Yesterday morning, car at NOT, sitting at light, oil light came on. Went off once I took off at the light, next light same thing. Stopped, checked oil level, full, Started truck and continued 3 miles to work, light did not come on again. Leaving work, oil light came on half way home, drove slow 4 miles to house. Engine runs fine. Started the truck today, ran for 10 minutes, no light. Truck is 2001 Ford Escape has 76K miles, oil changed regularly. What is causing the oil light to come on intermittently?

Maybe you have a faulty oil pressure switch which just stops working sometimes

notify dealer

Get the trouble code that is stored in the computer.This can get us in the right direction.

check whether that which was clicking fast is the main relay. If it is call the expert - electrician for help.

When a catalytic converter is coming apart on the inside, it can restrict air flow and power, and it usually happens or gets worse when the vehicle has been running long enough to generate a lot of heat. Once it cools down, the symptoms can completely go away until you begin to drive it again. It's one possibility.

the first thing to try is turning the heater upto full heat(a/c off)if the temp guage goes down THEN CHANGE THE THERMOSTAT...(hot oil,if too hot, is thinner than the normal sae rating so the oil pressure will be lower.otherwise no real problem.

PO455 is a large evaporative fuel leak. A bad fuel cap is ONE of the things that COULD be the problem. Fuel system cleaning only lightened your wallet. Reading your post is confusing. Did all this start AFTER the Valvoline Wallet Flushing? If so , they left something loose or disconnected. I would find a qualified repair shop to fix the problem, and if it has anything to do with what Valvoline did, make them pay the bill.

Sounds like your sending unit sensor - if it was your pump going out, your engine would be history by now. Rule of thumb, if your oil check light ever comes on, it's usually too late to remedy the problem. You have a major issue, but since you've obviousely drove it quite a bit since then and it still hasn't seized up, I'm guessing you're ok...for now. Since you took it to a shop and they said you're ok, I'm assuming they checked your level and visually checked for leaks and found nothing. Either, you've got somethijng partially blocking your pick-up tube for the pump which is in your oil pan, or a electrical issue with the sensor. I would start by having someone check the sensor out and go from there...good luck.

it sounds like the oil pressure is too high.have someone check for clogged blow-by hoses or connections.some blow-by connections have screens in them tha can become clogged with dust or oil deposits.also check for places where dust can enter into the engine,such as,air filters and air hoses that may be loose or damaged.
