AVG MPG for 10/25/05-12/16/05 which included half a dozen fillups w/o additives: 22.6 MPG

AVG MPG for 9/2/05-12/16/05 which included 12 fillups w/o additives: 21.7 MPG

During the next 12 tankfuls, I will add 4 oz. of PowerService DieselKleen to the tank. I will calculate the average MPGs with the additives, then for the 12tankfuls after that, I'll calculate the average MPGs without fuel additives to see if there really is any benefit mileage per gallon wise to using additives. Keep your eyes peeled.
