Why Is Your Audi Is Burning Oil? (Causes And Fixes) - Car, Truck And Vehicle How To Guides - Vehicle Freak (2023)

Performing regular oil checks is a responsible and smart thing to do. Between two oil services, the engine should consume little to no oil, unless the oil consumption is specified by the manufacturer. So, let’s figure out why your Audi is burning oil and how to address the problem.

The main causes of Audi burning oil are worn piston rings, which act as a seal between the combustion chamber and the oil-drenched crankshaft. If on the other hand, the oil is lost through a leak, then it’s most likely due to a bad sump seal or oil filter. The solution is generally expensive and complicated, as it involves opening the engine and swapping out the seals.

Act promptly and have an experienced technician inspect your vehicle to avoid further damage to your engine!

4. Diminished Performance

If your Audi is suddenly performing more sluggishly, having a reduced acceleration rate, or lacking in power compared to before, it could be an indication that oil burning has caused carbon deposits to accumulate and interfere with the engine’s functioning.

5. Quicker Oil Consumption

If your Audi produces excessive oil, you will likely observe that you have to replenish the engine’s lubricant more regularly than usual. Be sure to inspect the car’s oil measurements consistently carefully – if it appears lower than expected, this could be a warning sign that there is burning taking place within your vehicle.

How to Measure Oil?

Measuring your oil is an important part of maintaining your Audi’s engine. Your vehicle’s oil level should be checked regularly to ensure that it’s at the correct level, which helps keep your engine lubricated and running smoothly.

1. Check Your Owner’s Manual

The first step in measuring your Audi’s oil is to consult your owner’s manual. The manual will provide specific instructions on how to check the oil level for your particular vehicle. It’s important to follow these instructions to ensure that you get an accurate reading.

2. Park on a Level Surface

Before measuring your oil, park your Audi on a level surface. This ensures the oil is evenly distributed throughout the engine, providing an accurate reading.

3. Let the Engine Cool Down

It’s best to check your oil level when the engine is cool. This allows the oil to settle in the oil pan, giving you a more accurate reading. Wait at least 10 minutes after turning off your engine before measuring your oil.

4. Locate the Dipstick

The dipstick is a long, thin metal rod that’s located near the engine. It usually has a yellow or orange handle that’s easy to identify. Pull the dipstick out of the engine and wipe it clean with a rag or paper towel.

5. Reinsert the Dipstick

After wiping the dipstick clean, reinsert it into the engine and make sure it’s fully seated in the dipstick tube. Then, pull the dipstick out again and look at the oil level.

6. Check the Oil Level

The dipstick has two marks on it that indicate the minimum and maximum oil levels. The oil level should be between these two marks. If the oil level is below the minimum mark, you’ll need to add oil.

7. Add Oil if Necessary

If your oil level is low, you’ll need to add oil to your engine. To do this, remove the oil filler cap and pour in the recommended type of oil in small increments, checking the oil level with the dipstick after each addition. Be careful not to overfill the engine, as this can cause problems.

In addition to measuring your oil level regularly, there are other steps you can take to maintain your engine and keep it running smoothly. Here are some tips to help you keep your engine healthy:

  • Change your oil regularly. Follow the recommended oil change interval in your owner’s manual to ensure that your engine is properly lubricated.
  • Use high-quality oil. Always use the recommended type of oil for your Audi, and choose a high-quality brand to ensure that your engine gets the best protection.
  • Check your oil filter. Your oil filter should be changed every time you change your oil. A clogged filter can cause oil to bypass it, leading to engine damage.
  • Keep your engine clean. Dirt and debris can build up on your engine, which can cause it to overheat and damage components. Regularly clean your engine to keep it running smoothly.

How Does Engine Lubrication Work?

Engine lubrication is crucial to keeping your Audi’s engine running smoothly. Without proper lubrication, the moving parts in your engine would rub against each other, causing friction and heat that could damage the engine.

The lubrication system is made up of several components that work together to provide the engine with the necessary lubrication. These components include:

1. Oil Pan

The oil pan is located at the bottom of the engine and serves as a reservoir for the engine oil. It’s designed to hold a certain amount of oil pumped through the engine to provide lubrication.

2. Oil Pump

The oil pump is responsible for circulating the oil throughout the engine. It’s typically driven by a belt or chain that’s connected to the engine’s crankshaft. As the crankshaft rotates, it turns the oil pump, which draws oil from the oil pan and sends it through the engine.

3. Oil Filter

The oil filter is designed to remove impurities from the oil before it circulates through the engine. It’s typically located near the oil pump and is replaced every time the oil is changed.

4. Oil Cooler

The oil cooler is an optional component that’s used in some engines to help regulate the temperature of the engine oil. It’s usually located near the radiator and works by circulating the oil through a series of tubes that are cooled by the air passing over the radiator.

Types of Lubricants

There are two main types of lubricants used in engines: mineral oil and synthetic oil.

Mineral Oil

Mineral oil is a petroleum-based lubricant that’s been used in engines for over a century. It’s made from crude oil that’s been refined to remove impurities, and it’s still widely used in many engines today.

Synthetic Oil

Synthetic oil is a man-made lubricant that’s designed to provide better performance and protection than mineral oil. It’s made by chemically synthesizing a variety of compounds to create a lubricant that’s specifically formulated for use in engines.

What Does the Oil Do?

The purpose of engine lubrication is to reduce friction between the moving parts in the engine, which helps to prevent wear and tear and reduces the heat generated by friction. The oil is circulated through the engine by the oil pump, which sends it to the various components that need lubrication.

As the oil circulates through the engine, it forms a thin film on the surfaces of the moving parts. This film helps to reduce friction between the parts, which prevents wear and tear and reduces the heat generated by friction.

The oil also helps to carry away heat generated by the engine, which helps to regulate the temperature of the engine. This is particularly important in high-performance engines, which generate a lot of heat.


Proper engine lubrication is also essential in preventing burning oil and maintaining the health of your engine. The lubrication system, composed of various components such as the oil pan, oil pump, oil filter, and oil cooler, works together to provide the necessary lubrication to prevent friction between moving parts in the engine. Regularly measuring your Audi’s oil level and following the recommended oil change interval can also help prevent burning oil and other engine problems.

In summary, being aware of the signs of burning oil, understanding how engine lubrication works, and taking proper care of your Audi can help keep it running smoothly for years to come. Regular maintenance, timely repairs, and using high-quality oil are just some of the steps you can take to ensure the longevity of your Audi engine. If you suspect any issues with your vehicle, don’t hesitate to bring it to a trusted professional technician to diagnose and address the problem promptly.
