has anyone ever notice when your car is cold and when its warm how fast the oil pressure should come up ?


and how far should the needle come up on the temp guage what is normal and what is not


and are the two related ?

 

Year and model?

Oil pressure should be instant as soon as the car is started. It will be higher when cold.

After it warms up, you should be seeing about 30 PSI at idle and above 50 PSI at 3000 RPM.

Temp gauge depends on the car.

 

Not sure if I understand your question completely. But the viscosity rating of your oil and ambient temps make a difference. Rotarys tend to have fuel dilution to some degree over time, so how long since the last oil change can also influence things. And at least on the FD there will be some difference if you've removed the thermopellet. On mine it was generally higher, especially at cold start up.

 

86 gxl and i have been having issues with my start up after driving the car for a while especially when i drive it hard so , what i do notice is how slow my pressure guage on my oil goes up when i have these issues compared to when i cold start it in the morning and the needle just goes up to 60 psi

 

Yeah man the oil preasure should be atleast 50psi idle and when hot be around min 40psi preasure.

derpends how old ya engine oil is to,iff its new should be high 60psi.

Ya temp should be half way on old rx7 like s1 s2 s3.

And the new cars like yours should be 1/3 so just under half way,iff its in the red you might have other issues,dont drive ya car iff it goes into the red.

But iff your driveing ya car very hard then the temp is goona go up a fair bit.

 

Um, no, it shouldn't. Factory spec says that anything between 15 PSI and 30 PSI is acceptable at idle. Pressure will be higher when the engine is cold.


No. S4s run at about 1/4 on the gauge. Half way is hotter than normal.
