I am abit worried about my oil pressure reading...I run 5w40 semi synthetic oil of high quality and do oil and filter changes every 3-4K but I am worried that oil pressure is not brilliant. It hasnt missed a beat or tapped etc but the guage seems to be reading lower than i'd like. My readings are;

Cold Start in morning = 4.5 - 5Bar
40*C = 2.5Bar
60*C = 2Bar
80*C = 0.5 - 1Bar
100*C = 0.2 - 0.5 Bar

These are around about figures that i've spotted and are idle figures. When driving at around 2.500rpm figures are;

Cold Start = At the top 5.8Bar ish
40*C = 4Bar
60*C = 3Bar
80*C = 2.2Bar
100*C = 2Bar

When im flat out and oil temp is around 100*C, oil pressure doesnt seem to rise over 3Bar. Once again, no dodgy noise's at all and the engine sounds like a good one in my experience. No bottom end knock in the morning at all. What do you all think?
