I have during my last 2 oil changes. First one was 3,000 miles, full mobil 1 synthetic. Guys told me to go to 4,500. Second was then at 4,500, and now they've said to go to 6,000 miles. Still had plenty of life on each one, so I'm hoping I can keep moving up towards 10K.
I had extremely high iron on first sample, but it washed out with second sample, other than that, very good, clean engine.
Let's hope for 10K next.
