hi everyone, just bought my first 300zx on friday, its a 93 twin turbo fairlady, runs really nice although iv noticed the oil pressure seems very high, its measured in kg/cm and it steadily goes up to between 9 and 10 the gauge ends at 11 so im quite worried about it, iv checked the oil level which is fine, just been serviced, its had a ecu remap and bigger injectors put in, but now im thinking about not driving it incase i do any damage, any ideas what it could be? everything else seems fine and it got me back over 200 miles no problem. thanks very much.

The oil psessure gauge on the dish are often wrong, mine reads low all the time. I would do an oil and filter change first and then see

it was only serviced 400 miles ago, what could be the cause of high oil pressure? am hoping it is just the gauge that is wrong, you would think if it was something serious it would hav gone when i drove it home?

think i might hav sussed it, i hav after market gauges greddy oil pressure oil temp and boost which all hav a memory button which was on, wen i pressed it of it went down to 3 while on idle and goes up accordingly when i rev it, so hopefully panic over:)
