gas question

**bandit95** · 08-06-2008, 01:29 PM

i know trucks arent for gas mileage and i drive one of the better economy trucks in a 06 4 banger canyon, but i want a bigger truck with more power and room. i'm looking at around 04 to 07 gmc or chevy with a 4.8 or 5.3. when you guys arent beating on them too much and just cruising around, what kind of mileage do you average?

mine gets 20+mpg...2wd 5.3 auto, 3.73s, headers, cam, efi live tune...

how do u manage 20+ with a cam and 3.73's? that must be a helluva tune! if u pull it off then i may lean towards camming one myself.

my gas mileage is better with the cam and lt's than it was stock...17mpg from the factory and 20+ after all mods

I had a 02 Chevy 1500 5.3L Ext. cab Z71 4x4 and got 17-18 on the highway.
My 07 Dodge Ram 1500 Quad cab 4x4 20-22 on the highway pending on speed 15-16 in town.

stock 07 chevy 1500 4x4, 16 city and 21-22 highway. Don't waste your money on a 4.8.

The 2WD helps a ton. You lose a few MPG with a 4WD vs. a 2WD.

The heavy chevy gets 14 miles to the gallon coasting in neutral downhill with a good tail wind. I avg. 9-11 in the winter time in 4WD with the plow on. 6.0ltr. with aftermarket exhaust. No tunes, no internals, just loud.
