Oil Pressure Gauge - What's it good for?!

[gav]

Sorry - complete newbie question...

My 1992 Nissan Safari has an oil pressure gauge (kg/cm2) - what's this useful for and what should I be looking for that might indicate there's a potential problem somewhere?

Cheers,
Gav

Your oil pressure in your engine. Peace of mind knowing you have oil running through your motor. It should sit about halfway when running, a little lower at idle, if it increases above that something is wrong. It is also of assistance in knowing oil is being picked up and sent through the motor when truck is on steep angles for long periods ie Winching up or down steep long slopes, truck on angle sidways for long time.

Cheers albundy - much appreciated.

Mine never seems to get above 1/3 of the way up the gauge.

some time get another one custom one fit that for more info and peace of mind

Also, as an engine wears and gets older the oil pressure slowly drops. So a pressure gauge over a long time can tell you the condition of the main, big end and cam bearings.

Could be getting a little tired, I'm thinking it has a few K's on it.

My engine compressionn was within 3% of manfactures specs, hence I think halfway is were it should sit.
