No fuel economy improvement
By Ranjean2003 on


2008 Chevrolet Silverado 1500 LT1 2dr Regular Cab 4WD 8 ft. LB (4.8L 8cyl 4A)


No fuel economy improvement over 04 model even though I now have active fuel management. I have the 5.3L engine with 3.73 gears, flex fuel, and get about 16.5mpg hiway on gas. Wish I could have gotten 3.42 gearing for better mpg, but the catch is to get incentives you must take delivery from dealer inventory and they just don't set them up that way. Both trucks turn 1750 rpm at 60mph. I can set the info center to instant mpg readout to learn when the vehicle is in 8cyl vs 4 cyl mode. At highway speeds, wind resistance forces truck into V8 unless going downhill. And, parked together, the 08 cab is noticeably bigger than the 04 cab = more wind resistance. At 75mph, econ drops to 13.5

Best Features

Cab is more comfortable than 04. Like info center. Center console roomy.

Worst Features

We are not all drag racers, ship more trucks with 3.42 gearing and have better mileage instead of hiring Howie Long to claim you do. Lumbar support for passenger on split bench. Low tire pressure warning too sensitive. Cargo net back of seats. Light under hood.
