Many old/high mileage vehicles that have this issue have changed to an oil with a higher viscosity or used an additive

At this point you've got few options .... STP (do they still make that?) or rebuild.///interesting article at /////// http://www.germanformula.com/5-causes-of-low-engine-oil- pressure/ \\\\\\ The oil filters play an important role in maintaining oil pressure. Should the filter get clogged it will reduce the pressure. The pressure relief valve of an oil filter is there to make sure the pressure does not get too high. However, if the relief valve is damaged, then oil will pass more freely in the engine, and that will reduce pressure.
