"Veg My Ride teaches you how to convert your diesel car to run on used veg-oil. No need for expensive biodiesel, fill up at most any restaurant for about .15/gallon! Waste fryer oils, collected from your local restaurant are the least expensive alternative fuel solution, and by far the most readily available. "Veg My Ride" shows you how to install a dual tank conversion. This means you still have your factory fuel system and tank, and the ability to run on standard petro-diesel at any time. This system is IN ADDITION to your factory fuel system, providing the most reliable fuel system."
