JUSTIN CARVEN AND GREASECAR IN KIPLINGER'S PERSONAL FINANCE MAGAZINE, DECEMBER 2006
Saving the World With French Fries--Justin Carven's business sells kits that let diesel cars run on vegetable oil.
A typical fuel tank holds 15 gallons. Where do people get that much vegetable oil? Most of our customers are using recycled cooking oil from restaurants.
So I can get all the fuel I need at the local fast-food joint? Restaurants can produce as much as 100 gallons of waste oil per week, which they're willing to give away. Plus, the converted vehicles have one tank for diesel and one for vegetable oil -- so you have backup fuel.
