2008 Chevrolet Silverado 1500 LT2 4dr Extended Cab 8 ft. LB (5.3L 8cyl 4A)
New system that cuts 4 cylinders off not so effective. Best mpg's 18. Expected better. I'm not an aggressive driver and usually maintain a constant speed. Mostly highway driving. Very nice ride, but not as responsive as my Nissan Titan was at 16.5 mpg
Needs to be more responsive with get up and go for merging into traffic.
