XJS 4.0 Oil Pressure

Hi guys,
I'm just curious to find out if my engine oil pressure is "normal". Once warm, and at cruising speed the pressure is just over 4, and then when idling it drops to about 2.5. Is that normal? It fluctuates a little at idle....it that normal?
Hopefully I've got nothing to worry about.
Thanks
Paul

I was briefly confused about the oil pressure when I bought my XJS. I hadn't seen pressure values in Bar units since college.
1 bar = 14.5037738 pounds per square inch.
So 36 psi at idle doesn't seem so bad after all, eh?
I'll let the much better informed regulars offer an opinion on that pressure range. I will say that my pressure gauge is often pegged at 8+ bar off-idle, hovers around 3 bar (or less) at idle, and also fluctuates as you noted. I'm told the AJ6 has hellacious oil pressure by design.
