What oil pressure are you getting? - Page 3

2021 ZL1 with 0W40, PF64 filter. ~38psi cold, ~30 hot, ~60psi at WOT.

What oil and filter you using?

RamAir02 · 07-10-2022, 01:00 PM

Looking at PDR data from track days on Cosworth Toolbox, I'm seeing min 35.4 and max 71.4 PSI. This is with 15W-50 oil.

Based on the pic, it doesn't look like you are fully warmed up yet. Water temp still looks low, so I assume the oil temp was low as well? That cold thick oil will cause a higher PSI reading.

Yes I agree, I never go over ~4000 RPM until my oil hits at least 200 F, and yes at that point the water temp is right where it should be.

Not doing this results in excessive engine wear.

Mine is the same.
Idle 28-32
Cruise 38-45
WOT 60-70

Same here with Mobil 1 0W-40.

I have a 2022 LT4 built on 2/18/2022. When it was brand new, it ran ~40 PSI with 0W40 Mobil 1. I have ~5200 miles on it now after a thorough break in for the first 2000 miles. The oil and rear diff were changed at 600 miles. The oil again at 2600 miles and again at 4600 miles. After warming up to about 210 degrees it runs at 38 PSI. After a couple of hard runs and the oil temp increasing to about 250-260 it will it still sits at about 38 PSI, the running oil pressure does drop from about 45 down to about 40 around 2000 RPM's. If you run it hard, especially in hot weather, change the oil around 2500-3000 miles as the oil does seem to break down and lower the hot oil pressure, both idle and cruising.

Same thing on my 2018/10 zl1 1le
Idle hot 29-30kpa
6000-6500 rpm approx 58-65psi

But look here pls
https://youtu.be/HjktrNheGrw?si=aHGTmcHG05MzIhC1

The oil pressure goes up to over 90psi after pull on the dyno that's very high but has the 2021/2022 zl1 maybe upgraded oil pump?

I have a 2023 LT4 I picked up in April, build date is 2/7/23. At 700 miles and at operating temp my pressure is 38psi at idle with Mobile 0W-40. Just thought I'd throw this out there.

29.6 to 28.7 fully hot using 5-30 AMSoil.

Marozl1LE · 12-15-2023, 08:14 AM

Hmm sounds good what about @wot 5000-6000 rpm

And oil consumption??
