Do you trust the "grease monkeys" to service your H2's?
 

As in oil changes. NO, I'm not going to change it myself (before I get 20 replies saying to do it myself)

I have taken my silverado the the local fast lane oil change place for the last 5 years, and never had a problem. Would you guys trust taking an H2 to them, or do you only go to a dealer?

Is there something different with a Hummer, or is a GM 6.0 Liter a 6.0 Liter engine regardless of the chasis?

I will do it myself but you can go to a good independent shop. I would not take it to a fast lube place

Agree, I will never take any car to a fast lube. find a good local, family owned shop with a good reputation. try using yelp of something like that to look at reviews.
