How does biodiesel effect mileage and performance?
Mileage and performance are very similar between biodiesel and petro (or DINO-diesel). Again tests vary by engine type, condition, load, test method and fuel used. Some show slight decreases, some show slight increases. A School bus district in Michigan recently reported saving over $4000 last year due to lowered maintenance costs and ½ mile per gallon mileage increase.
