Dear supra community, I require your help regarding logs/data about the oil pressure on the b58 engines (worldwide models).

Occording to the specificatiobs of toyota, my car (and a few others) are below specifications for oil pressure.

we are running around 2.3-2.5 bar on a cold engine.

can other people perform some logging (for exampke via ecutek) which old pressure they are getting?

Conditions:
Cold engine, startup and keep it at idle/stationary. And log what happens.

maybe we can also compare on a hot engine and during for example 3000rpm.

important notice is to also state which oil you are using (or state if it is still the one put in by the dealer).

want to compare european,, american, asian,... cars.

thanks already at those willing to log/show something ;)

On factory 0w-20 oil that has about 2k miles on it, with about 80°F ambient temp, I did a cold start of the vehicle and sitting at idle oil pressure bounces from anywhere between 32psi-39psi. So roughly 2.2-2.7bar or so...

I’m using 5W40 in my Supra.

Oil pressure at idle is between 2.3-2.7 bar at idle.
