1995 Ford Mustang After I've been driving for about forty five minutes over 75 mph, my oil pressure goes down. If I reduce my speed to about 55 mph, the pressure goes back up. It got better after I changed the oil, but it still does this occasionally. I've heard of running gas through to get the clog out. Is there another way to get the clog out if that is even the problem?
Sludge deposits may be your problem. They restrict the oil returns in the engine "holding" oil up in the engine and away from the oil pickup. Try several oil and filter changes at shorter than normal intervals with the engine at normal temperature. We do not recommend running gas through the engine.
