Effect Of Excess Engine Oil In Your Car ?

What Happen When You Put Excess Engine Oil In Your Car

Excess engine oil in your car engine, can lead to over-pressurization of the engine causing oil leaks, increased engine wear and reduced engine performance.

Consequences Of Excess Engine Oil

When you add too much engine oil to your car’s engine it can lead to several problems.


Excess oil can cause foaming due to the crankshaft hitting the surface of the oil. Foamy oil loses its lubricating properties which can result in increased friction and wear on engine components.

2.Oil Leaks

Extra pressure from the excess oil can lead to oil leaks as it finds way to escape from seals and gaskets that might not be designed to handle such pressure.

3.Reduced Engine Performance

Engine moving parts can experience more drag and resistance due to excess oil leading to reduce engine efficiency and power output.

4.Catalytic Converter Damage

If the excess oil makes its way into the exhaust system, it can damage the catalytic converter leading to reduced emissions control and potential engine problems.

5.Increased Heat

Too much oil can lead to increased friction and heat in the engine which can contribute to overheating issues.

6.Loss Of Fuel Efficiency

Increased friction caused by excess oil can result in decreased fuel efficiency, as the engine has to work harder to overcome the resistance.

7.Oil Aeration

Excessive engine oil can cause air to mix with the oil reducing its ability to properly lubricate the engine components.

How To Fix Excess Engine Oil In You Car Situation

If you have added too much engine oil to your car’s engine, here what you can do to fix the situation.

1.Check Oil Level

Start by turning off the engine and allowing it to cool down for few minutes. Use the dipstick to check current oil level. This will give you an idea of how much excess oil you need to remove.

2.Drain Excess Oil

The most effective way to remove excess oil is to drain it. Locate the oil drain plug at the bottom of the oil pan found underneath the engine. Place a oil pan beneath the oil drain plug then carefully remove the drain plug to allow excess oil to drain out. Make sure you use appropriate tools and follow safety precautions.

3.Replace Drain Plug

After excess oil has been drained replace the drain plug and tighten it securely.

4.Replace Oil Filter

If your vehicle is due for an oil change, it good time to replace the oil filter as well.

5.Refill With Correct Amount Of Oil

Check your vehicle owner manual to determine the correct oil capacity for your engine. Add the appropriate amount of oil using a funnel to avoid oil spills.

6.Check Oil Level

After adding the correct amount of oil use dipstick to check the oil level once again to make sure it’s within the recommended level.

7.Dispose Of Excess Oil Properly

Used engine oil is considered hazardous waste. Store the excess oil in a container and dispose of it at a recycling or disposal center that accepts used engine oil.


It’s best to consult a professional mechanic to address the issue properly and avoid potential damage to your vehicle engine.
