Oil pressure - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I tapped in off the Oil pressure sensor from the oil cooler plate(mishimoto cooler), at cold start pressure was @100 psi(only have a 100psi gauge for now). Once warmed up, at idle held about 20psi. Driving in 6th gear, 2-3k rpm around 50psi.

I’ve read people getting 10 psi at idle.

I have a Killer bee Oil pick up tube since I’m boosted.

The car itself, 2020 Brz anyone else have these pressures?

Those are normal numbers.

What is the "oil cooler plate"? Do you mean the sandwich plate? What gauge/sensor is this? What oil weight?
Your numbers seem good, but they will differ a bit based on where you're sampling from.
At least you know if it's ever not reading at what you're used to see, the road may get bumpy

Yeah i meant the sandwich plate, its just a cheapo glowshift until my aem ones come in.

Im running 0w-20, JDL turbo, upgraded radiator, fan shroud, oil cooler and waiting on a vented hood as well. Trying to keep temps down as much as i can in arizona.

I think once my AEM gauges come in, ill be going off the OEM oil sensor location

I spent 2 weeks in Tucson years ago, sometime late March.

Highs were in the 30s here in Vermont. During my stay, it was 80-90 in Tucson- I can't fathom trying to manage oil temps during summer, best of luck!

Being you are FI and in a warm climate, I would keep an eye on it. Min pressure at idle per FSM is 7.3psi at 176F oil temp. If you are getting the car hotter in traffic you may want to go to 5-30w. Recommended oil pressure at 6k RPM is 73psi at 176F oil temp.

Yeah ive done all i could for now, next step is vented hood, and maybe figure out a way to cool the oil a bit more. Driving to and from work 30 miles one way all highway, oil temps get to about 205F

Something seems weird about this. The mishimoto is sized about right. Where is it mounted? Are you sure you're getting good airflow?

If he's doing the highway in Arizona, ambient is probably 106f this time of year. Who knows how much heat the pavement radiates, and he's probably averaging 80mph, which is pretty high in the revs for a long time.

205 doesn't seem unbelievable, but I didn't get to run mine for too long in temps over 70f

Yeah. It's not awful. Good point about ambient temp.

Capt Spaulding · 05-16-2021, 08:21 PM

Actually, in those conditions at that speed 205f seems downright reasonable. In deep south Texas at ambients of 100f +/- the oil temp on my NA ran just over 200 at 75-80. Over the pandemic I installed a o2w wrx/forester cooler and haven't had a chance to do an extended highway run yet.

Sadly not going 80, I stay around 70 just cause I don’t wanna high rev the whole way & let the temps rise.

I will update more thru the week.

My oil

It’s mount slightly off center

Is it mounted on the undertray?
