You know how gas is like, all expensive and stuff? If you own a diesel car, it doesn’t have to be. In fact, the good people at GreaseCar can hook you up with everything you need to transform your diesel vehicle from a gas guzzling environmental disaster into an earth friendly awesome-mobile. Plus, depending on the model of your ride, you can get the complete kit for under $1,000.

Basically, if you change your car from gas to grease, it’ll pay for itself in less than a year. Pretty sweet, eh? As an added bonus, the cooking oil doesn’t even need to be fresh. You can work out a deal with a local restaurant and cruise around town for free, all while reducing the size of your carbon footprint.
