Robert Tomey, a McDonald's franchisee owner, has put his leftover french fry grease to a good use: fueling his car. His stores, he says, produce about 10,000 gallons of
excess oil each year and, after having a simple conversion performed on his car, he now has more than enough to get
wherever he's going. In fact, Tomey says that 20-30 cars could be powered by that amount of oil. The grease is
processed in a way similar to regular diesel fuel.
And Tomey is not the only one who does this. His conversion kit was purchased at Grease Car. Their conversion kits can cost up to approximately $2,000 and their emissions statistics are intended to provide potential consumers with an idea of how they'll be helping the environment if they convert a diesel car to run on vegetable oil. There seem to be many people who have successfully converted their cars, so it is possible we may see even more of them in the future, especially if McDonald's began to recommend this as an option to their franchisees, since it does seem like a great use for leftover grease.
