  1. I have a GMC Sierra Denali 6.2L that I only drive on weekends. ( drive a work truck M-F). I use Mobil 1 oil and my last oil change was back in April of this year. The oil life indicator says I have 63% life on the oil. Should I change the oil since it was last changed back in April? It’s the whole mileage OR so many months thing that has me wondering? Thanks for the advice
  2. Well I read somewhere on the forum that we should post when we get a new Gm truck. Traded in my 2002 GMC Sierra Z71 for this sweet new ( new to me) 2012 GMC Sierra Denali. I've had it for about a month now and absolutely love that 6.2 L. 45,000 miles, MBRP dual exhaust,Volant cold air intake and a Extang signature series Trifecta tonneau cover. Now all I need is a Black Bear tune and I think it's complete! Any other mods I should do?
  3. Sorry forgot to add, the truck has 45,000 miles on it
  4. I have always owned a GM vehicle, shoot I bleed GM blue. I just purchased a used 2012 GMC Denali AWD. How reliable is this AWD system? Anything I should be aware of? special maintenance needs,things to look out for? Never owned anything AWD so I am just a bit reserved about the unknown. Thanks in advance for your valuable advice!!
  5. So I am guessing my 2012 GMC Denali did not come stock with a remote tailgate lock? It seems difficult to wrap my head around why the 2008 Chevy Avalanche I once owned had a remote tailgate lock from the factory and my top of the line GMC Sierra Denali of the time (2012) does not...weird!!! I guess GM overlooked that option for the Sierra Denali..I always thought GM was looking forward and not backwards.
  6. Just bought a used 2012 GMC Sierra Denali. Did this truck come with a factory tailgate lock operated by the remote or is it a manual key lock?
