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.

In an Audi A4, may I use 5W-30?
For normal driving situations, you can use oil with a viscosity of SAE 5W-40 for gasoline engines in all temperature ranges. If the viscosity grade is not readily accessible, you can use 5W-30 or another grade as long as it satisfies the appropriate Audi oil-quality requirement.
Which oil does Audi suggest?
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 occurs if I use 5W-40 as opposed to 5W-30?
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.
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 parameter 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.
Does Audi require particular oil?
Volkswagen’s subsidiary Audi makes high-end automobiles. This German firm is well-known for its luxury automobile models. To ensure that their top-of-the-line automobiles and SUVs work at their best, they advise using premium engine oils. The top five motor oils for an Audi are listed below.
Castrol EDGE Professional 5W-30
Audi specialists and many other premium automobile manufacturers favor Castrol synthetic motor oil. Castrol engineers collaborate closely with luxury automakers to develop special oil compositions that optimize engine performance. The majority of Castrol synthetic oils are certified by Audi and won’t void your warranty.
Castrol EDGE Professional 5W-40
Here is another another top-notch Castrol oil recipe that is suggested for Audis. All of the high-end Castrol synthetic motor oil mixtures are excellent choices. The viscosity is the primary distinction between this blend and the 5W-30 blend. This mixture works better at high temperatures and is more aggressive.
Mobil 1 Synthetic Oil
Here is an additional motor oil that Audi has approved. To meet the needs of any vehicle, Mobil offers a wide variety of oil compositions. This synthetic mixture will improve the performance of your Audi engine.
Pennzoil Platinum Euro Oil
Another reliable oil brand for your Audi is Pennzoil. The special qualities of the Platinum formula increase engine life. As opposed to many other oil brands, this one’s base oil is created from natural gas, which has less characteristics that can clog engines.
Pentosin High Performance II
Many different automotive fluids are produced by Pentosin. Another choice for your Audi is their high-performance motor oil blend. Pentosin is a brand that you won’t find in every petrol station or grocery shop, but you can count on finding it in every authorized Audi garage.
Can normal oil be used in an Audi?
You might not be aware of this odd restriction about regular and synthetic oil in your engine if you’ve never owned a German vehicle. There are a number of reasons why you shouldn’t use normal oil in an Audi or BMW, but perhaps the most significant is that doing so will void the vehicle’s warranty.
Can I use 0w40 for 5w40?
The cost of 0w40 and 5w40 is another aspect to consider. The brand determines the price, which does not vary significantly. For instance, if you choose the Pennzoil Ultra variant, you see that the price difference between 0w40 and 5w40 is one dollar.
Despite the fact that Castrol engine oil comes in a variety of forms, certain brands like them have a higher variation. To get the proper oil bottle, you must be precise.
Q: Can I Use 0w40 Instead Of 5w40?
Given that some industry insiders advise against it, many individuals are worried about substituting engine oils. Since 5w40 and 0w40 have so many qualities in common, you can utilize them interchangeably. You can switch to the 0w40 for icy circumstances because it has exceptional mobility in a frigid climate.
Q: What Is 0w40 Oil Used For?
Ow40 oil is perfect for cold weather because it has no viscosity when the temperature drops. When it’s heated, the multi-grade oil has an operating thickness of 40. Since it will protect engine parts while they are hot and flow easily when they are cold, 0w40 is quite adaptable.
Q: Is 0w Better Than 5w?
The W stands for winter in the majority of oil-grade alphanumeric systems. The 0w will perform better than the 5w in the winter when driving conditions are poor due to the cold because it is less thick. The oil’s thinness makes it useful for lowering friction and facilitating the movement of engine parts.
Q: Is 0w40 Good For Winter?
0w40 is a multi-grade oil that performs well in both mild summer heat and winter weather. Wintertime air density is shown by the number 0, which is the perfect amount for effortless passage. The lubricant’s performance is impacted if it thickens owing to freezing temperatures.
Q: Is 0w40 Good For Summer?
When you consider 0w40’s features, it has a lot of flexibility. It functions in mild summers and winters. When heated, it will achieve a viscosity level of 40, as suggested by its name.
Q: Is Mobil 1 0w40 good oil?
One of the most well-known lubricant producers, Mobil 1, has locations all over the world. The 0w40 lubricant is available through Mobil 1’s extensive portfolio. When temperatures drop, the product will deliver exceptional engine performance and live up to the brand name.
