My oil pressure is going away.....

If that has a high volume (HV) pump you should have much higher pressures. If it was me I'd have it checked with a mechanical diagnostic oil pressure gage. The hot psi should be at least 25, and the pressure should immediately rise to beyond 70psi cold, and at least 70psi hot at 2500. If there is a problem, catching it before it eats the expensive hard parts is the best solution.
