in Texas and Alabama, recently converted his Volkswagen Beetle and the company’s Ford pickup truck to run on used vegetable oil drained from his fryers. Tomey now saves more than $300 a week on fuel. He said that he has enough fry grease to power 20-30 vehicles annually. Tomey bought the converter kit from online vendor Greasecar. According to the report, the vehicles now run more smoothly, as the engine runs cooler. The conversion cost about $1,350 per vehicle.
