On the oil gauge that comes factory does anyone know what the PSI is when looking at the N O R M A L gauge?? like what would the PSI be if the needle is pointing at R ?? and what is a heathy N O R M A L needle range on a 95 351??

ford specify in the workshop manual a minimum 40 psi at 2000rpm,what that equates to on the gauge i dont know,i assume if the needle drops below N,then you have gone below thw specified pressure.The only real way to find out is put in an after market mechanical pressure gauge,or see if you can borrow a master guage and compare it to and the factory gauge.
