Oil Pressure

[ducki]

I'm not sure if this has been asked before but I didn't get what i needed to know when i used the search..

my oil pressure goes to about 7kg when cold.. and when its warm it drops to about 4.. i know that is normal as it has always been like that..

now.. after i had an oil change .. motul 8100... while driving the oil would drop to 2.. and when i rev it goes to about 3 or 3.5 but on constant speed is 2 .. (usually 4) and at idle its about 1.5.

but when i turn off the engine and start it again... it goes back to normal.. as in .. idle at 2 , constant speed at 4.. n revving makes it goes to about 5-6..

what is wrong with it?? is it just the oil playing up or theres more to it?

My R34 is exacty the same with the oil pressure!!! The more load you put on the engine of course the more oil pressure you will create.

no you dont.

its revs. more revs more presure.

and if this is off the factory guage it isnt acurate. if not its because the oil is thinner and has less pressure as a result.

i understand ... more load means more pressure ...

but mine sometimes idle at 1kg and at constant speed is around 2kg.. that is abit low... since I've driven this car for almost 3years now and it was never like this before. and when i turn off the engine .. and start again.. it goes back to idling at 3kg instantly.. and while driving at constant speed is about 4kg ..

Hey all, my R33, 96MDL does the same thing, when driving around town its like 3-4 and when idleing its newere between 2-1.5. I used cheaper oils before and have now gone to Mobil1 10-30.. Maybe try changing oil back to 15-50, Maybe its common in sum skylines, either dodge gauge or lazy oil pump, Plz let me know how you go as mine is the same. Cheers

My r33 SI allso same. i just change the oil with motul 8100. b4 i use 0-40 castrol edge. when cold start with 0-40 it goes to 6-7-8.

there is some very good forums on here regarding what oil to use..everyone should read them.

as far as using 0-40 vis for 25det...i wouldn't

0-40 in a RB25 - oh dear.. that is a BIG no-no.

search for more info. poor oil weight choice can lead to premature motor death

My pressure gauge reads zero or half-way.

I think the sensor is bad.

that means the oil not suit for the car change back to 300V or HKS one
