when the light came on--- so that was 7000-10,000 mile oil change intervals?JPayne said:Always get the oil changed when the light comes on within 1 full tank of gas. I thought the 2010 was already programmed to have you change the oil at less miles since they had so many problems with the 2009. Don't know the brand of oil since my wife has it done normally and we tell them to put in whatever the manufacturer recommends. I check the oil about every 2 tanks of gas and it has never been less than halfway between the top and bottom marks but I went ahead and put a half quart in just to be safe and that only happened 1 time. Thanks
back in 2009/2010---- I, and several other members who had used oil analysis noticed that the oil life was not reflecting what the oil life monitor was showing.
the oil was much more deteriorated than the monitor showed. The Direct Injection engines were beating up the oil big time. Others noticed that they also had highly elevated levels or iron- which I believe was iron being shed from the timing chains.
I ran several Used oil analysis to get a good basis of oil life.
I use regular Valvoline. I settled on 5,000 miles or 50% Oil life.
Eventually- GM updated the OLM on the 2009's.... the oil change interval was now- 5000 miles.
I also check my oil level- and make sure the level remains up above the full mark.
