Hi

I have down a search but not really found the info I need.

I have an 03 Sti which has just had its 5 year service and cam belt change at 39k miles.

Prior to the service the car was running with a semi-synth 10/40 oil which was put in by the Subaru garage from where I purchased the car prior to me buying it.

Now the car as 15/30 Motul Fully synth oil as recommended by numerous people on here.
I did expect a raise in oil pressure due to the different viscosity rating of the new oil.

At cold idle i am seeing 97 psi rising to 107psi cold when driving (keeping below 3k rpm). Once warm, oil temp 85 degrees, it idles as 45 psi and rises into the 90s when being driven.
All measurements taken from PSi3 monitor.

Is this correct?

Many thanks
steve
