Hi, I think it varies by feedstock, but my understanding is that there is slightly less energy per volume of veg oil/biodiesel. Therefore, when you switch to veg oil/biodiesel from regular diesel the mileage per gallon drops slightly...it doesn't improve. But, the fuel is better environmentally and should be cheaper. Even if the engine uses a bit more per mile, overall it should still be cheaper than regular diesel. Most of these trucks are geared low and that is why the mileage is dismal. I had a friend who consistently got over 20 mpg with the same truck you have. But, he had added a Gearvendors overdrive unit. I have a 1987 F-350 with the International 6.9 NA Diesel engine. When I bought it, it was only getting 12 mpg due to a low differential. I put in a Gearvendors overdrive unit and the RPMs dropped by 500 for a given speed and it got an additional 5 mpg. It now consistently gives 17 mpg. Derek
