All you need to know about biodiesel is that you use it like you would diesel fuel. No vehicle modifications are necessary. Just fill up your tank and drive. Biodiesel will burn much cleaner, quieter and with a pleasant odor. You can blend it with diesel fuel in any ratio you desire. Any diesel vehicle can use biodiesel and it will not effect your warranty.
Biodiesel pump price is $1.899/gallon - taxes included
