Oil pressure


#1

What would make the oil pressure gauge fluctuate and go to zero? I already replaced the oil sending unit, and changed the oil and filter, whats left? maybe a bad gauge? Thanks sharon

Nobody can answer your question unless we know what type of vehicle you’re talking about.

Tester is mostly right. But the most obvious thing left is poor oil pressure pressure.

year, make, model, mileage please…

Could be a bad gauge. Could also be the engine is actually losing oil pressure and is grinding itself into scrap metal every time you run it.

The next thing is to install a manual pressure gauge on the engine and verify oil pressure as being good or bad. If you can’t do this yourself have it done at a local garage. Immediately.
