Try a heavier oil (10w-30 or maybe even 20w-50 in warm weather) - may get tens of thousands of more miles out of it especially if oil pressure is OK at higher RPM - need very little pressure at idle to be acceptable and lubricate. S.Now would be a groovy time to upgrade to a mechanical oil pressure gauge. Just locate the stock sender at the back by the distributor, screw in a T-fitting, and then thread the stock switch and the line for your aftermarket gauge into that. Don't forget to wrap the threads with Teflon tape, too. 1.About a year ago I noticed that with the engine off but keyswitch to the first position, the oil pressure needle would be around 50 psi. When the motor was running it would fluctuate, but not much.
