Oil Pressure

[viking]

just noticed my oil pressure gauge isnt going above 4kg/cm2 even when cold.

i have a new oil pump,

oil is quite black (5000km) can this hav such an effect on the oil pressure?

Higher viscosity oil will give a higher oil pressure. Usually old black oil (CHANGE IT!) is more viscous that the new stuff. You may be suffering from the ubiquitous Skyline blight - that of a stuffed oil pressure sender unit. Do a search & you should find boundless posts on the subject.
