75 MPH mileage

[sag2]

I posted this a while back.



I was fooling around Friday on my way home from work. Just wanted to see what the mileage change is at different speeds, as the new 04 (HO vs SO 03) is getting worse mileage (15 vs 18). I used the overhead (which was very accurate on the 03) and ran each speed for one mile. The road was straight and flat, and there was no wind, ambient 57 degrees.

80 MPH-14. 8

70 MPH- 18. 4

65 MPH-19. 2

60 MPH-19. 6

55 MPH-20. 4

50 MPH 25. 3

46 MPH (slowest speed to stay locked in high) 27. 2



So the actual numbers are not that important, but what is important is you can't compare your mileage to anyone else. You can see that the guy who drives 50 no mater what, is going to get significantly better mileage than I do. I drive this truck faster and harder than the 03 because it has more power.

You call 14. 8 mpg empty good? I expected 18 mpg from what I read here! :{
