Got second oil change a few weeks ago at ~12,000 miles, triggered by car alert. Interval was way shorter than my 2012 GT.
So I ordered an oil analysis.
Results interesting. Main interest, the viscosity/additives were still good. As I expected.
However, the lab said there were still break-in metals in the oil, so extending use not a good idea. They also pointed out it could create warranty problems, not changing oil when indicated.
So, assuming my change rate continues at about 6,000 miles, I expect I'll hit 24,000 as warranty expires. I'll get another analysis then. I expect then that I will start extending miles between changes.
