Low Oil Pressure All Of A Sudden

I was driving around today (in traffic) for about an hour ..went to the shops to buy some new coolant and got on my way ..then I noticed my factory oil pressure gauge (inside the dash cluster under the speedo) dropped to 1.4 or so .. and as I was watching it the needle kept dropping even further and settled at 1.

The engine at this point was fully warmed up and IDLE.

I was worried about what's happening so took it easy and didn't go over 3000 rpm (at which point the oil pressure needle was sitting at 2)

For the next 10 minutes or so whenever I had to stop due to traffic as soon as the car was idle, the pressure would drop down to 1. So I pulled over and opened the bonnet .. check the oil level and it seemed fine. Check to see if I'm leaking oil and nope ..nothing under the car. I did notice the oil on the dip stick looked light brown, I'm not sure if that's normal for this oild (Chrono 300V) So I let it sit for 10 mins or so and got in the car again and drove off.

At first the pressure now was around 1.2-1.4 (at idle) and few minutes later I look down again and now it's sitting at the usual 2 on idle.

What could this be a sign of ?? I've never seen the oil pressure drop below 2 in the 2 years that I've owned it. It's only a daily so only mild mods etc. Last oil change was about 2 months ago and Motul Chrono 300V was put it. Now I'm worried about driving it hard (ie. above 3000 rpm) or listening to the radio for fear of missing some engine noise that could be a precussor to a bigger bang.. and I'm constantly staring at the bloody oil pressure needle like a hawk which is not the safest thing to be doing either.

Any ideas?

Mine did that once.

Don't trust the stock gauge. Nissan oil senders are notoriously bad for it. Also the connectors get crap in em and give ramdomly low readings to.

If you are worried fit an aftermarket oil pressure sender and gauge, or test oil pressure at workshop.

I have and aftermarket oil temp and oil pressure gauge.

Cheers.

lol dennis, i had the same problem man.

i just thought it was just the gay stock sender as the car still drives fine, does it with fresh oil even just 1 day or 20 days old.

im putting in aftermarket oil press gauge in a few wks time so see if it reads differently.

yeah could be just the stock sender ... but who knows, it could be a sign of more serious trouble coming my way. I just recently installed new gauges replacing the stockies but didn't get an oul pressure one as it seemed like too much of a hassle at the time. So yeah, I've got nowhere to put an aftermarket one now unless I get one of those A pillar holders ..but those things are massive cop bait so yeah, not sure what to do :down:

And for all the whingers above I DID search and read for an hour or 2 .. it's usually always the same rah-rah-rah "your factory sendor is probably broken" rah rah rah (see above ;D ) I don't know, it could be ..but I don't like leaving things to chance... but I suppose there's not much else I can do.

Besides it's now back to normal (sits at 2 when warmed up and idle) so not to sure what to make of that drop today ..

      Who has a Infiniti Q60, Q50 (V37)?

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.

      What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
