Hey guys,

I am aware this is gonna sound like a stupid question but i have recently got a 98 Pajero and have extremely limited motor related knowledge (i am slowly learning)! My instrument cluster has an oil pressure gauge and i have no idea what's normal pressure! i know i don't want low pressure but how low is too low? what is normal idle pressure? and also is it meant to move much or not really? Also i wondered if anyone knows any good beginner tracks around the Newcastle area?

I suggest you spend a few dollars at Autobarn and buy a workshop manual which will answer this and presumably the many questions to follow.

Engines have really low pressure at idle,usually under 10 psi.
Most engines with a good oil pump and bearings get over 50 psi at 2000 rpm.
The danger sign is when the oil pressure goes quite high when cold and drops away to nothing after about 10 mins when warmed up.

An oil change or thicker oil can bring the pressure up 5-10 psi.

Factory dash gauges are only a general indication.
How much they should move depends on how they are calibrated to engine pressure,usually about 1/4 to 3/4.

If you really want to know the operating pressure you can screw a mechanical gauge temporarily into where the oil pressure sensor goes.
Gauges can be hired from some parts stores but they have probably become cheaper to buy.
You would need the engiine test procedure from a manual.
Most mechanics could do it for you

Hi Howard, I'm from the Newcastle area too, and newish to 4wd. I printed out the guide map for the Wattagan mountains from here, and had a great day finding out what my Jackaroo could do, without it being too difficult for me, or too scary for my wife. There are a lot of tracks in the Barrington area, around the Upper Allyn river too, I have camped there a bit, probably need a day to check out either of those two. Happy driving, Dave

Not sure if yours is a diesel or petrol.
When engine is warm.
My diesel on 15/50 oil is 2 at idle, about 4 to 5 when running.
Max oil pressure is about 6.
Heavier oil lifts that about 1, lighter oil drops it about 1.

Hi Howard
Mines a diesel also.
Runs around 1/2 at idle, 2 when driving.
Wouldn't know what is correct as I don't pay too much attention to it.
Was a post about this on the Vic Pajero club a while back which showed varied responses.

As said above Wattagans are a must. Something for everyone.
Get out to Stockton also. Best to have another vehicle with you for both.
