Bob and Vianne Shope of Harrisburg, Pennsylvania, had to make a pit stop at the grocery store before heading out to the show. They needed to pick up some fuel for their '88 YJ which they found in the baking aisle with all the other oils. This 85 hp 2.1L Renault turbo diesel from an '87 Cherokee with dual-fuel capability runs primarily on vegetable oil. They use it as a daily driver as well as off-road. Would you like fries with that?
