Would you switch to Mobil 1 synthetic at 42,000 miles?
I've been using the dealer for my oil changes thus far and want to go back to doing my own. Would you switch over to Mobile 1 at 42,000 miles or keep using the GM oil?

I would not worry about switching to a synthetic engine oil at this time. you may have had synthetic put in it at the dealership if you have a 2007 engine and newer.
The mobil 1 I use is now Dexos approved . I have found this to be very good with reduction of some of the engine noise on cold starts in very cold weather for the first 2 min.
I hope your not using regular dino oil as this oil is not good for these type truck engines even if it is an older one. make sure you use the proper viscosity. this should be 5-30wt. also get / use quality oil filters no fram filters. ac delco/mobil/napa gold/wix/purolator pure one .............

What do you guys recommend on a 99 Yukon with 156K? I switched to synthetic a year ago and noticed a need to add a quart after about 1500 miles. That doesn't seem right.

I used Mobil 1 ever since I bought my 1998 Suburban-in 2007- with 195,000 miles on it
223,000 now-runs fine
I did switch to 10w30 extended service-since I'm lazy
and my idle oil pressure was 20 psi-which is plenty- but went to 10w30 instead of 5w30
live in hot climate-NOLA-and plenty of miles-hence the 10w30
sticking with 5w30 probably would have been just fine-
if I live farther N I certainly wouldn't use 10w30- 5w30
we are hot most of the time-and rarely get to 30 degrees-1 two days a year maybe1998 suburban-
