I just changed my oil, and my oil gauge is reacting alot faster now seems like
I must of had 10w 30 ?
I just put in 5w 30
so my question is, what is your Z doing @ idle
and or your lowest psi mark
and your highest psi mark
and btw I tried looking for this online and only thing I could find is normal psi
@ idle was 12

 

not sure about at idle, but i can tell you with a fresh oil change, Castrol GTX 10w-30, My oil pressure is 60 psi in 6th gear at 60 mph when the car is warm.

 

Once hot, at idle the pressure is very low.

 

ah good to know..i was wondering for myself because it looks like its reading really low to me...

 

The pressure shouldn't change between 10w30 vs 5w30, once the normal operating temp has been achieved, assuming you have the exact same amount of oil in the engine. The "30" signifies viscosity after normal operating temp has been achieved. The "10" or "5" is the viscosity when the oil is cold. Hence, a 5w30 grade oil gets to cirrculating faster when it's cold, than the 10w30...

 

Thank you!
