I've just fitted an oil pressure guage and I was wondering what the normal reading should be. The gauge reads in bar, and the car is a 2003 blob sti. What should it read at idle, normal driving and hard acceleration? Any advice appreciated

 

6-7 bar cold idle. 2-3 bar hot idle. 6-7 bar when accelerating above 3-4 k rpm

 

As above

 

yep thats what mine reads.

although oil thickness will have a factor

 

Thanks, didn't expect it do drop that low on hot idle lol

 

That's still 31-44 psi....

 

What is?

 

3-4 BAR is mate

 

I'm confused ???

 

Pressure gauges come in 2 types either BAR or PSi(some have both on) and 3-4 BAR is 31-44 PSI

 

Your gauges are in Bar but they also do them in PSI but this has no relevance to you, lol, My gauges read in PSI not bar and are roughly 90-100 psi on cold start, 40psi on hot idle and 85-90 psi with foot down

Nowhere near 1 bar = 14.5psi

 

Lol I didn't even look at that Gaz,was in auto pilot with reading Jeffs post
It's actually 14.503

 

I know this, but what is he saying is between 3-4 bar?

 

Nothing mate, He gets confused quite easily, I think it was refering to your hot idle which jeff(Alcazar)said was 31-44 psi, Which in reality after you convert it correctly() is 2.5-3 bar on hot idle not 3-4, Hope this clears it up a bit

 

Ah I get you lol. I have a warning feature on my gauges, what should I set that to? 1.5bar or is that too low?

 

Best first to find out what your hot idle is. all motors vary a little as theres lots of factors involved. Id set it at half a bar below what is normal. Although the pressure may drop lower as you come to a stop. sometimes idle drops low for a split second before the idle control valve picks it up. If you get a warning at half a bar below normal idle then try again at .75 below etc etc

 

Here are the minimum specs. If you see pressure below these limits it's time to troubleshoot.
