The business class car Audi A6 appeared in 1994 as a replacement for the Audi 100 (C4). The fourth generation of the model is currently being produced. The A6 has sedan and station wagon versions, with front or permanent all-wheel drive. Depending on the model year, the model was equipped with gasoline atmospheric and turbocharged engines of various configurations (in-line 4- and 5-cylinder, V6, V8) with a volume of 1.8 - 4.2 liters or diesel TDI engines of 1.9 - 3.0 liters. The sports cars of the S6 and RS6 modifications were equipped with V8 and V10 engines with an output of up to 579 hp.
What kind of oil to fill in the Audi A6 engine depends on its modification and the age of the car.

Happy owners of Audi A6 C6 cars are sure to face the question of what needs to be poured into the engine for its normal operation? And believe me, the question is quite acute, since the opinions of car owners were divided, and few people can support their argumentation with documents, since most of the cars were imported from Germany, which means that instructions in Russian were not attached to them.
Today we will analyze this topic without leaving open questions for discussion. Naturally, for this we will use the documents. Also, using the example of a 2-liter diesel engine, let's see how do-it-yourself grease change is carried out.
Review of the documentation for the Audi A6
The whole confusion began due to the fact that for cars with Long Life Services maintenance, to which the model in question belongs, it is required to fill in engine oil with the appropriate mark. What does this mean in practice?
- The specified class of maintenance implies that the oil in the Audi engine must be changed every 2 years or 30,000 km.
- Accordingly, the oil must have such characteristics that will allow it to serve as long.
And most of the owners did just that - they needed oil, which is quite expensive. After all, on what you will not go for the sake of your beloved iron friend.
And everything would be fine if information resources on the Internet did not claim that filling with ordinary oils is impossible, but in fact everything is somewhat different.
This is what the car's service book, printed in Russian, says:
Engines of A6 C6 vehicles support two types of maintenance: Long Life and Inspection.
We have already written everything about the first mode.
The second allows the use of standard oils, which are changed every 15,000 km or 12 months.
And here is another photo, which describes the frequency of oil changes during inspection service.
Therefore, we immediately issue our verdict - the statement that it is necessary to use only "long-playing oil", we consider unreasonable.
Interesting to know! Automotive "brains" can independently calculate the time to change the Audi engine oil. The idle time, driving style and other factors affecting the deterioration of the properties of the lubricant for the motor are analyzed.
This feature is available for Long Life Services. Alternatively, you can set a mode in which the computer will signal the need for replacement after a certain mileage.
So, to summarize, we will additionally clarify the tolerances. For Long Life Services maintenance mode you can use labeled 504/507 oils.
For the inspection regime, oils VW 501 01, 502 00, 504 00, 505 01 are used. More accurate information can be obtained for a specific type of engine.
What oil to choose for Audi A6 C6
Advice! When changing the oil, in no case is it allowed to mix compounds with different characteristics.
The best option for a diesel engine would be the VW50700. If the oil level has dropped significantly, then no more than 0.5 liters of another type of composition can be topped up.
From which manufacturers is the oil in the Audi A6 best to choose? Most Audi A6 C6 owners prefer the following brands:
- Mobil 5W30;
- Castrol Edge 5W30;
- Total Quartz Ineo Long Life 5W30;
- Motul 8100 X-cess 5W40.
The viscosity of oils is also of great importance. This parameter is determined depending on the climatic conditions of use of the product.
Instructions for changing the oil in the Audi A6 C6
Now let's look at the complete procedure for changing the oil in the Audi A6 C6 engine.
We start by opening the hood and finding the oil filter cover under it.
Advice! Before starting to change the engine oil, it must be warmed up for 10-15 minutes. Warm oil will be thinner, which means it will drain more easily.
We unscrew the oil filter. We do this with a 32 mm wrench (oil filter cup socket).
Removing the oil filter
In this car, the engine oil drain plug has received an accessible location.
Unscrew the plug
It is located almost immediately behind the front bumper of the car.
We substitute the container for working off from below and unscrew the cork with a 19 key.
The oil will then flow downward. We wait until the old grease is completely drained.
As soon as the flow has stopped, we return the plug to its place.
Now you need to remove the oil filter. In order not to burn yourself and not get dirty, use a clean rag.
We take out the old filter
Advice! Be extremely careful not to drip oil onto the engine, as this could result in a fire as the engine is still hot.
We take a new filter and also lubricate the small ring at its bottom, as shown in the next photo.
Filter lubrication prior to installation
We carry out the installation of a new filter by screwing the cover into place with a key.
Pour new oil into the engine in the required amount through an ordinary funnel. For a 2 liter engine, this is 4 liters.
We check the oil level with the dipstick and let the engine idle a little.
This completes the procedure for replacing engine oil in the Audi A6 C6. As you can see, there is nothing difficult here. The manufacturer made everything as user-friendly as possible.
Useful information
At the end of the material, I would like to talk about some points that will definitely come in handy for every owner of the Audi A6, and other cars too.
A car engine can consume up to 0.5 liters of motor oil for every 1000 km, which largely depends on its technical condition and the driver's driving style.
Additionally, the "Bitte Ölstand prüfen" light will help control the oil level, which will light up on the dashboard when the oil level reaches the lower critical mark. As soon as this happens, immediately add grease.
The oil level is checked only on a flat horizontal surface, otherwise the measurements will have inaccuracies.
When adding oil, it is very important not to exceed the upper level mark. Otherwise, it will be thrown out through the crankcase ventilation system and exhaust gases. At the same time, it will burn in the catalyst, which can soon lead to its damage.
This concludes our brief overview. We have analyzed which oil for the Audi A6 C6 you can use for replacement, and also considered how to do this procedure correctly. Now you can service your car yourself as soon as you need it.
The German brand Audi traces its history back to 1910. The founder of the company was August Horch, due to some legal subtleties, the owner was unable to use his surname for the name of the concern, and he called it Audi, this word is translated from Latin as “I hear”.

Buy original oil Audi 5W30
Lubrication reduces friction between the contacting surfaces of engine parts (cylinders, piston, camshaft). In addition, the working fluid contributes to fuel efficiency and increased engine efficiency. To extend the service life of the power unit, you need buy original butter Audi 5W30 and replace it regularly. Catalog numbers of branded products - G055195M4 and G055195M2.
Changing grease
The fact is that the technical fluid contains lubricating components that accumulate sediments, as well as combustion and friction products. Thus, the grease will naturally become contaminated during machine operation. Even the most expensive and high-quality product loses its original characteristics over time and needs to be replaced.
You need to update the technical fluid regularly. Fill in fresh branded oil at intervals prescribed in the vehicle manual and developed by German specialists, taking into account the peculiarities of the engine and operating conditions. At the same time, a new filter is installed during maintenance.
Product selection
The Audi tolerance system, developed by engineers at the Volkswagen AG, is abbreviated as VW 5 (XX.XX). The products comply with a specific class of standardized systems by the American Automotive Engineers 'Association and the European Automobile Manufacturers' Association.
Engine oils VW 504.00 are by far the most popular specification for vehicles with gasoline engines. The products are recommended for cars with a standard service interval (15,000 km or 12 months) and with an extended Longlife (30,000 km or 24 months).
The approval also applies to the old standards VW 503.00 and VW 503.01 for gasoline engines. Therefore, cars of old production years can use products of a new series of approval. All products have one viscosity grade 5W30.
VW specification 507.00 is the new VAG standard, which is intended for diesel versions with or without a particulate filter. It contains a minimum of sulphated ash, phosphorus and sulfur, therefore, the service life of the filter element is significantly extended.
