Oil pressure too high?

[high52kojak]

Noticed today that my oil pressure is at 60 psi when at idle with the engine warm and up to 80 under load? Is this a normal figure or could there be some other reason, faulty gauge etc?

[Gazzab]

Could be that there is something affecting the oil pressure relief spring. My first Cerb had an old bit of spring bodged in by prev owner to keep the oil pressure artifically high.

[high52kojak]

What sort of pressures was it showing and what is a healthy number?

Mine the same as this - and i have wondered if it sounded too high myself. Seems to run ok though.

Mines a bit overfull on oil level after the last service, i'm reliably informed this wont increase the oil pressure though so i cant be bothered to drain some out.

Mine goes ok but i am pretty sure it has recently upped to those figures, seems a bit wierd to me. Looks like I might have to have a look at the pressure valve thingy

hi before my engine rebuilt pressure was between 40-60 psi. Now 55-60 at idle and 70-80 when driven.

I was told by APM that 60-80 is the right pressure

[high52kojak]

Thats quite reassuring, suppose its better to be high rather than low.

Since my rebuild I hit 90 on full chat (fully warmed as well). APM said that's the top limit.

Exactly the same readings as mine.

[Scrooloose]

Same as mine too

Hmmm, interesting. My oil pressure is a rock steady 50-60 until warm, then it moves to 40-50. When very hot sitting in traffic it will sit at 30 but when I start moving it rises to about 40-45 again.

I was told this is the right pressure.

So, 60-80 and 30-45 are both the right pressure for a hot engine???

Out of interest what oil are you using? I used to run 0w40 until the last service when I was told I shouldn't be using that anymore (even though the car hardly uses oil) and now use 5w40.

i run chevron 5w-40 at the moment but have also used 15-40 oil pressure readings are the same

As low as 30 when very hot is fine, but you wouldn't really want it to be much lower.

60+ at hot idle I think is on the high side, I bet those figures would drop in summer.

If it's not using any oil then I'd go for 10W 50 fully synth, alternatively go for a 15W 50, these are both slightly thicker oils than you are currently using and should see your oil pressure increase.

Yep, I agree. The times it drops to 30 is usually in the summer months when queuing in traffic for 1/2 an hour or more. Then it just sits at 30 while the temp cycles around 105-95-105-95 in 5 minute intervals.

Thanks - I will mention this at the next service/oil change.

Now if only I could find an me0154 window/door control unit...
