I've just fitted a Oil Pressure Guage. Compare reading with my friend who has a Evo 6. His reading is around 1 kg/cm^3 when idle (already warm up) but mine is only around 0.4 - 0.5 kg/cm^3. I was wondering whether the mechanic who fitted the guage fitted it wrongly??

Do u use the same oil as your friend ?
Also , by the sound of yr nickname u have a Evo V , how many miles do u have on this compared 2 yr friends VI.

It cud b a fault tho , even with yr engine Even a faulty gauge , have yr garage do an oil pressure check with a master or calibrated gauge 2 check the accuracy of the car gauge.
Check the installation of the gauge , but there is not much 2 do wrong here.

I have seen that problem in other cars and the reason was the oil, the car with a low oil presure was using a bad quality oil.

I got a Defi oil pressure gauge too and it reads 6 kg/cm on first start of the day. 1 kg/cm when fully warmed up sitting at a red light. Does this seem a little on the low side? My 1992 Porsche 968 has higher pressure at idle. Why is the Evo pressure so low at idle?

BTW: I'm using Castrol RS 10W-60 oil and mileage is 14,000 KM (8700 miles).

Will changing to a thincker oil (ie 15W-50 Mobil 1) give me better pressure?

Cheers!

Service spec is 0.78 bar or 11.47 psi minimum , at idle with an oil temp of 75-90 c.
