Oil Pressure Values please.

[jmec]

Hi. I've just fitted an oil pressure gauge (& voltmeter) using the Wiki guide (very good). Does anyone know what pressure values I should be seeing at, cold idle, warm idle, hot idle, cold 2500 rpm, hot 2500 rpm for an M20 (325) using fully synthetic oil? Thanks. And here's hoping for a couple of bob for xmas to spend on my cab!

No idea at particular revs, but my 5-bar guage usually shows MAX when stone cold, dropping down to 3 bar when the coolant moves off the blue, then down to about 1-1.5bar when properly hot.

Whether your oil is mineral or fully synth won't make a blind bit of difference to your readings It's the weight that matters (5W30, 10W40, 20W50 and so on). My readings are for 5W40.

i get about 60psi or so at stone cold idle, down to about 15 fully warmed up engine and on motorway speed 3000 ish rpm 51 psi

Thanks Gents, yes I should have mentioned the oil spec it's 5W-40 and the readings are near to your info.'
