Let me guess, it was the computer in your truck told you that you were getting 27 mpg at 75 mph. What did your hand calculations at the end of the tank say? Was it any where near the average of what your computer stated? If you are like everyone else who actually hand calculated their fuel mileage, you would have found out that those mileage computers were not very accurate back then as much as 7 mpg off. Although they have improved over the years, they still or off depending on the vehicle. So yeah, your computer may have told you that your were getting 27 mpg, but if your mileage computer was like everyone else then you were probably getting much less.
I should have used the American gallon.. which is about 17% smaller so my mileage "hand calculated" was 22.47 miles per US gal... not bad for a 2005 3500 CC CTD with 6" lift Road armor bumpers front and back and 10 X 20" wheels with 35" tires...

So, how does burning less fuel create more smog?:R
