Have just given my Z (1991) an oil change + flush and new filter and the oil pressure gauge now rises higher than I've ever seen it before (to about 7) when the engine is cold. It returns to normal when the engine has reached its usual running temperature. Is this the normal behaviour of the oil pressure gauge or has the oil change freed up some kind of blockage causing unusual gauge readings? Any advice welcome

do a search on oil pressure m8

zx's gauges are known to be suss, BUT usually its low readings

7 is normal for a half decent engine, so i'd say nothing to worry about

oil pressure will always be higher when cols as the oil thins slightly when warm but dont rely on standard z oil gauge they dont work properly

I answered in the other post........ :rolleyes:
