~11.5k on one oil change
 

Well, got my 'change oil' light today. Total mileage was 14,550, right around 11.5k total on this oil change. I didn't really want to push it, but I was curious. I just got my Onstar monthly email & it looks like the notice goes on w/5% oil life left.

Cool thing: Onstar sent me a special email notice w/20% left saying 'Watch out' - it even predicted I'd need an oil change @ 14,900 miles - almost dead on!

Cool stuff, technology is neat!

Yeah! I also got the next oil change recommendation for the first time in my OnStar Vehicle Diagnostics Report.

Just had my oil changed at 6000 miles for the 2nd time. Got the report at 7,513 miles saying:

Remaining Oil Life: 89%
Next oil change recommended at 17,700 miles.

I like that, I just might have to start using that system when my maintenance plan is up.
