I'm thinking that by 180F, the oil thins enough for the sensor to register
an oil pressure which is too low. What viscosity oil are you using? It
could be a sign of a failing oil pump, me thinks.

Ever seen an oil pump? They are unbelievably simple and unlikely to fail
before an oil pressure sensor - which is almost certainly got clogged the
first time the car was heated up after storage.

I'd change the oil, filter and pressure sensor and call it a day...

Actually, oil pumps aren't that unlikely to fail under certain conditions -
sludged up 1.8T engines come to mind. Depending on what maintenance and
what oil was used on that 2.8, it's a possibility as well.

Sure. I'd start with that and see what happens. Then, worry about the more
expensive stuff.

What I said was:

'Ever seen an oil pump? They are unbelievably simple and unlikely to fail
before a pressure sensor."
