Low Oil Pressure Light 1982 eldorado
I recently bought a 1982 eldorado for my son and did a tune up and an oil change. After refilling with 4 qts 10w40 and 1 qt slick 50 low oil pressure light came on. One possible problem was the viscosity of the oil. Changed it to 20w50 but light still on. Engine is not knocking anyone have any suggestions?

Yes, change the Oil Press. Sensor (using original GM part) and get rid of Slick 50.
I don't go for miracle additives.
There could be other causes, but the Oil Press. Sensor is easiest and cheapest to change.
