Oil light comes on idle or stopping at red light after 30 minutes warm up the engine. I have changed oil sensor, oil, and oil pumps. Is there any feedback to resolve the problem? Can I increase the idle RPM? ---

Take the vehicle to a good mechanic. Have the oil pressure tested with a calibrated oil pressure gauge. If it reads low then it’s time for an engine rebuild or a new engine. Increasing the idle speed may make the oil light go out but the engine is doomed if the oil pressure is low. ---

Model year? Mileage? Engines need 10 PSI for every 1000 RPM of engine speed to survive. Sometimes high-mileage engines can benefit from using 10/40 or even 20/50 oil in their later years… Oil pressure at idle is not a critical concern as long as no knocking sounds are detected… ---

With all the work, got to heavier oil weight in a Dodge Intrepid and hope it goes off. The car likely does not have enough value justify major engine work.
