ClutchBurndout-:( Posted July 12, 2010 Share Posted July 12, 2010 youll flip out when the guage starts to play up, somedays it shows normal, and somedays it shows half what it should be (aka 1 when idle, 2 or 3 when driving) just remember its just the guage. mine does this Link to comment https://www.sau.com.au/forums/topic/328515-oil-pressure/#findComment-5341713 Share on other sites More sharing options...

defari Posted July 13, 2010 Share Posted July 13, 2010 sits on 4 at start up? my stock gauge + greddy gauge goes up to about 6-7 at start up, then sits around 2-4 once warm enough.

StealthX Posted July 13, 2010 Share Posted July 13, 2010 when you guys say 4, 6, 7 etc.. that's bar right? my x-trail is a bit strange, I have almost 140 psi (9.6 bar) then down to 25psi (1.7 bar) when warm Normal but strange.

Moodles2 Posted July 13, 2010 Share Posted July 13, 2010 kg/cm2, 1kg/cm2 is equal to about 14.2psi. Generally the colder the startup engine temperature, the higher the pressure before operating temperature is reached.

defari Posted July 13, 2010 Share Posted July 13, 2010 cant remember what the stock gauge measurement is the greddy gauge is in kPa. kPa kilopascals x 0.145 = poundforce per square inch lbf/in2 i think (someone correct me if im wrong) Link to comment https://www.sau.com.au/forums/topic/328515-oil-pressure/#findComment-5344119 Share on other sites More sharing options...

defari Posted July 13, 2010 Share Posted July 13, 2010 im assuming the op is referring to the stock gauge... I've heard mixed opinions that its not always accurate then again some have said the stock gauge is more accurate than aftermarket gauges.

More accurate than some chinese POS maybe, but I would even trust one of those over the stock gauge.

I just go off my greddy gauge. I have noticed that there is a slight difference between readings on the stock and aftermarket one..but its not a massive difference.

blk94r33 Posted July 13, 2010 Share Posted July 13, 2010 On the topic, are the stock gauges a one-piece assembly? Or does each gauge, ie fuel, temp, taco, speedo, oil pressure, have it's own self contained unit? Would like to change my stock oil, temp and taco for autometer items. Anyone done this? Time to take the cluster out I guess lol... Link to comment https://www.sau.com.au/forums/topic/328515-oil-pressure/#findComment-5344692 Share on other sites More sharing options...

Don't think it could be done without a lot of hacking/cutting/etc.. get a cheap 2nd hand cluster and give it a bash heh Link to comment https://www.sau.com.au/forums/topic/328515-oil-pressure/#findComment-5345645 Share on other sites More sharing options...
Galois Posted July 14, 2010 Share Posted July 14, 2010 yeah the stock gauges are renowned for poor accuracy, after 130k km + whatever was taken off and 10-20 years the sender is going to be a bit rough. mine changes depending on the age of the oil, with idle going from 2-4 as the oil ages Link to comment https://www.sau.com.au/forums/topic/328515-oil-pressure/#findComment-5346393 Share on other sites More sharing options...
