A simple way to do preventive maintenance is to check and change the oil on a regular basis. The steps are so easy that anyone can do them. No matter what, you can overfill your engine oil if you do it yourself. What comes next is the question.

Like not having enough oil, having too much oil is bad for your engine. A simple overfill can cost you a lot of money to fix and keep up.

Should I worry if I have an auto oil overfill?

If you put too much oil in, it could get on the crankshaft. Things are not going well. As the crankshaft turns quickly, it will mix air into the oil, making it foam up into a thick mass. If there is too much foam, the process of lubrication might stop.

The oil in your car could also get too hot or lose pressure. Your car’s oil pressure drops because the oil pump isn’t getting enough oil and can’t work as well as it should. The worst thing that could happen is that your car won’t have enough oil and will lock up.

When the engine warms up, the oil expands, so the oil reservoirs hold more oil. This might help make up for the mistake of putting too much oil in. But if there is too much oil, you can expect the following.

Consequences of overfilling your oil

So much force is needed to move all the parts in the engine. All of these moving parts need to be oiled all the time for them to work well. If the oil pressure changes, the following bad things can happen.

Complete and utter engine failure. It is the worst thing that could happen. Your engine breaks and can’t be fixed. Your car will need a new engine because of this.

Sustain engine damages. The engine rods of your car could get damaged. The rods could bend or leak, or the valves could fall apart.

Extensive engine damage from inconsistent oil pressure levels

Damaged spark plugs. When spark plugs don’t work, there are problems with the ignition. Spark plugs may need to be changed often.

It’s bad for your engine if oil gets into the catalytic converter.

How to check if you have overfilled your engine oil?

If you filled the oil yourself, it’s easy to tell if you have an oil overfill. But sometimes someone else does this service instead of you. You should always check the oil level in your engine.

Run the engine for 5 to 10 minutes to get the oil warm enough to check. Turn off the car’s engine and open the hood. Pull out the stick that you use to check the oil.

Use a clean, dry cloth to wipe the oil off the dipstick. Put the dipstick back in and then take it out again.

Now, check to see if the oil level is below the limit.

If you drive with too much oil in the engine, it will definitely break down. To avoid making such an expensive but avoidable mistake, you should watch out for the following signs.

Overfill symptoms

Your car is leaking oil. If you see oil stains under your car, that should be enough to tell you there’s something wrong with the engine. When your engine leaks oil, it breaks down. If not checked, it could cause the engine to break down.

The smell of your engine’s oil burning. At this point, something is likely burning or getting too hot. You need a quick answer to keep the engine from getting worse.

Black or white smoke comes out of the tailpipe of your car. When the extra oil becomes foam, it can catch fire. This is why your exhaust has white smoke coming out of it. You might think this is a coolant that is on fire. But no matter what, your car is in trouble and needs to be checked out. Don’t miss the white smoke sign.

The engine is making a strange sound. So many parts of the engine can move. If they don’t get enough oil, they will wear out and break. If one part is out of place, it can set off a chain of events that can cause the engine to blow.

The engine is putting out smoke. If the engine is making smoke, that’s a bad sign. Get your car checked out right away.

Do This If You Have Overfilled oil

The best thing to do when there is too much oil is to drain it. This can be done in two ways.

The modern choice, which is less messy

The old way, which is messy

Modern option

This is a simple, quick, and less messy choice. To get the extra oil out, you will need a pump that draws in air. Open the car’s hood and pull out the oil. You can do this through the hole in the cap or through the tube on the oil dipstick.

You can use either an automatic pump or a hand pump to get the extra oil out. This method leaves you clean. You don’t have to lift the hood of your car and crawl under it.

Conventional option

You’ll need a pan to catch the oil and a drive socket wrench. Raise your car so you can get under it. Find the plug for the oil.

Loosen the oil plug with your drive socket wrench until oil starts to drip into the pan. Don’t take out all of it, just a small amount.

Put the oil plug back on, then open the hood and look at the oil dipstick. Make sure there is just enough oil.

How to prevent an oil overfill from happening again

On the oil dipstick, keep the oil level between the minimum and maximum marks. There are many steps in the service process.

Make sure your car rests on an even platform. Pull up on the brake (set the parking brake). If it’s a car with a stick shift, put it in first gear. But leave the gear stick in park if you have an automatic car.

Turn off the engine.

When the oil is back in its sump is a good time to check it. If the engine was running, let it cool down for a few minutes.

Open the oil access cap and add oil until the level on the oil dipstick reaches the crosshatch pattern. Be careful not to put too much in. Let the oil drain back out as you slowly fill it up.

If the oil level is between the minimum and maximum marks, you don’t need to add more.

How much oil should you put in your car?

Every 5000 miles or six months, you should change your oil. Sometimes we need to get more supplies before we can hit these goals. This is important to know.

The amount of oil in your car is measured in quarts. The difference between the low mark and the high mark is one quart. This is all the information you need to figure out how much oil you need to refill your car.

To add a half-liter of oil to your car, for example, you should put a quarter of the oil on the dipstick. It will help keep the bag from getting too full.

The size of your car also affects how much oil it uses.

Your engine may use between 5 and 8 litres of oil, depending on how big it is. Small engines need less oil to make up for their smaller size.

5 litres of oil are needed for a car with a four-cylinder engine. An engine with six cylinders needs 6 litres of oil, while an engine with eight cylinders needs between 5 and 8 litres of oil.


Putting too much oil in your car is a big problem that can hurt your engine. The oil level should be between the top and bottom marks on the dipstick. Be careful not to go too far.

Make it a habit to check your oil level often, especially after you take your car out of the shop. They are people, so they can be wrong.

Don’t drive your car if it shows any of the signs above. Pull your car over to the side as soon as you notice that the oil level is too high and check the oil dipstick.

Some of the symptoms may be the same as those of other engine problems. Some of these signs could be related to other important parts of the engine. It’s always a good idea to get your car checked out regularly. Your car will keep running well as long as it gets regular service and repairs.
