Another question about gas milage.

RE: Another question about gas milage.
2007 1500 Reg Cab Short Bed 2WD New Body Style 4.8L / 3.73 gears.
I average 18 mpg
Worst tank has been 16, I have got as good as 23.5 MPG Hwy at 65mph.
At 295 horspower don't let anyone tell you that the 4.8L won't do a great job, not so many years ago the 454 was only 230 hp.
The difference between the 4.8L and 5.3L is the length of the stroke wich accounts for just a 20hp and 33lb/ft difference, while this is noticable it is certainly not epic.
Most people who bad mouth the 4.8 have not owned it and are thinking of it in the same light as the old 5.0L which was a dog in many applications.

RE: Another question about gas milage.
Another issue about fuel mileage when you increase tire diameter is that thespeedometer thinks you're going slower than you actually are. There's a formula for calculating this somewhere but it's something like if you go from a 31" tire to a 34" thespeedometer is going to read about 50 mph instead of your true speed of 55 mph. This means that your odometer willshow you travelling less on the same tank of gas, hence lesscaculated fuel economy.But of course this lost fuel economy is not true.
