Hi guys I am new on this site so bear with me. I have an R32 GTR which I had the oil changed about 2 weeks ago. I was using Mobil 1 Synthetic, but heard and experienced bad things with this oil (using oil in a new motor) so I have changed to Motul. Since I have had the oil changed I have been experiencing low oil pressure at normal running temps! The motor is reasonably new probably 25000k, the only thing that I can think is that I ran it with low oil for 1 day. The motor is not using any oil, but what worries me is that it sounds more rattly than before! Am I worrying over nothing? Sorry for the long post.

hey,

i have the same problem just happend to me yesterday my oil pressure sometimes was really low and sometimes normal but my temperatures were all normal. I got a bit annoyed hoping it was nothing to do with my oil pump so i checked the oil levels and discovered it was running dangerously low. I couldnt think of were all that oil went as i checked it all a week before and then i remebered when of my coil packs went on me and the car was on 5cylinders for a couple days while i was trying to find a coil pack from wreckers. I discovered that running on the 5 has burnt a lot of oil out and its really dirty when i checked it last night this morning i am heading to go buy some new oil and a complete oil flush i will tell you if that has cured my oil pressure problems.,

Also sorry for the long reply (noob to forums)

Hi mate,

The factory nissan guages are notoriously slow acting and can often give inaccurate readings (senders play up apparently).

My suggestion would be to get a decent aftermarket electronic oil pressure gauge with warning as they are very fast acting and accurate. I had a Trust oil pressure gauge in my old GTS-t and it would move quickly vs the slow moving stock one.

I am also about to replace my GTR 3 DIN gauges with 3 defi gauges for oil pressure, oil temp and water temp.

It previously sat around 3.5-4 now is about 1.5-2 at idle! Is this too low?

No that's fine. You don't need much o/p at idle and as long as the pressure is good at operating revs (engine under load) then there's nothing to worry about.

What Ronin09 says is correct...the factory o/p gauges and senders are heavily damped and (at best) the readings are a guide only. If your still concerned then have your o/p pressure checked using an accurate (ie calibrated) mechanical or electronic gauge.

I use a HKS mechanical guage that screws into my GREX spin on adaptor, and typically in the morning at first start up it will sit between 3 and 4 bar, and Ive since found after driving a small distance my oil pressure will go down to 1 Bar at idle. I now use this as a guide as to when my engine is upto temperature (not following the std water temp guage) as the oil pressure is lower at idle (oil hotter etc). Im using Mobil S 10w40 on an RB20.

If you replace with the DEFI unit 3 din cluster, for a 32 GTR, are they electronic still? as I know a guy who had one put in and it didn't need the control unit like the bigger gauges

I'm just looking at replacing the std GTR cluster with one of these DEFI ones. they look so cool!!!

sorru for the day late reply. Well I have solved the problem (for my car anyway) I drained all of the oil and then threw in some cheaper oil for a couple minutes to clean out anything else that may be floating around. ONce that was done drained it again and placed good new oil in. I noticed my oil to be very dirty and horribly black. Also when I was replacing oild filter it was literally blocked. Replaced oil and filter and for me I got no more intermitting oil pressures. I am all happy for now anyway

    • Sorry to hear your HFM BM57 was faulty,  did you contact HFM I would hope they would be at least grateful for the information if there was some sort of manufacturing fault, you would hope they would be sympathetic even if your item was 2 years old if it had never been fitted. May I ask where it leaked from ?

    • All of this is making it seem clear that running the Coppermix twin was definitely the way to go, especially in hindsight with how insane tariffs have gotten and the strength of the USD vs yen at the time.
    • That sounds like no chance of even importing one for road registering then Now I see why Duncan wants to check LHD rules for Targa...   I wonder how "bolt in" the AWD would be if you got one imported from the US and swapped it to an AUD one
    • Not to mention they drive like a bucket of bolts! yuck!
