I couldn't let my car go 7-8k or even 10k without an oil change, even running over engineered stuff like amsoil (syn).
Whew.
Carry on.

It's not the car you drive, it's how you drive it.

I'm with you - cheap insurance for prolonged engine life. Originally I was going 4k on BMW Castrol syn, but have since gone back to 3K...and I have yet to have any VANOS or CCV troubles. Not worth the little bit of extra savings to me.

I think without drawing a Blackstone sample and doing conservatively what they say, you're just throwing your money away. Even at 7500 miles, very likely, your oil is performing like new regarding additives.

Brett doesn't drive his ZHP often enough to warrant waiting till 7500 miles. I don't think he drives it that much per year, even. For him, it would make sense to do it sooner.

Yes it's those half track days that will get you!
Actually thinking about why I got high lead and iron (and boron?) readings, besides the crash and running the motor without the filter. After it was fixed, I helped instruct at a car control clinic. During lunchtime I took my car on the skid pad and tried to do some drifting. While I couldn't break the rear tires loose much (255mm Michelin PSS on mostly dry pavement), I turned a bunch of tight circles in both direction. That could have led to oil starvation too.
Also the day before changing the oil and collecting the UOA sample, I changed the filter, loosening the filter housing and letting the old filter drain a lot of old oil back into the filter housing. Maybe that was a dumb move, as oil could have carried trapped contaminants from the filter back into the sump. (Which is the dirty side of the filter, the inside or outside?)
