Hey guys i'm thinking of getting a truck as my next vehicle and just wondering what kinda gas mileage the various models get mainly like the 5.3's in different cab levels and the SS's. I'm wondering real world gas mileage like you guys see not what has been reported. thanks alot!

 

Reg cab short bed 4.8 with minor mods and a heavy foot .... avg'd about 14 ... now with efans and magnaflow exhaust im at about 16mpg city. On the freeway im in the 18-20 range (3.42 gears )

 

Driving somewhat normal I cant get around 410miles outta one tank. But Im too lazy to to calculate MPG.

 

410/26gal = 15.8

 

on a very good tank with alot of highway driving i have gotten 440 miles, but normally i get around 390-410 miles per tank so i guess somewhere between 15-17 mpg, the 4:10's are killing me but its worth it

 

22 on the freeway, 16 in town, climbing a 600 foot tall hill to get home everyday. 3.42 gears, 4.8

 

average per instrument cluster = 11.5mpg

 

I have a RC SB,5.3L,3.42's.Get around 14-18mpg on average.

 

SS...

Daily idiot-like driving: 16.5+

When I drive like the other cars on the road: 19.0

When I put on the blue wig and drive real slow: Not sure, but I'm shooting for 20's!

All of these are per the DIC.
