Audi A4 Engine Oil Buyer’s Guide and FAQs

1. What should I do with the oil change? Especially in extreme driving conditions?

With the passage of time, the deposition of sludge increases, and the efficiency of the engine decreases. Therefore, it is needed to change the oil every 3000 to 4000 miles in normal circumstances.

If you are using the motor oil as recommended by the manufacturer, then you should change the oil every 10,000 miles or once a year. Using premium fuels can increase the intervals of oil change for your Audi A4.

Extreme driving conditions include frequent braking, shifting of gear at sustained high speed, or extreme cold or hot weather. These conditions affect the engine badly, and to cope with such conditions, an oil change is recommended every 4000 to 5000 miles.

2. What is the best-recommended viscosity of the motor oil for my Audi A4?

The viscosity is shown by two numbers. The first number with a “w” stands for winter. It shows the resistance of oil to thicken during winter, and the second number showing the resistivity of oil for thinning at high temperatures.

A 5W-20 means that the oil is fluent at 5F, and resistance in thinning is observed at 20F. The best recommended viscosity of motor oil for Audi A4 is 5W-20 or 5W-30 for the overall best performance of the engine.

3. How can I read and understand the label of the motor oil?

Before purchasing any motor oil, it is highly essential to read and understand the label. The label speaks a lot about the quality and certifications of the oil, which you should know before making any purchase. An ILSAC GF-5 or API label indicates whether the oil meets SL service ratings or not.

The starburst symbol indicates that the oil has passed all the tests conducted for the SL service standard.
The SAE viscosity label will tell you about the viscosity of the oil like 5W-20. Before buying an oil, make sure that the viscosity of the oil matches the recommended viscosity of your vehicle.

4. Why should I go for high mileage motor oil?

Many people focus on buying second-hand cars these days. Modern cars are well equipped with many features, so purchasing second-hand cars is not a bad option if you are running out of budget or you need some time in driving practice. You should go for high mileage motor oils, especially when you have a second-hand car. Having 100,000 miles on the odometer, high mileage motor oils are a good choice for second-hand cars.

5. What should I do if my Audi is burning oil? Is it normal?

Burning oil is a normal phenomenon as long as the engine is working, it will consume the oil, and the car will burn the oil. Usually, an Audi burns a quart of oil every 600 to 700 miles.

But you really need to inspect your car by yourself or by any professional mechanic if the oil burning is more than normal, and this burning of oil should be immediately fixed to prevent any loss.
