How Many Change Their ENgine Oil After a Lapping event

[Macker]

Curious how many change their oil out after a lapping day, or just wait for the Oil Life indicator to do so.

I did 3 or 4 20 min. sessions on a local track here. For fun, here's a couple of short clips of one run......

I go by track hours. Usually 4-6 hours. You can't go by mileage if you're tracking the car. The interval for the 302S is every 4 track hours.

Mosport...sweet!

I change mine every two events (typically around 5.3 hours each change, sometimes less).

+1. Every 4-6 track hours which is 2 or 3 track days depending on format.

I run towards the long end of the range (maybe even up to 8 hours) in cold/wet conditions, and much lower in hot/humid or high rpm tracks.

Got it & will do. Thx.

Yep, very lucky to have it within 20 mins. drive of my home. Great track. Ever run it?

I change every 6-8 hours. That's usually around 600-700 miles. But in my case I run the car to 7500 pretty regularly and see end of session temperatures of 265-275 degrees. If you are more casual on track you can go 3000 street miles with a day thrown in.

Great info. thanks guys. Think I'll hold off a while yet on changing the oil. I should mention I had a fresh oil/filter change just prior to the lapping day....

If you want to be reasonably sure on when YOU need to change YOUR oil the way YOU drive, have a Used Oil Analysis performed from your next oil change.

Two in a row would be better, but one time will give you a very good idea. Especially if you track the car. I bet you will be surprised at the results.

3-6 hours of track time and will leave it in for the street up to 3,000 miles or 6 mo.

That's usually 3-4 events for me.

I've said more than I care to on the subject, but exactly how do you determine that your oil needs to be changed via a UOA?

I think the main benefit is to know if an engine is on the way out through UOA. Would detect elevated copper levels (assuming bearing failure) vs. the baseline you've (hopefully) already built.

I don't do UOA but I don't have anything against it.

Negative. Maybe some day...

My point exactly. Better for telling you when you're losing and engine not when to change oil. More of a 'no news is good news' kind of thing.

Any recommendations on a good lab to use?

They'll send you a free testing kits and I think it's $25 per test.

I think any will do, but I've only used Blackstone and see no reason to switch. $25 +shipping and +$10 for the TBN, if you believe that's a useful for oil 'life' remaining.

Here's a sample of the Blackstone report:


This was Mobil 1 run for 3 track days, ~4 hrs. and 2,800 street miles.

Thanks for the recommendations on Oil analysis co. guys....and Grant for sharing your analysis.
