Audi A4 oil Types

With newer models of the Audi A4, the engine configuration has gradually changed along with the car. I’m sure you are aware of it. And with changing configuration, the oil requirements for each model might’ve changed too.

You don’t want to use the wrong oil in your precious car, so what you got to know before anything else is, the compatible oil type for your Audi A4.

The oil consumption rate for Audi A4

Some of my fellow mates who just started using their new Audi A4 faced a common issue of burning oil in their Audi. Now, to solve this problem, What you should do is get to the root of it. Hence, first, you need to know the actual oil consumption of your car. Once you observe the frequency of oil changing in a certain period, it’ll be clear to you.

According to Audi, you won’t need to change the car oil before it reaches a 6000 miles stop. However, when asked to users, they saw the necessity of changing it after 4000 miles or less. The first interval works as your engines break-in period. After this period, you’d probably need to lower the oil changing interval as your vehicles ages. So, why is it necessary to know this rate? Knowing the actual consumption rate, you can keep a check on the oil burning.

Oil changing intervals for Audi A4

Have you been struggling with frequent oil changing these days? Well, it’s familiar with aging vehicles as the engines get old too. Your old engine gathers more deposits, and the sludge build-up increases. Hence, the solution? Changing the oil and the oil filters from time to time.

So, if you have an old vehicle, you must keep a check of the oil level so that your vehicle can run smoothly without overheating. And of course, you wouldn’t like the struggle of regular oil changing. That’s why my suggestion would be to settle for motor oil that decreases the deposit formation to a great level. Do you know what that means? A clean engine with a frictionless smooth ride.

Oil Additives

With more conventional oils, there isn’t much scope to resist the effect of external elements. However, due to the advancement in motor oil manufacturing, different types of additives are added to tackle these problems. So, what kind of external elements am I indicating? Dust, dirt, ageing of engine, heat, cold, and moisture, etc. If your engine oil can’t deal with these elements, then it’s for a change.

For instance –

– Detergents to minimize residue build-up

– Improved viscosity to maintain oil flow rate at both high and low temperatures

– Antiwear and antioxidant agents to limit wear and prevent oxidation respectively

– Friction modifiers to improve fuel economy

– Corrosion inhibitors to keep check of rust and corrosion.


Viscosity is what determines your Audi A4 oil type recommendations. It indicates the resistance of a fluid’s flow. Now, you are familiar with the numbers like 5w-30 or 10w-40. The first one represents low-temperature ratings, and the second one represents high temperatures; the ‘w’ indicates winter. That means the lower coefficient of the ‘w’ means it’s ideal for using in cold temperatures.

Your car engine oil will thicken during winter or cold weather whereas it gets thinner in hot weather. Hence, you need your perfect Audi a4 oil type or configuration to make the best use of the fluid in both climate conditions. 

Now, look at the number ‘5w-30’, it means the oil will keep flowing at a normal rate at 5F and also protect from thinning at 30F. As per Audi, the recommended Audi A4 oil type is 5w-20 or 5w-30. If you want some top-notch performance from your engine, don’t compromise!

Understanding the specifications

If you don’t understand the labels on the motor oil and if it’s compatible with your car configuration, then boy! Your frustrations levels are going to reach the peaks!

Let’s start with a few terms. There will be an API or ILSAC GF-5 label which will assist you to know if the oil fulfills the SL service ratings. In case of diesel, you’ll see a C on the bottle. If you find an SAE viscosity label, then know that the oil in hand has succeeded the energy conservation test. And lastly, if there is a starburst symbol, then you are in for a deal because that means it has passed all the SL service standards tests.

If you are going to skip the label reading, it wouldn’t be a wise choice. Nevertheless, you don’t want to make any mistakes when choosing the most significant thing to run your valuable vehicles.

Extreme driving conditions

If you don’t understand what this extreme driving indicates to, let me help you with that. If your Audi A4 has to go through frequent gear shifting or braking at high speed sustained throughout the whole driving period, I’m sure you can understand the intensity of the ride. Apart from the rough driving styles, you might also need to face hotter or extremely cold weather. Even if not that, the prolonged idling may cause some severe damage to the engine, and that would fall under extreme conditions as well. Well, you’ll know it after you take out your car from the garage after a few months.

Such rough and harsh conditions may have a heavy impact on your vehicles over time. Of course, you don’t want untimely engine damage and so keeping a check of the oil levels is a must.

According to professionals, if your vehicle often falls under such maximal situations, then oil changing is recommended every 5000 miles at max.

Overheating protection

All the features of an efficient engine oil work together to protect the engine against overheating. For instance, better viscosity ensures that the oil reaches all the engine gears to keep them running smooth, hence preventing overheating. Again, dispersants don’t allow the formation of sludge and so eradicates friction, ultimately saving from overheating.

If you want your car engine to have an extended life, then you need to do everything to prevent overheating. And trust me, it isn’t that difficult, all you got to do is choose the right oil for your engine.
