The oil change in the Audi A6 C6 is done once a year or after every 15,000 km. It is worth noting that the Audi A6 C6 series is represented by many models with different volume and modifications of engines, which affects the replacement of oil in them.
We will consider the example of an Audi A6 C6 with a 2.0 diesel engine.
Engine oil must meet the specifications in the Audi service book.
For gasoline engines, the oil specification VW 50101, VW 50200, VW 50400, VW 50501 is established. diesel engines VW 50700 oil is used. Only as an exception, VW 50600/VW 50601 or VW 50500/VW 50501 oils can be used.
Mixing of oil with other types of oils is not allowed.
In some cases, when the oil level drops to a critical level, you can add another oil (but not more than 0.5 liters) of the corresponding specifications VW 50600 / VW 50601 or VW 50500 / VW 50501.
A6 owners prefer to fill in such oil:
- Mobil1 5W30;
- Total Quartz Ineo Long Life 5W30;
- Motul 8100 X-Cess 5W40;
- Castrol Edge 5W30.
The viscosity of the oil may vary slightly depending on operating conditions and climatic conditions.
It should be noted that depending on the driving style and operating conditions, oil consumption can be up to 0.5 liters. per 1000 km. For the first 5,000 km, oil consumption may exceed this value. Recommended for every long trip check engine oil level.
If the oil level falls below the permissible value, the oil level symbol "Bitte Ölstand prüfen" will light up (please check the oil level). When the oil level indicator light comes on, add oil.
When measuring the oil level, the vehicle must be on a flat horizontal surface. After turning off the engine, it is necessary to allow time for the oil to glass into the sump.
The oil level must never exceed the upper limit mark on the dipstick. If this happens, the oil will be released into the atmosphere through the crankcase ventilation and exhaust system. Also, the oil will burn in the catalyst, which can cause damage to it.
How many liters of oil to pour?
- Engine 2.0 TFSI - 4.0L;
- Engine 2.4 MPI - 6.4L;
- Engine 2.7 - 7L;
- Engine 2.8 FSI - 6.3L;
- Engine 3.0 TFSI - 6.6L;
- Engine 3.0 TDI - 6.4L;
- Engine 3.2 FSI - 6.6L;
- Engine 4.2 - 7.5L;
When changing or topping up oil, do not allow oil to get into hot engine- risk of fire.
To work on changing the oil you will need: 32mm wrench (socket for cup oil filter), 19mm wrench for the drain bolt, screwdriver, new oil filter, new seal ring on the oil filter box, container for draining used oil.
After warming up the engine (15-20 minutes), we find the oil filter cover.
Using a wrench and a 32 mm socket for the oil filter cup, unscrew the oil filter.
The oil drain plug is located in an accessible place on the bottom of the engine just behind the car's bumper.
We unscrew the bolt to drain the oil from the engine, after placing the container into which the old oil will flow.
We are waiting for the oil to drain from the engine.
In order to avoid "annoying situations", we twist the cork back!
We return to our filter. We take a paper towel or a rag and just take it out of the nest. Extreme caution! We do not allow oil to get on the engine, because. the engine is still hot and may cause a fire.
Separate the filter cover from the filter itself.
in engine oils Castrol long life for AUDI A6 (C7) used a special set of additives. Thanks to him, the manufacturer promises to preserve all the properties of his premium (EDGE) product throughout the entire period until the next MOT. In some European countries, when filling this oil, it is allowed to increase the service interval.
What should this oil do? Firstly, this is a reduction in engine noise, secondly, better lubricating properties, and thirdly, a reduction in fuel consumption. In fact, all manufacturers add such additives, but only the largest of them can afford to test on real samples and assemble the best kit.
That is why these brands are presented in our auto parts store. Buying them, you can be sure of the reliability and correctness of the choice.
Buy original oil Audi 5W30
Lubrication reduces friction between the mating surfaces of engine parts (cylinders, piston, camshaft). In addition, the working fluid contributes to fuel efficiency and increase the efficiency of the engine. To extend the life of the power unit, you need buy original oil Audi 5W30 and replace it regularly. Part numbers branded products - G055195M4 and G055195M2.
