I bought this truck with 98,000 miles on it and have put about 22,000 more miles on it since acquisition. It does not burn a drop of oil and it rides better and runs better than my previous 2006 Chevy Avalanche.I hope to keep it ten or 20 more years. It has the AFM listed on the window sticker as all 5.3 s did in 2012. I can not tell when it changes,I can only tell when the tranny changes when driving away. All the power I need and more. It gets about 16 or 17 MPG on average. I have been very happy with this truck and got a good price on it. I did a lot of searching and praying before I bought this truck. I have read the horror story's that some have had and I could never buy or want a new one. I think the secret is the technicians ability to tune the engine and tranny to the proper specs. Good luck to all GM truck owners.

Best Overall Truck I've Owned

2012 GMC Sierra SLT Crew Cab 4x4 6.2L: Easily one of the best all-around trucks I have ever owned. This truck does everything well with ease. Whether I ask it to push through 2 feet of Michigan snow getting to work or pulling my 8,000 fun mover it never has any issues. Anyone looking for a reliable, hard-working, and downright fast truck, the 6.2L with the 3.73 rear axle (available on the max trailering package) offered in both the Sierra and Silverado is a must. 403hp 417ft/lbs going through the buttery smooth 6-speed from GM rivals most engines put in trucks today. the only downside I have found since owning (101k miles on the clock, 35k in my ownership) is h fuel economy. These particular trucks are rated at 12/18 and get just about that running premium, which can definitely break the bank. Running E85 will save upwards of $.75 a gallon but will drop your highway economy into the low teens. Overall, fantastic truck coming from someone who has owned a 2015 Silverado 5.3L and Avalance 2500 8.1L.
