When you change your car’s engine oil multiple times, there are chances that you might accidentally overfill it.
This overfilling of engine oil into your car may lead to cause severe damage to your engine parts, and at last, your Engine will lockdown. To get rid of this issue, you must fill the engine oil properly into your car, but in case if it gets overfilled, you should check to drain the excessive engine oil from your car’s oil pan.
Overfilling the engine oil in your car leads to serious problems for the health of your vehicle. Though oil is considered as an important aspect for the vehicle’s functioning, having too much lubricant oil in your vehicle can essentially lead to some serious effects on the Engine, sometimes it may collapse valve pipes, spark plug fouling and many more.
Understanding the issue properly can appropriately help you to increase your vehicle life.
So now let’s have a look at the effects of Overfilling Engine oil which may lead to some serious issues.
What Happens if You Overfill Engine Oil?
Oil reservoirs in a vehicle are specially designed so that they can hold a little bit of extra oil for compensating the expansion of fluid in warmer situations. Apart from this, an oil reservoir helps in the prevention of additional damage to the vehicle engine if the overfilling of the oil is done in the Engine.
Overfilling Engine Oil by 1/2 Quart will not lead to cause any kind of damage to the Engine of your vehicle, but overfilling the oil into the Engine will cause serious concerns to your Engine.
When excessive oil is poured into the oil reservoir of the Engine, this excessive oil could easily go into the crankshaft when it spins. The engine oil gets mixed with aerates and air, which is also called ‘foaming.’
This combination of air and oil leads to the reduction of oil pressure because the oil pump is not capable of maintaining pumping the oil efficiently.
1. Overfilling Engine Oil Symptoms
This problem is mainly faced at that time if you have changed your vehicle’s engine oil by yourself, and accidentally you have added more oil, which leads to overfilling if engine oil in your vehicle. So, if this is the case, then you should know about the Overfilled Oil Symptoms. You should know about the basic symptoms that will happen so that you can prevent your vehicle from severe damage -:
Common signs of engine oil overfill include:
- You will come to observe regular oil leakage from your car.
- You will odor smell of ignited engine oil, and sometimes you could observe black exhaust from the tailpipe of the vehicle.
- Sometimes you might observe that smoke is coming out from the engine compartment.
- May observe strange noises that are coming out from the Engine.
How to Remove Overfilled Engine Oil
There are various ways through which you can remove overfilled engine oil from your vehicle. But here we will be talking about two common ways through which you can easily use to remove the excessive engine oil.
For draining excessive oils from your vehicle engine, you will require the following tools which are suction pipe, socket wrench, drain pan, and the main thing you should know where oil plug is situated in your vehicle. Let’s start the procedure of taking out excessive engine oil from your vehicle
If you consider that you have just added up too much oil in your car’s engine, then the perfect way to drain that excessive oil is from the bottom of the car.
After this follow these simple procedures
- Firstly you need to crawl under your car at that position where your car’s oil plug is situated. Once you have reached the prescribed location, then you need to place the drain pan under the oil plug so that you can collect the oil.
- Once the drain pan is placed appropriately, now you can lose the oil plug with the help of a socket wrench. One thing to remember that you should not lose it very fast because loosening it quickly may lead to oil plug come out and this will lead to wastage of your whole engine oil.
- After loosening the oil plug slowly small amount of oil with the continuous flow will come out from the oil plug let it flow. And after that, you can check the oil level with the dipstick. If the oil goes to normal then you can tighten the oil plug appropriately so that there should be no leakage when you drive your vehicle.
2. Suction Pipe Method:
This is considered one of the simplest and easiest ways to drain the excess oil from the oil reservoir of the Engine. In this method, you need to have a suction pipe and drain pan. The process which needs to be followed is that you need to put the sanction pipe at the place where you put the dipstick to check the oil level.
Once suction pipe, if placed appropriately, you can suck once, and oil will start coming out from that suction pipe. This process is simple, but the major drawback of this process is that this process is quite time consuming and requires a good amount of time for draining excessive oil.
Can You Drive a Car with Overfilled Oil?
Engine Oil acts as a lubricant in the Engine of a vehicle. But, the question which comes into mind is that can we drive a car with overfilled engine oil and the answer to the question is No. You should drive your car with excessive oil because overfilling engine oil will create problems for your car engine.
A vehicle should have an adequate amount of oil so that the Engine can give the best performance. If the quantity of oil is quite low than the required amount, then the lubrication of the Engine will not be done properly, and this may lead to engine seizer.
The same is the effect of having excessive oil as this will lead oil to whip into foam by interlinking with crankshaft and leakages into other parts which might result in building low oil pressure.
So both the outcomes can lead to some serious issues for the Engine, and you might have to pay a huge amount to get your car repaired. You can drive your car for a smaller run like you can reach out to any automobile repairing company or any mechanic.
So that they can drain excess oil from your car but you should not drive your car for longer run as excessive oil can lead to some serious troubles for the car.
#1 – White Exhaust Issue
With excessive oil in your vehicle, you might observe the white exhaust smoke which is coming out from the tail. This white smoke is an indication that the Engine is functioning, but it may not have oil.
This is due to the overflowing churning process which leads to generating foam and it might start to burn which will lead to producing white smoke. This is also called an antifreeze burning process.
#2 – Oil Pressure Not Maintained
When you do overfill of engine oil, it fills the crankshaft of your car, which leads to aerate the oil and turns out into foam. This is all due to the high rotational process of the crankshaft.
This foamy oil does not lubricate your car appropriately and it will lead to halting the supply of oil flowing, which leads to overheating of your oil and completely lost the oil pressure. Due to this process, there is a shortage of oil for the lubrication of the Engine, and this will lead to locking up the Engine of your vehicle.
Can Too Much Oil Damage Your Engine?
In a simple way, the answer to this question is yes. There are various things that occur if the overfilling of the oil is within your vehicle. Your car engine mainly depends upon the on reliable oil pressure, which helps in rotating the parts quite smoothly, and friction does not have severe effects on engine parts.
So sometimes effects of putting too much oil in Engine may result in severe damage of the Engine due to adequate change in oil pressure and the whole lubrication process can lead to
- This might lead to damage in Engines such as collapsed valve pipes or bent rods in the Engine of the vehicle.
- It may lead to catastrophic engine failure; in that case, the whole Engine gets too much damage that it cannot be repaired and needs to be completely replaced.
- High wear and tear of Engine because Engine will face inconsistent oil pressure while running.
- Fouling in Spark Plug which results in the replacement of spark plug regularly.
The effects of too much oil in the engine will lead to some serious issues, and sometimes, it may lead to damage to your vehicle engine. So, you should maintain an adequate amount of oil in the oil reservoir so that you do not face any serious issues.
Always check your oil level at regular intervals, especially at that time when you have to get your car serviced.
