5 Symptoms of Oil Level is Too High in Your Car

Oil is always a good thing for an internal combustion engine to have flowing inside of it. The size of a car engine determines how much oil it always needs. The average car engine needs anywhere from 5 quarts to 8 quarts of oil. Smaller engines in smaller cars need less than 5 quarts of oil. It all depends on how many cylinders exist within the engine.

For instance, 8 quarts of oil will satisfy an eight-cylinder engine, while 6 quarts of oil will satisfy a six-cylinder engine. If you have a four-cylinder engine, then you can use 4 or 5 quarts, depending on what the manufacturer recommends. But you get the idea of how more cylinders means more oil needed.

Oil is what keeps engines cooled down. Since they have moving parts which rub together, the oil prevents these parts from causing too much friction. This, in turn, reduces the amount of heat generated by the engine.

Naturally, you would assume that an abundance of oil is necessary to keep your engine extra cool. After all, oil can also help clean debris particles and other contaminants off your engine’s components as well. So, does an excessive amount of oil allow it to do a better job of lubricating and cleaning the engine?

The simple answer is no. A high level of oil in your car engine will diminish the quality of the lubricating and cleaning that it is supposed to do. There are several noticeable symptoms which will come up and cause problems with the engine performance and other components of your car.

5 Common Symptoms

Below are the top 5 symptoms of a high oil level in your car.

1) Oil Leakage

There are gaskets which prevent oil from leaking out of the engine. But if there are excessive levels of oil in the engine, they won’t be able to contain it. Eventually, the oil will leak out through the gaskets and actually reduce the oil levels in your engine. Therefore, an abundance of oil could have the opposite effect and cause your engine components to become less lubricated because of a lack of oil.

2) Foamy Oil

When you have too much oil in the engine, outside air mixes with the oil as the crankshaft rotates. You cannot have air mixing with oil because it will cause the oil to become extra frothy and foamy. Foam is the result of air bubbles forming in the oil after the air makes contact. Then your engine will have foamy oil running through it. As a result, the lubrication properties of the oil are diminished considerably.

3) Overheated Engine

This is a continuation of the previous symptoms. If there is oil leakage or foamy oil and your running engine is not getting cooled down enough, then it will start to generate too much heat. If the heat gets out of control, it could cause your engine to overheat. You can check on this by looking at the temperature gauge on your dashboard. If you continue to see the needle moving more toward the red zone, then you know there is a problem.

4) Contaminated Oil

Oil cannot circulate properly in the engine when there is too much of it in there. Whenever oil circulates poorly, it does a terrible job of cleaning away contaminants and debris in the engine. Because of this, those contaminants will build up in the oil and cause problems for the engine. You’ll quickly notice the engine won’t run as smoothly as it used to.

5) Engine Warning Light

In continuation of the previous symptom, your Check Engine warning light will illuminate in the event of oil contamination issues. Since contaminated oil degrades the functionality of the engine, your car’s computer will immediately warn you about a problem with the engine by illuminating the engine warning light.
