20 psi at idle when the car is warm is perfectly fine. Oil pressure will always be higher at idle on a cold engine because the oil is thicker when cold. As long as the pressure goes up with rpms you should are dine. You should be putting out around 60-80 psi by 2000 rpms and above.

My car idles around 20-25 psi when warm

if you're not reading normal oil pressure during the higher RPM range
you should do a cylinder compression check... might need new rings
