    2011 Yukon Denali 6.2

    @Charlie207 it’s insane, can’t touch anything decent near me for less that 500k, I’m glad I bought in 2019 but my house is getting small for my growing family

    2011 Yukon Denali 6L80

    @Marky Dissod i think I’m just going to pull the pan and change the fluid, as it’s new to me I want to make sure I know when the last time everything was done. I already did the oil with royal purple and I figure I might as well do the diffs too

    2011 Yukon Denali oil pressure

    I just bought a 2011 Yukon Denali and was just wondering about oil pressure. Upon startup it is running at about 50 and then after it warms up it is running at about 20 at idle and between 30 and 40 while driving. Are these normal oil pressures?

    2011 Yukon Denali 6.2

    I plan on doing Mobil 1 oil change every 3-3.5k miles, I would think that would be pretty good right? Any other maintenance that can help me? And also how much money do you estimate it being to do the true AFM delete? I’m hoping to get 250k out of this truck or even more and I’d rather do my...

    2011 Yukon Denali 6.2

    I just purchased a 2011 GMC Denali with the 6.2 and I’m wondering about the known lifter issue? How common is it in this year? Seems to run fine I just have concerns from all the horror stories.
