So I have a 2011 Terrain and I have a question. How often do I get the oil changed?!?!! I do mostly highway driving - 150 per day (125 hwy) - I'm not sure if that effects it or not. My problem is I thought it was every 3500 miles... but then I heard more like 5500-7000 since I probably have synthetic. OnStar sends me the diagnostic report monthly and says I don't need to have any maintainence until I hit 14000 miles!! I know that can't be right, but I am assuming it is adjusting because of the oil life/miles driven already.
OnStar states no maintenance required - in their maintainence schedule it says this:
"Maintenance I Service Package
• Perform when Change Engine Oil light comes on or within
10 months since vehicle was purchased"
If I still have 55% oil life what do I do?
Any and all help would be great.