Lubricant change
The fact is that there are lubricating components in the technical fluid that accumulate sediments, as well as combustion and friction products. Thus, the lubricant naturally becomes contaminated during the operation of the machine. Even the most expensive and quality product loses its original characteristics over time and needs to be replaced.
You need to update the fluid regularly. Pour fresh branded oil it is necessary at intervals prescribed in the vehicle instructions 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 Volkswagen AG engineers, has the abbreviation VW 5 (XX.XX). Products comply with a certain class of standardized systems of the Association of Engineers of the American automotive industry and the Association of European Automobile Manufacturers.
VW 504.00 engine oils are by far the most popular among specifications for Vehicle with petrol engines. 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 VW 503.00 and VW 503.01 standards for gasoline engines. Therefore, cars of older years of manufacture can use products of the new series of approval. All products have one viscosity grade 5W30.
Specification VW 507.00 is new standard VAG, which is designed for diesel modifications with or without particulate filter. It contains a minimum of sulfate ash, phosphorus and sulfur, therefore, the service life of the filter element is significantly extended.
Without lubricants, the friction forces arising between the rubbing elements of the motor would be much greater, the parts would heat up faster, as a result of which the power unit would jam. The use of lubricant contributes to the formation of a protective film on the internal elements of the engine, protects it from premature wear. We suggest that you familiarize yourself with the parameters of the recommended engine oil for the Audi A6.

The manufacturer pours into new cars motor lubricant which can be used throughout the year. For most Audi A6 models, it is recommended to pour synthetic lubricants, as they have a larger operating temperature range than semi-synthetics and mineral water. It is forbidden to use additional additives to engine oil.
The German brand Audi dates back to 1910. August Horch became the founder of the company, due to some legal subtleties, the owner could not use his last name to name the concern, and he called it Audi, this word in Latin means “I hear”. famous logo, which features four rings, appeared in 1932. In 1965, Audi was bought Volkswagen Group, since then for more than half a century this brand has been owned by the VAG group.
Audi Model A6 has been in production for over 20 years. This german car replaced the popular Audi 100 at the end of the 20th century.

The Audi A6 C5 is a premium luxury car produced in sedan and station wagon bodies from 1997 to 2004. It is positioned as the second generation of the A6, whose history began in 1994 (instead of the Audi 100). The car could be purchased with petrol power plants 1.8-3.0 l (125-250 hp), including those with turbocharging. They also offered diesel versions with a volume of 1.9 and 2.5 liters. The "charged" modifications of the S6 and RS6 had 335 and 444 hp engines under the hood. With. respectively. In 1999, the front-wheel drive A6 was first equipped with a CVT. Even by that time, an off-road version of the A6 appeared in the station wagon body (with the Quattro prefix). In 2001, the design and body of the car were restyled. The suspension and engine range has also been upgraded. In 2004, the next generation C6 replaced the Audi A6 C5.
Regulations for changing the oil in the internal combustion engine
Experienced motorists and experts recommend changing the oil in the Audi A6 C5 engine every 10-15 thousand km. If there is old oil in the engine, as well as a systematic refusal to replace it, you will have to face serious consequences. Let's consider some of them:
- The oil becomes obsolete, and its lubricating and protective properties become unusable, which leads to an increase in the effect of dry friction of moving parts that interact with each other. As a result, the load on the engine increases, which in worst case may knock. It will lead to the inevitability overhaul. The engine resource is reduced to the limit, because of which it will be necessary to raise the issue of replacing the engine or selling the car for spare parts. In less advanced cases, the owner will face increased consumption fuel and internal combustion engine overheating
- Outdated used oil removes heat much worse, engine parts overheat, heat up and melt
- Reduced corrosion protection
- Wear products and other dirt deposits accumulate in the engine, they become more and more in the oil channels, which become clogged, which leads to the inevitability of a major overhaul.
What kind of oil to fill in the Audi A6 C5 engine
- Original - 5W-30, 5W-40
- Alternative - Mobil 1 5W-30, Total Quartz Ineo Long Life 5W-30, Motul 8100 X-Cess 5W-40, Castrol Edge 5W-30, Liqui Molly.
