Went to ormeu on the wkend had some fun in the mud, as soon as I got back on the road my oil light turned on...popped the bonnet open checked the dipstick it was half way. Got home topped I up and the light didn't go away. Been driving it all week oil is full yet the light is still on???? I got a gq single cab 4.2 with an aftermarket turbo. This happened to my Mavarick once but the light went away after some time. Any suggestions?

check your brake fluid and /or get another oil pressure sender

Brake fluid is at half way I'll top it up on the way home and see if it makes a difference cheers.

Mine is the same I just don't worry about it as mine came on after playing in the mud aswell!

Brake fluid????

Had this on mine once, after playing. I have a guage too, so I knew it was all good.
I had to put a new sender on mine.
Hopefully that will sort it for you.

BTW, the light is not a sensor for level, it means "stop, your pressure is low". If you have any doubts then that's the time to get it towed.

It would have to be the oil pressure sensor wouldn't it? If it had no oil pressure it wouldn't be running still, it's not a oil level light it's a oil pressure light
The low brake fluid level makes the hand brake light stay on btw

The oil pressure is fine I think. What should it be sitting at? Mines between 4-6 kg/cm2

if its brake fluid the handbrake light would come on. in the sender there is a switch and the pressure sender. sometimes the switch can get stuck or if you have been in the mud the contacts may of got water accross them and the water may still be in the boot over the terminals. take the boot off and let it dry out. may want to for intrests sake take the sender off and manually check the oil pressure. if its ok and the light stays on just get a new sender from nissan it just screws out.

I have had 3 GQ's and the oil pressure switch/Gauge has failed on two of them. It will start to rattle pretty quickly without any oil pressure.

yeh its pretty common for the sensor to **** it self you will find quodbazzilion threads on it. think there reasonably cheap from nissan.

140.00 for a new sender from nissan, had this problem almost a year ago. light came on, no oil probs or loss of pressure, was just the sender. thier 140.00 roughly from nissan dealer

My oil pressure sender died causing the same symptoms as you. Mine died after going through a deep river crossing. It was old and it didn't seem to like being dunked in cold water when it was stinking hot!
