    Default 2008 Sierra 1/2 ton Crew Cab w/6.0

    Any input on the reliability and gas mileage on a 2008 GMC Siierra 1/2 ton Crew Cab w/6.0 litre? Truck has 79,000 on it. Had heard they have lifter noises at 100,000 mi.?

    My 04 2500HD with the 6.0 get's about 11.5mpg with mud tires and 12.5 with AT tires. I've only got 76k on it so I cannot comment on lifter noise at 100k.

    Any truck with a 6.0L is not a 1/2 ton its a 3/4ton. The 4.8, 5.3, 6.0L are the same family and share the same design and are very reliable and should get to 400000 miles with out any problems.
