Your Audi A4 sedan’s gas-powered, 201-hp 40-45 TFSI or 261-hp 45-TFSI engine requires SAE 5W-40 grade motor oil to function at its best. If SAE 5W-40 is unavailable and you need to use anything right away, you can use 5W-30 or another viscosity as long as it meets the requirements for Audi oil quality.

Which motor oil is ideal for an Audi?
Choosing the Right Oil for Your Audi Audi recommends using Castrol EDGE Professional LongLife III 5W-30 engine oil for your Audi vehicle since the two companies regularly collaborate to produce engine oils to improve performance and save fuel consumption.
What type of oil does a 3.0 liter Audi A4 require?
Parts for an oil change on an Audi A4 include 7 liters of German Ravenol motor oil, which must meet the 3.0L gasoline engines’ Audi motor oil quality standard 502 00.
Low-Shear-Rate Viscosity for 5w30 and 5w40
At 100g, the viscosity of 40 ranges from 12.5 to 16.3 mm2/s. At 100g, the operating viscosity of 30 ranges from 9.3 to 12.5 mm2/s. Both oils are 5 grade while they are cold, however at operating temperatures, 5w30 becomes 30 grade and 5w40 becomes 40 grade. With greater temperatures in the summer, 5w40 has a higher viscosity than 5w30, which aids in the motor’s continual operation.
High-Shear Rate Viscosity
This value is a minimum of 3.5 at 150g for a working viscosity of 40. The value of this parameter at 150g must be at least 2.9 for a working viscosity of 30. This indicator largely reveals how much the oil can withstand under harsh loads.
Application
Although it may be utilized by various types of cars and in a variety of temperatures, 5w30 is best in colder climates. Higher mileage engines frequently employ 5w40, which operates better in warmer climates.
Can 5W-30 be used in place of 5W40?
Using 5w30 oil:
For 5w40 oil:
This essentially indicates that each oil is equally viscous at lower temperatures and will remain so at a temperature of 30C, but that 5w40 oil operates better at higher temperatures than 5w30 oil, being effective up to ambient temperatures of 50C as opposed to 30C.
In comparison to, say, 10w40 oils, 5w40 and 5w30 motor oils have winter viscosity grades of five, making them effective down to temperatures of -30C and more viscous at extremely low temperatures.
As a result, 5w40 oils are probably utilized in higher-performance engines that operate at higher temperatures and loads than usual, such as those used in vehicles driven in metropolitan environments, which frequently sit in traffic, or in vehicles traveling at very high speeds, for example.
5w30 oils are a fantastic option if your vehicle is not made to be driven at a high rate of speed or if you drive more cautiously and sustainably. These typically perform better for certain engine parts like oil pumps, can clean the engine better, and have longer lives because they operate at lower temperatures.
How much oil is required for an Audi A4?
All TEMPS….5W-40, 5W-30, 0W-40, 0W-30 – Use a viscosity grade appropriate for the climate, season, and driving conditions where the vehicle is used if synthetic oil that satisfies the applicable Audi, Volkswagen oil quality standard with the recommended viscosity grade is not readily available in your area. Verify that the oil satisfies the requirements for Audi and Volkswagen.
