Why does my oil pressure randomly drop?
The oil pressure gauge will usually drop when a few things could be happening. Either the motor is in fact low on oil, the oil pump could be failing or the oil pressure sending unit is not working properly and may be producing a faulty reading. Be sure the oil level reaches the “full” mark.
What causes an engine to lose oil pressure as it warms up?
You lose oil pressure when it warms up because the oil gets thinner. I always use to just run thicker oil. Its not your oil pump, you said it has good oil pressure when you first start it. As your bearings wear the clearance gets greater which will cause you eventually to lose oil pressure.
Why does my oil pressure drop when idle?
Low oil pressure at idle can be caused by low oil level, poor quality of oil, faulty pressure gauge, worn fuel pump, or by using the wrong type of oil.
What does it mean when your check engine light comes on after an oil change?
These lights can signal something serious or something as simple as a loose gas cap. One thing that won’t trigger a check engine light: a recent oil change that was done correctly.

What are the symptoms of a failing oil pump?
Here are some other recognizable symptoms or issues that may come about when your oil pump fails.
- Drop in oil pressure. Although you may be no automotive expert, the temperature gauge on your console will generally read warmer as a sign that an oil pump has failed.
- Abnormal loud noise from engine.
- Wrap up.
Is low oil pressure at idle OK?
Low oil pressure at idle only, will most often mean that the engine is low on oil. As more power is applied to the engine via acceleration, the pressure builds up inside the engine. Thereby causing the pressure to read as “normal”. A defective oil pump can also lead to low oil pressure at idle.
Will check engine light come on with low oil?
Low oil pressure: If your car is low on oil, it can cause your check engine light to go off. This is often shown in its own glowing light along with the check engine light on the dashboard. Overheating: If your car’s engine temperature is heating up, it can once again trigger the check engine light.
Will check engine light reset itself?
Your vehicle’s check engine light will will reset by itself once the issue or problem has been repaired; this is true for most models.

When does the low oil pressure warning light come on?
No VW van ever came from the factory with an oil pressure gauge or oil level indicator, just a low oil pressure warning light. When the engine is not running and there is no oil pressure at all, with the ignition switch in the ON position, the oil pressure warning light comes on.
What causes the oil pressure light to flash?
If there is enough oil in the engine to fill the oil filter plus around half a quart, the oil pressure will come up and stay up. The first time you go around a curve and the oil sloshes to one side in the engine, the oil pump will suck air instead of oil, the pressure will drop, and the light will flash, sometimes without being noticed.
What to do if your oil pressure is low?
Check engine light came on the low oil pressure light and DIC alarming to shut engine down. Shut engine down and restarted, oil pressure went back up to 40 and continued to drive until it happened again. I dumped a can of seafoam in the crankcase and ran it through for a while, changed the oil and filter and never had a problem since.
Why does the red light come on on a VW van?
Rather, the red light comes on when the oil PRESSURE drops too low as determined by an oil pressure switch installed on the engine. No VW van ever came from the factory with an oil pressure gauge or oil level indicator, just a low oil pressure warning light.
