It would be helpful to know what viscosity oil you are using. Assuming
you have the correct oil pressure switches, you may be getting the oil
too hot causing it too loose its viscosity. Also, make sure the engine
is not overfilled. The oil will stay cooler with the level between the
marks. The upper mark is not the engine oil full level, but the Maximum.

Subject: Oil pressure on a long trip

Hi all,

My '91 2.1l has been experiencing oil pressure issues as of late.  After
driving at highway speeds then slowing down in gear (like on a exit, or
in traffic), the oil light and buzzer go off.  I can make the problem go
away by revving the engine or downshifting.

Any ideas? Thanks.
Wade
