I have a pro sport oil pressure gauge. When running the car driving oil pressure is stead and up around 6/7 bar. When I'm idle or change gear clutch in it drops to about 4 is this meant to happen?

Yes, the pump has a pressure release valve, and is driven by the cambelt..

4 bar at idle is very good, when hot I get an average of 3bar at idle. or less if the car has been driven hard/tracked etc.

Perfect thanks for the reply. and when driving etc mines around 6/7? i was panicking that something was wrong

most sit at a little over 6bar when hot, so yes that's fine, 7 would be a peak when cold at a guess.

Sounds perfectly normal and healthy

just me

4 bar on warm idle?

I only get about 1.8 bar at idle, using millers 10w60 nano, is there something wrong with my car?

I get just over 6 Bar when starting from cold and no lower than 1.4 at hot idle. I use Fuchs 10/50 Pro S. Steve.

Around 30psi sounds ok for a 740-750rpm idle. On 10/50 mine is at 35-40psi (2.35-2.68bar) but at a mapped in 900rpm idle.

The 4bar(59.5psi) is a bit unbelievable if the idle is the normal 750rpm with the engine fully warmed, but then I saw that it was on a Prosport gauge. From experience (of others Prosports) I would doubt the accuracy of that reading.
From the OP's post I would assume this is his first experience of an oil pressure gauge?

yes this is my first experience just took it for a run warmed it up. oil pressure is now idle about 1.5psi

Your engine is fcuked if the oil pressure is that low!

kris1990

what should it be at roughly?

i think you meant 1.5 bar not 1.5 psi hence his joke

kris1990

ah get you now!! aha.

New to all this!! had me absolutely bricking it there
