Gas mileage less than when new
By Calvin Bowlin on


2008 Chevrolet Silverado 1500 LT1 4dr Extended Cab 4WD 6.5 ft. SB (4.8L 8cyl 4A)


Had a water leak in the cab due to improper vent installation from factory, lots of wiring issues from water damage, fuel mgt. system robs power and does improve mpg, truck averaged 18-21 mpg for the first 6-8 months. now averages 15.3 hwy with cruse set at 65mph, 13-14 overall. Previously had a 2004 with 5.3 engine that got 19mpg on hwy at 80,000 miles, 2004 was much stronger hauling hay and a boat, 2008 5.3 runs at 211-212 degrees. Seems too hot for just going down the road empty. I am not convinced GM has improved the truck over previous body style. rear bumper is nothing more than stamped sheet metal, very cheap,

Best Features

color, quiet, leather seats comfortable

Worst Features

use better quality tires, needs rear bumper that can be used, not just look good, fuel management system does not work and robs power, fix that,
