Which is the OIL PRESSURE in 1NZFE ENGINE? At idle and 3000 rmp measured with the Oil pressure gauge.

Thanks

At startup, oil pressure is high. I've read 90 psi @ 3000 rpm when cool. Once warmed up, it should be around 40-60 psi and can drop under 20 psi when warm and idle. I did notice switching to 5W20 reduced oil pressure when cold if you're worrying about blowing out the turbo seals.

I've pretty much given up on making sense of the oil pressure. As long as it's not zero, I think it's working.
