Im new to the Chevy brand. I just bought a used Yukon Denali with the 6 liter engine. I know it's all relative, but in general how many miles can I expect out of this engine? 200k? Who has the most? I want to drive this thing for a LONG time. I sold a Ford F250 Crew with the 7.3 diesel. I was never worried about high miles with that. Thanks for any replies. By the way, this Denali is so nice I actually feel guilty driving it.
