Part of my commute consists of driving about 15 miles on a winding, two-lane mountain road. Within a couple of minutes of leaving the flatlands and getting onto this road, my oil pressure light comes on and stays on.
The first time it happened, I naturally pulled right over and turned off the engine. After waiting a few minutes, I started the engine again and the light stayed off. So I drove home.
The oil pressure gauge offers no corroboration; it hits the upper peg as soon as I start the engine, even on the initial start following an oil change when I *know* the oil takes ~7 seconds to make its way through the new filter, and stays there for the duration.
There are no secondary indications like low oil level or rising temperature, so I suspect it's either a short cir- cuit or the result of oil sloshing around in the pan.
Has anybody else seen this behavior?
