Signs To Know When The Oil Level Is Too High

If you’re a driver, it’s important to check your car’s oil level regularly so you know when it needs to be changed. 99% of vehicles use dipsticks to do this, but there are a few cars that don’t use dipsticks at all and instead rely on a built-in oil sensor.

When the oil level is too high, over pressurizing the PCV (Positive Crankcase Ventilation) system can blow a seal, and you’ll have an oil leak because of it. It’s usually the weakest seal that goes when it does. This will lead to engine smoking and eventually engine failure. The vehicle may also lose power and stop running altogether. In extreme cases, the engine might also catch fire. So if you notice any of these signs, it’s essential that you take your car in for repairs as soon as possible.

On the other hand, too little? Well, you’ll end up frying your bearings. Literally pistons will be welded to the cylinder walls from heat build up from no oil.

To rectify these problems, if your oil level is low, add oil obviously. And if your oil level is too high:

  • Use a vacuum pump via the dipstick tube to suck it out
  • Or pull the drain plug from the oil pan and drain it all out
  • DO NOT PUT OIL THAT HAS BEEN DRAINED INTO A PAN BACK INTO THE ENGINE! a mere grain of sand can contaminate the oil and cause damage to the cylinder walls.
