How Long Can I Run My Car With Too Much Oil? (My Honest Take)

Excessive motor oil within an engine can lead to significant issues and concerns for vehicle performance and longevity.

Many car owners may wonder, “how long can I run my car with too much oil?” 

This article aims to delve into the repercussions of overfilled engine oil, the risks it harbors, and the preventive measures that can be taken to avoid such situations.

By understanding the consequences of excessive oil and knowing when to take action, you can ensure your vehicle’s proper functioning and maintenance, prolonging its life while maintaining optimal performance.


How long can I run my car with too much oil?

Running your vehicle with too much oil is risky, and you should aim to correct it as soon as possible. While it may seem minor, an overfilled engine can lead to several problems, including engine damage.

Too much engine oil creates increased pressure, pushing oil into the crankshaft area, where air bubbles get mixed in—a phenomenon known as frothing. This frothy oil does not lubricate effectively, leading to increased friction and heat, which can cause significant engine damage.

Moreover, excess oil can reach the crankshaft and cause it to dip into the oil in the bottom of the engine, whipping it into a foam, reducing oil pressure, potentially causing a breakdown, or even complete engine failure.

To avoid these issues, I would advise not to drive your car with too much oil and to drain the excess as soon as possible. Consult with your car mechanic immediately to rectify the situation.

Is it OK to drive a car with too much oil?

While driving a car with too much oil may be possible, doing so could lead to serious long-term damage. Overfilled engine oil can cause various issues from minor discomfort to catastrophic engine damage.

Excess oil in the engine can generate an overly high level of pressure inside the engine. This heightened pressure can push the extra oil into areas where it should not be, such as the crankshaft, causing it to dip into the oil, creating a foam.

This frothy oil reduces its ability to lubricate internal engine parts appropriately, which can lead to increased friction, heat generation, and ultimately engine damage.

Overfilled oil could also lead to leakage, which might damage other components under the hood. It’s highly recommended not to drive the vehicle until the excess oil has been drained or removed. Consult with a professional mechanic or service center to correct the oil levels and maintain the health of your engine.

Can I drive a short distance with too much oil in my car?

Technically, you can drive a short distance with too much oil in your car. However, it’s not advised. Overfilling your engine with oil can cause significant damage, even over small distances.

When the oil levels in your car are too high, it can result in the oil becoming aerated and mixed with air, turning it into a frothy consistency. This frothy oil can’t lubricate the engine parts effectively, causing increased friction, high temperatures, and possible engine damage.

In addition, excess oil may seep into important components, such as the crankcase, where it can create excessive pressure. This pressure can lead to leaks or cause the oil seals or gaskets to blow out.

Although the risk might be less over a short distance, the potential for severe and costly damage to your vehicle still exists. It’s recommended to rectify the problem immediately by draining the excess oil or seeking help from a professional mechanic, even if your journey is short.

How far can you drive on overfilled oil?

The range of driving distances on overfilled oil can vary greatly, but in any case, it’s not recommendable due to potential engine damage. Too much oil in the engine can whip up into a frothy mixture inefficiently lubricating and cooling the engine’s components.

This frothy oil can increase friction and higher temperatures, possibly causing severe engine damage. Furthermore, excess oil could invade critical areas like the crankcase, leading to excessive pressure that may result in leaks, or blowout of oil seals or gaskets.

Distance-wise, damage could occur after just a few miles or take longer depending on the vehicle, how much oil has been overfilled, and the driving conditions. However, any distance driven could potentially cause irreversible damage to the engine.

In conclusion, if your vehicle is overfilled with oil, it’s best to drain the extra oil to the correct level or get it serviced by a professional mechanic as soon as possible, regardless of the distance you drive.

Is it worse to have too much or too little oil in car?

Both situations – having too much or too little oil in your car – can seriously damage your vehicle’s engine.

When there’s too little oil, there’s not enough lubrication between the engine components. This lack of lubrication leads to increased friction and heat, which can cause the engine to wear prematurely, seize up, or even break down completely.

On the other hand, too much oil can create excessive pressure within the engine. This pressure can cause the oil to foam, which affects its ability to lubricate, leading to similar issues as a lack of oil. Overfilled oil can also cause leaks, blow gaskets, damage seals, or force oil into areas of the engine where it shouldn’t be.

Both conditions are harmful, but an overfilled oil situation can be rectified more easily (by draining the excess oil). It is important to regularly check and maintain the correct oil level to ensure your vehicle’s smooth running and longevity.

Will overfilled oil burn off?

While cars can burn off a minimal amount of excess oil over time through normal operation, it’s not a reliable or recommended solution for significantly overfilled engines. Engines are not designed to burn off excess oil intentionally.

If there is too much oil, the extra oil may get whipped into a froth, making it ineffective as a lubricant. Moreover, the excess oil might reach the pistons and enter the combustion chamber, leading to oil burning, increased smoking, and harmful carbon deposits.

Such situations can lead to increased emissions, decreased fuel efficiency, harmful engine deposits, and even potential engine damage.

If your engine is considerably overfilled, the safest immediate action is to drain the excess oil until you reach the manufacturer-recommended oil level. Maintaining the correct oil level and getting regular oil changes is always better to ensure good engine health.

What happens if engine oil is above Max?

If the engine oil is above the maximum level indicated on the dipstick, several negative consequences may occur, potentially damaging your vehicle’s engine.

What happens if engine oil is above Max
  1. Lubrication issues: When there is too much oil, it might get whipped into a frothy mixture due to the crankshaft dipping into it. This frothy oil does not lubricate engine components efficiently, leading to increased friction, heat, and potential engine damage.
  2. Excessive pressure: Overfilled oil can create high pressure within the engine, possibly causing oil leaks, seal damage, or blown gaskets.
  3. Increased emissions and reduced fuel efficiency: When excess oil enters the combustion chamber, it can result in increased emissions, decreased fuel efficiency, and carbon deposits on critical engine surfaces.
  4. Catalytic converter damage: Over time, excessive burning of oil can cause damage to the vehicle’s catalytic converter, leading to expensive repairs.


In conclusion, driving too much oil severely risks your engine and overall vehicle performance. Engine damage, increased emissions, and reduced fuel efficiency are just a few of the problems that may occur due to overfilled engine oil.

Maintaining the correct oil level, checking it regularly, and seeking professional help to protect your engine’s health is essential. Avoid driving your car with too much oil and act promptly to rectify the situation and ensure a longer life for your vehicle.
