I'll likely rotate in R&P into my oil changes by using it on every third change at 5k intervals on my 2025 Pathfinder.

Just bought at $49.57 plus tax.

I just had three jugs delivered and pulled one off the shelf at Walmart. Have not had a problem getting QS Euro 5W-40 in the last 5 years or so using it.

The PCV valves are known for not lasting very long in the EA888, I used to replace mine at around 40k intervals as maintenance. Not extremely expensive and easy to replace. I'd start there.

Provided it does not touch anything when the engine rocks under load.

If you log a bunch of bone stock vehicles you will see 2-3 degrees of knock retard quite a bit, especially FI cars. Thankfully, a KR gauge is not a factory option otherwise we would have a forum called bobistheknockguy.com.

Nope.

Unfortunately the BRZ does not offer temp reading in digits but a graph which gives you a rough idea. In roughly 80 degrees at Thunder Hill I would run 20 minute sessions without any concern of oil temps without a cooler. I run advanced group for reference.

My '23 BRZ currently runs K&N 5W-30 on track with no cooler. Will switch to Quaker State Ultimate Protection 5W-30 next change.

How about lifters? Same opinion as for the bearings? What is your go to oil weight for a SBC which would see some additional heat and load over a daily driven vehicle?

Any reason why a 5W-40 Euro oil would not do well in an autox vehicle?

Done. Quaker State Ultimate Protection Full Synthetic 5W-30 Motor Oil

Mainly QSFS, it is a great value.

What are your tire pressures coming in from 15-20 min?

If you are at 1k miles now I would watch the oil level and not baby it. If you have manual mode occasionally decelerate using engine braking. My hunch is consumption will decrease.
