Why is my oil light coming on then off?
If the oil level on the disstick is close to normal then it could be a bad oil pump, sludge somewhere in the motor, or a clogged oil pick up screen in the sump area of the oil pan. Sometimes the AC compressor locks up. Since your oil light was coming on the AC is likely not the problem in this instance but it should be checked first to rule it out.
When does the oil warning light come on?
If the oil warning light flickers even when the engine is not hot, then the problem is not about the viscosity of the oil. Now observe if the oil warning light flickers only when the engine idling. For the normal operation conditions, the oil change is every 6 months or every distance of 5,000 km whichever comes first for diesel engines.
What to do when your oil light goes off in your car?
Start the engine, and see if the oil light is still on. If the oil light stays off, it means your engine was low on oil. You will need to assess where the oil went, but can safely drive the vehicle as long as the oil doesn’t leak out of the engine too quickly. If the oil light comes back on, shut the engine back down.
What to do when oil pressure light comes on?
If an oil pressure light comes on the first thing to check is the oil level on the dipstick. If the oil level is OK, then a bad oil pump is suspect and the car shouldn’t be driven until the reason for the low oil pressure is found and corrected.

Why does the oil light come on when I come to a stop?
This sounds like you have a bearing clearance that is excessive enough to cause the oil pressure at low engine rpms (when the oil pump’s output is lowest) to fall below the oil sending unit pressure threshold for when the light turns on. That threshold is often in the 7 psi range. I would try missleman’s suggestion for a new sending unit first.
What causes the low oil pressure warning light to come on?
Below are the top 5 causes of a low oil pressure warning light coming on. The oil pump creates the pressure in which the oil needs to keep flowing steadily in the engine. Obviously, if you have a bad oil pump which fails at its job, then you will have low oil pressure in your engine. As a result, the low oil pressure warning light will illuminate.
When does the Check Engine light come on?
4. Check Engine Light comes on. If the oil level sensor is working correctly, it will trigger the oil light to come on your car, truck or SUV when the oil level is low. It’s also common for it to trigger the check engine light if the sensor is damaged or faulty in any way.
What happens if your oil level is low?
If the oil is low, it will trigger a warning light indicator on the dashboard, or will illuminate the check engine light. However, since it’s exposed to intense heat and harsh conditions, it can wear out or send faulty data to the engine control unit (ECU).
