Lessons learned from my conversion of a 1984 Mercedes into a grease-mobile
Without any sort of approval from my girlfriend, I bought a 1984 diesel Mercedes-Benz through eBay. Two years later, the vehicle has provided me with nearly 10,000 miles of service on waste vegetable oil (WVO). The fuel may technically be free, but it has not come without a price. Here's how I converted my car, affectionately known as "Chance," to a veggie-oil roadster, and some of the hard-learned lessons I picked up along the way.
