I think the issue is that it's a giant question mark. I would imagine everyone knows it could be a bargain, and you have just as good of a car, for 30% less, or it could be a god damn never ending...

Ah, I see.
Is there some rule that something for cars can't be measured in a rational way?
We need to produce figures for viscosity at room temperature and operating temperature.
Definitely do...

Well a few things re: above two posts:

1. Thicker oil is NOT a band aid for oil starvation, which is probably why the cars spin bearings at the track.

2. While the ultimate goal is the correct...

I think that a variable not given adequate consideration is alignment.

You're going to hit mechanical limits of the oil pump at a certain point (rpm), is my guess. It's going to be "volume flow limited." Same volume, lower viscosity, lower pressure, lower mass flow. The...

No crayons needed. You're overthinking it. It's just thinner fluid / less resistance. In general, you'd expect lower pressure with a hotter/thinner fluid.

Yeah a lot of stuff starts happening with reduced thickness and lower density and viscosity of an incompressible fluid through an oil pump based on rpm.

Not to get into semantics again, but flow isn't pressure. Pressure is resistance. Flow is mass/volume per second.

I think it's pretty obvious he means "clearances" and not "tolerances"

I'm not sure how any of this added value to the discussion.

Unfortunately, this is often easier said than done. The BRZ is an exception, and I'm not entirely sure why. It's not like it has some sort of massive air inlet.
