Engine oil pressure at idle? - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

SuzaFan · 20th March 2010, 08:15 PM

Guys, what is your engine oil pressure at idle in N?
I have the car model that is out of that "affected engines" range, but, my oil pressure at idle (when oil is hot - 90-100 C) is getting below 2 bar, it gets to ca 1,7 bar (accoridng to Nissan MFD)
When oil is 75-85,90 C, the pressure is 2,1 or 2 bar...
I changed the oil at my first inspection (2000 km), I have ca 5000 km now), the car is 5 months old...
What do you think, should I warn the HPC on the next service about that?

Mine is the same at about 2 bar at similar oil temps, I don't get the oil over 90C, but I would expect your pressures if I did.

Same here, 2 bars, slightly less if the oil is hotter (track etc.) which I guessed is normal as the oil gets slightly thinner.

Hmm, I remember that some guys were talking about 2,2-2,3 bar for high temperature oil at idle... ( I think EvolutionVI said that...)

To your comparision . official Nissan data table

Engine Oil Pressure
Engine oil temperature at 80°C (176°F)

Unit: kPa (kg/cm2, psi) Engine speed
Approximate discharge pressure*
750 rpm
210 (2.14, 30)
1,000 rpm
240 (2.45, 35)
4,000 rpm
540 (5.51, 78)

Hallo mein Freund

Im using 10W60 from Millers,works best for me in my Evo´s,so why not use it in the GTR

SuzaFan · 23rd March 2010, 04:35 PM

Oh, I understand then, your oil is thicker than Mobil1 0-40, that could be the reason for higher pressure...
Thanx!!

thats my new GTR 4000km Mobil 1 0-40 stock oil at 80°
Unit: kPa
Engine speed
750 rpm 190 Kpa
1000 rpm 220 Kpa
4000 rpm 530 Kpa
