I don't require anything of the sort. But you've provided nothing...

Right. The owner's manual, I'm sorry service manual since you think that actually matters, applies to extended operation on a road course, even though the car can't reasonably get to that point with a stock setup.

You don't think Ford has the ability to test engines independently of road- or track-testing cars?

I'm not sure how you think that makes sense, or how you can imply there is no difference in operating at temp X on public road vs. operating at temp X on a road course. Not to mention it's a different car with a different oiling system.

The point of the reference is that Ford considers 279°F oil temperature, *however it got to that point*, to be in the range of "normal". If oil temps are in the "normal" range, surely rpm up to redline/rev-limiter should not be a problem. Different car, different oiling system, yeah, I just threw it out there as a reference. If Ford is OK at 279°F, that suggests that it might also be OK in our cars with similar oil (I think Ford specs 5w20 for street, 5w30 for track usage). At the very least I think we can conclude that the oil isn't failing or breaking down at that point. Also, that 279°F almost certainly has some conservatism built into it as well.

You don't think he was just talking about the negative effect on oil pressure? Or do you really think he meant the oil itself is breaking down?

Here's what he said, it seems pretty clear: "As much as we love doing engine swaps for people, we'd rather not do it because someone spun a bearing from letting their oil degrade."
As we see in the data presented, oil pressure was the same running 5w30 with an oil cooler and without it. No difference, no "negative effect on oil pressure." I don't see how you could conclude that it was oil pressure he was talking about.

Cool, don't use one. It's your car you don't have to. Run a blower with E85 and crank it up to 400 rwhp. Some engines can take it. No one can say for sure at what torque rating the rods let go, so it doesn't matter what you do as long as your engine stays running. Amirite?

FALSE EQUIVALENCE
For the record I have been talking about relatively stock engines and whether or not an oil cooler is *needed* to run these cars on the track. Throwing up something entirely different and presenting it as if what I'm suggesting is the "same thing" is

On that note, I recall seeing someone track their car 14k miles on the same oil and I think no cooler and got an oil analysis that said no excess wear.

Thanks for persevering. I appreciate others' skill at keeping cool defending against an unfair disagreement. I'm not very good at it.

I got mine installed today. I don't have any before but I plan to take my car to a track day in the next 60 days. Currently running 0w20 oil but might switch to 5w30
