oil pressure
i have recently fitted an oil pressure gauge to my 95 classic. have no mods other than sti panel filter, standard 260ps.
on warm idle it sits at about 22psi/1.5bar, does this sound about right.
going out for a run now as i cant remember what psi is at when tootling along at 60, i think its about 80-90.
cheers chaps
engine is on 131k but was in bits to have a new crank, std oil pump, timing belt, piston rings and so many gaskets/seals its not funny at 95k
oil is millers 10w40 fully

It will depend on many things, not least of which are age of engine, age of the oil and the grade of oil in use.
to give you an example, mine was running Motul fully synth. I's done around 4000 miles since a fully forgted rebuild. Oil pressure was 6.6 bar cold, 5.6 bar hot, 2 bar hot tickover.
Yesterday it had an oil change and was filled with some stuff called Royal Purple. It now runs 8 bar cold, 7 bar hot and 2.6 bar hot tickover.
FYI, 1 bar is roughly 14psi.

cheers chaps,
have been out to check,
cold start 80-82psi(5.51bar)
warm idle 22psi(1.51 bar)
60 mph in 5th, just shy of 3k, just over 73psi(5.03 bar)
i dont think im far off, just dont recall seeing anyone else in the 1 bar region. engine ticks like a swiss watch, so cant complain.

Cold - 6bar idel, 6.5bar running (never reved high at this temp anyway.)
Warm - 2bar idel, 5.5bar(ish) running, peaks at 7.2bar when pushed.
Oil is Millers CFS 10w60.
Idel revs would have quite an effect too, mine idels at 500rpm(ish) if it was 750rpm it would be 3bar warm idel.

are all these gauges calibrated within half a bar? the difference of .5 bar really doesnt matter, the problem lies when the pressure is outside its normal zone. Use the gauge as a good reference, not as the be all and end all of exact oil pressure.

My 95 wrx is 15psi warm idle and has been for the last two years since i fitted it,
I use millers cfs 10/50.
Its an auto engine and does not have the modine oil cooler but not sure if that would make a difference to the pressure.
