just wondering since the Z has an oil pressure gauge already, why the need for an aftermarket gauge? Is it just for a 2nd reading because it's really important?

Or is the stock oil pressure gauge not that accurate?

Is it wise to just scrap the stock gauge/sensor and just use aftermarket ones in place?


and is the temp gauge on the dash really just a water temp gauge, not an oil temp gauge? That's almost misleading - I've always thought it was oil temp

 

i would just rely on the stock one, it has good response and thats what matters. It appears to be accurate but even if its not totaly accurate, knowing your precise oil pressure doesnt help you much, its just nice to be able to compare your oil pressure under different circumstances. oil pressure can help tell you that your engine is up to temp and its safe to start giving it hell... if it reads lower then normal it can sometimes tell you if there is a leak... but what it does best is tell you if there is zero oil pressure and you already ruined your engine by looking at the gauge and pondering rather then shutting off the car.

oil pressure gauge is one gauge that i look at a lot... my stock ones seems consistent and response enough for me.

 

Most of the guys seem to want conformity in their dash so they change them all out to a single brand like HKS, Defi, etc.

 

It is just water temp. Not oil temp. For oil temp, you would have to get a new gauge and sensor.
