#114 of 116 Chevy Truck Gas Mielage by hutch54 Jun 07, 2009 (10:07 am)
Ok....After reading all the post of the gas MPG of the Chevy trucks everyone is complaining about. Well to tell all...I have 3 chevy trucks, One is a 2001 1500 ext cab 4.8L with 290K, Still get 20mpg doing a commute 0f 200 miles over mountian pass everday. My suburban's 1500 4x4 5.3L, well they have gotten up to 23.8mpg. The MPG on my trucks and other chevy trucks I hvave driven can be done easy. Don't start off the line like it the drags, do not use the cruise control, and most for the tucks stay under 65. the Sub's 4x4 speed if under 62 will get the most. Oh, yeah ,,,my brother has a Toyota...gets 15 mpg, and his Ford 1/2 ton 4x4 gets 12mpg. I will stay with Chevy's

Replying to: eaubes (Feb 28, 2007 2:22 pm) I drive a 95 GMC Sierra Z71 with an old school fuel injected 350 with LS1 heads, a k&n intake and poweraid throttle body. Even tho its the original engine(minus the heads) and has more than 188,000 miles, it recently dynoed at 394 ponies. I mostly drive hiway and gravel roads and its been gettin close to 21 mpg and around 19 in town. My question to all you GM guys out there is how come the newer, lighter, mostly aluminum engines with better power ratings get worse mileage? My father owns a 96 Silverado as a daily driver and averages 17 mpg hiway with the 5.7 Vortec. This just shows how a few mods which cost close to nothing (bought heads from friend who totalled 01 Z28 for $50) can repeatedly show results on the hiway and still has the power to tear up my 33 inch BFG"s in the mud!
