Definitely 0 when not running. Without the oil pump running there is no oil pressure.

Depending on age/condition of your motor and the viscosity of the oil you use, you could see anything up to 7/8 or so when cold, and 4 when warm. The 33 I drive practically every day sits on 4 when cruising on the highway, but my old car used to sit just above 2.

If you're worried, put a second oil pressure guage in to compare readings.

hi all, just wondering if this is normal. I just changed my oil last night but this morning i noticed it was all the way to the top when I first started it, it dropped as the oil heated and sat pretty normal. What is the real concern is that when i give it to it, it rises up past half way getting closer to the top. Im only new to the skyline seen been that i have only had it for 2 months. Is this normal?

Can anyone please confirm if it is normal for the oil pressure to rise as i rev harder...when i accelerate the pressure rises and when i push it harder, ie 4000+, it rises higher getting closer to 8. is this normal?

It should rise as the revs rise......

8 seems high though....

What viscosity oil did you use???

Just changed oil.

i use 5-30 and the gauge reads lower now. Needle sits about 4 when hot and running at revs

the dude at the shop wouldnt let me leave with the oil i wanted...he gave me 20-60...i thought this was wrong but he assured me it was correct. would this be throwing it high? im going to the drags tonight and dont want to blow a head gasket...

i think the oil for stock rb25det is 10-30 or 0-30, not sure if its the same for the non-turbo engines, i just got magnitec 10-30 for mine and its rises with revs and it still runs smoothly (though it doesnt rise up to 8).

Be a bit thick wehn the oil is cold.....

should be fine once warm though......

A 30 grade (hot) oil, ie X-30, is basically designed for the cooler conditions in Japan. Coming summer in Oz, I would think you could probably run a slightly heavier oil, like 10-40. Maybe 20-60 is getting a bit too thick.

gues i wasted $35...damn im going to buy some oil at lunch and go home to do the fastest oil change in history. Oh and when i sell it i can say i change the oil daily....engine care is what im passionate about....i even put in one of those engine tune up things....damn

    • Yes...but look at the numbers. There is a tiny tiny fraction of the number of Joules available, compared to what is used/needed. Just because things are "possible" doesn't make them meaningful.
    • Thanks for taking the time to post that ! If anything changes or happens please do update us. 
    • Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.
    • Ok so I have sorted everything with my uniclutch and  i can offer up a bit of feedback and some things that might help others.    I found problems with factory damper line. Weird shit and had trouble with peddle adjustment    I used this https://au.gktech.com/products/r33-gts-t-skyline-braided-clutch-line?_pos=2&_sid=22b01b9b9&_ss=r Also when adjusting peddle leave a bit of play. You can get into a over stroke condition easy.. Make sure you can push the slave forward after adjusting to confirm fluid can return to master then you will need to pump it up heaps…..not sure why but that’s how it is.    last thing the splined adapter is machined perfectly. If your input shaft is old like mine was I would put a bit of valve grinding paste on it and stroke it like a 15 year old. Just to give it a tad more clearance and to better match it to the spline.    reason is on a near flat shift I have had situation where the peddle returns a millisecond after you lift from the clutch. No slip or anything but I reckon this is due to tolerance on the spline being way tighter than stock clutch and binding for a sec. I think this will go away but also my spline was old. Box is old so I guess I should have checked better. It’s a super neat fit.    it feels light as and holds awesome without any noise
