Read your pressure gauge
The oil pressure gauge relies on pressure senders. With the fluctuation of the oil pressure, the gauge’s internal resistance changes. The dashboard needle moves when the sender wires its signals to the gauge. If the engine is on but the gauge gets zero readings, there could be something wrong with the gauge, you might need to add some oil, or fix the oil pump. If you get high readings as you start the car, the pressure relief valve may be stuck. To keep the filter from bursting, turn off the engine.
Know low oil pressure when you see it
Smell any burning oil?
Anyone in their right mind would know that the smell of burning oil indicates that something bad is happening. In a car, it could mean there’s a leak, and that the oil started dripping on the hot metal. Stop the car and let it cool down. Next, check your oil level. Top it up if it’s too low and call a mechanic to spot the leak and fix it.
Look for the warning light
An obvious sign there is something wrong with your oil pressure is an activated warning light.
Listen carefully
An engine can get pretty noisy when it isn’t getting enough lubrication. Listen for any loud grinding or clunking sounds. They may indicate that the car’s rods are about to break, or that the engine is failing.
Mind the heat
When there is too much friction between the metal parts in the engine, temperatures rise and the engine might overheat. In that case, pull over right away and let the car cool down. If you can, have a mechanic come over to take a look. If it’s not an option, carefully drive to the nearest gas station carefully and only after the vehicle has cooled down completely.
