Oil Pressure issues

[Thuppu]

I checked my aan oil pressure with a mechanical gauge and it showed about 0,5 bar more on high rpm's than the stock gauge. Idle was almost identical, maybe 0,1-0,2 bar more...

OEM was 6-7psi lower

We seems to have almost the same results. I used a industrial gauge to check the pressure:

good info there.
thanks

Painfully I can see myself buying all RT sensors for mine, I only have two ( Fuel pressure and Oil temp ) but after your findings I think I'll maybe invest in a oil pressure one.

Painful!

Thats a lot !

Can't fault the accuracy of the RT stuff by the sounds of it then.

No you cant James, I am not saying every ones sensors are this far out but they are 20 ish years old.....

what was the reading on the dash 2 and the original one?

[terrybullwon]

Can't believe this thread is still going on! The aux gauges are really just for quick reference / show, they are not accurate at all!
Check it with a proper gauge if you are worried. If you had really low oil pressure your top end would make a racket you would know about it!

Confirmed.

Race technologies sensor with Dash 2 read different to stock so i got a mechanical gauge and tested it

[A80Avant]

some did check with a proper gauge. so we are trying to understand if the readings are normal for these engines or the rumor of 1.8bar at idle is a misunderstanding

Just to add to this thread, I'm seeing 1-1.2bar oil pressure on hot idle as well. Normally it's about 1.4bar when up to temp, and it's making about 4.5+ bar at 3000+ so I'm not really concerned. My idle is set to 720rpm.

Our standard ABY's shown that since we bought it in 2002 (and it's still going strong), the RallyRep's AAN does very similar too...

10v's tend to make stronger oil pressure at idle, but even that's below 3 bar hot.

[A80Avant]

That's reassuring Ross as your engine is also fully rebuilt!

The engine has 1,100 miles on it and the oil pump is refurbished. I can't remember what it was before the change but I figure that with a new filter and everything cleaned out perhaps there's a small drop as a result.

I've just changed from 10W-40 mineral to 10W-50 Titan Pro S and haven't noticed a real change in pressure...

Something I'll keep an eye on, especially when I get some sustained thrashing, but it's well above the 0.3bar idle / 1.8bar 2000rpm warning levels and from reading this thread seems pretty normal.

Well.. nope!

Engine oil pressure too low (below 1.8bar above 2000rpm or below 0.3bar at idle) - Should you ever be unlucky enough to see this, STOP and switch off engine immediately. It is just possible that a very low oil level may cause this condition but a tow truck is gonna be the least expensive way home.
