"This truck has been great. Gets great fuel economy and handles great. When driving highway, if you drive 80 or so, fuel economy is about 23-25 as it stay sin 4-cyl mode a lot longer. Driving 70 on the highway, fuel economy dropped to about 18-20. It is a snappy vehicle, but with new pipes, the transition to 4-cyl mode is very odd and sounds like the transmition is slipping. It doesn't quiet have the power as the older chevy's but still is a good overall truck."
"My Silverado has upgraded to the 6.0 VortecMax with a Z71 package and it is powerful, economical, and a real pleasure to drive everyday. On average I get 18 mpg in town and got 21 on the highway. I put it on the dyno and pulled 320 hp and 380 lbs of tq at the wheels. That is about 400 hp and 450 lbs of tq at the motor. I plan to keep this truck at least 30 years like my 1978 chevy truck. Maintain your truck and it will reward you."
