Oil Gauge Question

[NRV155]

Just wondering if this is a normal reading for cold weather? This was normal driving home from work about 10mins ago, no hard boosting or anything, just cruising. And what exactly does this gauge tell me?

Thanks for any help.

Either you got no oil in ur sump. Or it is an oil pressure sensor problem, or oil pressure guage problem. I could keep going, but start with that first. Gauge should be reading about 4. If that guage is reading correctly and the car was not idling when you took that photo, I hope you work really close to home because you could cause some serious internal damage if you drove like that for a while.

In normal to warm weather, it reads between 4 and the bar below it. Its never read above 4.

Close - If that was indeed a true reading, I would think the motor would be dead after the first good hit.

There are two senders;

- A "on / off' type that illuminates when there little to no pressure

- A varible pressure sender that drives the gauge

If a little red light appears under the needle then you are in trouble.

I would say your like 99% of all the other Skyline owners with low readings... you have a dud sender / gauge.

Replace sender with a new one, or go after market asap. You know what they happens when pilots don't trust their gauges

The other option is of course, the backing plate has come off your oil pump, preventing you from reaching proper oil pressure. Could get it checked out at a shop with a proper gauge.

I did oil change and everything but the gauge still goes haywire. Its all over the place when i drive, like near 0 or it will just jump to 2 then 4 then 0 again. The red light has never come on though. I was also told just to worry about the red light aswell and get an aftermarket one, so thats what ill do. I initially thought the red light was linked to the needle but ive had the needle sit where it does when the cars turned off and no light came on, and the car was still running normal. I was also told i would hear it if there was a problem with no oil pressure anyway.

Its just the std gauge/sender dying i'd say

My one does it to but i've got an aftermarket gauge aswell so i know theres no problems

But if you're worried then yeh take it to a workshop and get them to check it with a mechanical gauge.

Make sure they do it when the oil is at FULL operating temperature though, not just warm.

That happens when you're not flooring the accelarator as i have the same problem as well. Example; when driving at a normal speed like 80km 5th gear for a while, the needle just drops close to bottom. But when i shift a gear down and accelarate, it goes up again. On cold it's above 4kg/cm2 for a while, then exactly at 4kg/cm2 then warmed at 2kg/cm2. At cruising and then suddenly brake till car stops, the oil pressure drops to the same level as well.

I wouldn't worry too much as it happens so frequently on my car. No oil leaks anywhere and i change the oil at every 5000km interval.
