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? |

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
