All,

My 84 runs great and gets 25mpg hwy.. I need to know the best oil pressure for this..

My car runs around 50-60 on hwy on oil pressure.. idling it can get down to 30 is this abnormal?

Sounds normal to me 84, with the engine hot, my 85 hovers at 51-52 at hwy speeds, and around 32-33 psi at idle.
