70 to 80 mph and if take foot off accelerator and then depress gas pedal the pressure
gauge responds but the length of time varies. When oil level is checked it is fine and the
dashboard "dummy" light never has illuminated. Any ideas on cause and remedy

That is telling you your oil pump is not pumping no oil pressure but since it's not tapping or making any kind of noise at 70 - 80 mph I would say you have a bad oil pressure gauge or sensor they goes to gauge.

I would get it to a specialist before driving it again. If the oil pump is going bad, you could end up with a huge engine rebuild bill


I would have it towed to an authorized mechanic. Don't take chances. Things to remember: Always check the oil at full operating temperature? When you start the car, is there oil pressure? Does the engine rattle when it first starts?


Oil is the life blood of you vehicle. Bouncing pressure on the gauge and low readings can occur for a host of reasons. Bad sensors, older engines, etc. If you warning light is coming on under speed I would get the problem professionally diagnosed and fix immediately .
