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*
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?
