Checking Your Miles To Gallon

[Diesel Freak]

I hear so many different issues with poor mpg. Who uses the calculation method and who relies on their on board computer saying what they get?
What kind of mileage are you also getting in those rigs?

I use the calculation method. It really is the most accurate. The Lie O Meter goes from anywhere from right on to off by 3mpg per tank. On average I get between 15 to 17 mpg.

I use the truck computer to calculate mileage, if nothing more than as a baseline, because if it is incorrect, it is steadily incorrect.

That is my

I have used both, and the dash is pretty well on. Ours was down to 6.4 today.

I always use the calculation method and use it to check the accuracy of my Lie-O-Meter (which is, surprisingly, usually correct or a tenth too low). My '03 has 147K and gets around 13mpg in the city and 17-18mpg on the highway if I'm not too heavy with my foot. My last 2 tanks have been 16.4 mpg's. Not bad for 3 1/2 tons and a big block! Oh yeah, and I put in 8oz of Power Service Diesel Kleen (silver bottle) every fill-up.

I drove to the PBR event this past weekend in Greensboro, NC, driving up I was running between 70 and 80 and got 14, I tried to behave and drove around 70 on the way back and got 13.8 I just turned 5500 miles so I know it is still breaking in.

That's one way to look at it. But, a couple years back I heard many PS owners complaining about only getting 15mpg. They wanted 19 and 20. I would love to see 14 or 15 now with this 6.4.
