On tv last night I saw a gmc commercial that said they have 350 horsepower and get upto 27 mpg. Ford better do some work if they want to keep up with that!
Last Summer I got 23 with the 5.4 I used to have with the cruise set at 100 and good conditions. My Dad has a friend that just bought a new '07 chev and he complains that his mileage is very bad.
Lol i doubt they get that the have that deactivated cyl so cruising only 4 cyl are running then when you step on it all 8 kick in gmcs trucks dont have 350 hp either maybe the 6.0l but the 5.3 has like 315 320
