My oil pressure light often comes on briefly, especially when the engine is cold and when the idle is low.
2.0L engine, stock configuration, stock FI, 950-rpm idle, 4 quarts of 30-wt Castrol always. 114K miles, slight smoking, have not checked compression. 1/2 qt oil usage with every fill-up, I keep it topped up.
Are the oil pressure valves just gummed up? Or is my oil pump or oil pressure sender worn out?
Why is this and what can I do about it?

Install a new switch first and see if that is the problem. Usuallly the light comes on when hot not cold if the oil pressure is low.

Yup. And put 20w50 in it. The old Porsche "thing" about multi-grade oils is long gone, and you'll get better lubrication in both cold and hot weather with 20w50. The Cap'n

whats your oil temp look like?
hot oil is thin oil..... thinner oil is harder to make adequate pressure with

Doing the same with 20/50 for 30 years in mine.
