Why does my oil light flash when I start my car?
When the oil light on your dashboard comes on, it might mean your vehicle has low oil pressure. This drop in oil pressure could be a sign of a few things: you are low on oil, your oil is dirty, or you have an oil leak.
What does it mean when your oil light is blinking on and off?
If the oil light flickers on and off while the vehicle is stopped or at an idle, there may be a problem with the oil sensor or the pressure is too low. At the very least, the engine should have 5 PSI when not moving. If the light flickers while the vehicle is in motion, the oil levels may be too low.
What causes the oil light to blink?
Why might your warning indicator flash? A low oil level is the most likely cause, but you’ve checked that. The next most likely cause could be worn engine bearings, which allow the oil pump’s volume to squirt more out of places it would normally be retained.
Can cold weather make your oil light come on?
Cold Weather Slows the Flow of Oil When you start your vehicle, its oil pump forces oil under pressure through the oil filter, main bearings and other parts of the engine. During cold weather, an engine’s motor oil becomes thicker. and must work harder to generate power that makes the engine turn.
Can I drive with oil light on?
If you’re driving along and your oil warning light comes on, take it very seriously. This indicates that your car may be unsafe to drive. Your auto’s engine has lost oil pressure, or the oil level is too low. When the warning light comes on, pull over as soon as possible and shut off the engine.
Is cold oil bad for your car?
Myth – It’s a good practice to let my car idle (warm) on cold days. Fact – The only reason to idle a car is to circulate the engine oil. When your car engine is cold, the fuel injectors send more fuel through the system. As the engine warms, it needs less fuel to run efficiently.
What happens when oil pressure is low?
If the pressure drops to the point where oil is no longer flowing freely around all the engine’s moving parts, unlubricated metal surfaces will come into contact. This results in friction, warping, seals breaking, and some other issues. In short, it’s a quick way to ruin an engine.
Is it OK to drive with oil light on?
Why is the oil light blinking on and off?
I think the problem may be with either the oil pump and any pressure relief valve, or the oil pressure gauge and/or wiring. What I would do is with the engine idling, wiggle the wire plug at the oil pressure switch and see if the light does flicker off and on, so you may need a helper.
When does the oil pressure light come on?
Oil pressure light flashes in the morning when the engine is cold. If I turn the car right back off then right back on, the light stays off. The car is running fine, just had an oil change 200 miles ago.

There are actually two scenarios when the oil pressure light is on your dashboard. One of them is that it is a false alarm and there is a problem with the oil pressure sensor or the wirings to it. The other scenario is that your engine actually has low oil pressure, which is a little bit more serious.
Why is the oil pressure on my car so low?
This removes most of the impurities. The oil then flows through the crankshaft and the head of the car engine. However, if any of these oil passages are clogged, it may cause the oil not to reach the oil pressure sensor, and it will cause the oil pressure to become low.
