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. Use SAE 5W-30 for diesel engines.

What kind of oil is best for an Audi A4?
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.
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.
Which oil is ideal for TDI engines?
You can’t go wrong with synthetic oil if you’re seeking for the best oil for your diesel engine. Due to its ability to tolerate high temperatures and harsh conditions, synthetic oil is perfect for use in diesel engines. Additionally, it offers better defense against deterioration, assisting in extending the lifespan of your engine.
There are a few considerations to make while selecting the best synthetic oil for your diesel engine. First, think about the oil’s weight. While lesser lubricants might provide better fuel economy, heavier oils often do a better job of preventing wear and tear.
Second, think about the environment in which you’ll be operating your engine. If you reside in a cold climate, you should choose an oil that won’t thicken in the cold and cause engine issues. On the other hand, if you reside in a hot environment, you’ll need an oil that won’t degrade and result in engine issues while it’s hot.
There is a synthetic oil out there that is ideal for your diesel engine, no matter what your needs are. Finding the best oil for your needs is simple with the wide variety of alternatives available. So stop waiting and switch to synthetic oil right away to start reaping the rewards of better performance and longer engine life.
When selecting new engine oil that is best for your diesel, always do your study. Talk to one of our knowledgeable technicians if you have any questions; they will be pleased to assist you.
Need special oil for TDI?
There are many viscosity ratings for oils in Europe and America. Additionally, there are a few trends in the oil sector regarding viscosity:
- Numbers for oil viscosity are decreasing.
- Compared to before, lighter oils perform better at high temperatures.
The use of lower weight lubricants has frequently been mandated by manufacturers due to emissions and fuel economy standards. Lightweight oil makes a difference in how well cars perform in the EPA cold start test. Furthermore, engine tolerances are significantly tighter now than they were before. Thinner oil can help with lubrication in the crucial moments just after a cold start (particularly when it’s cold). Today’s synthetics also offer significantly better heat protection than mineral-based oils did, despite having lower viscosity ratings. In PD and Common Rail TDIs, for instance, 5W30 weight oil is regarded as suitable for all driving circumstances, even in the summertime desert.
With the greatest range of viscosity ratings among VW oils, 505.00 oils (for rotary pump TDIS) include 0W30 and 0W40. The most popular oil in this category is 5W40, but many owners in cold climates prefer to use 0W30 or 0W40 in the winter.
Additionally, oils satisfying the 505.01 standard are available in both 5W30 and 5W40 grades (PDs). While both are suitable for use in all environments, some owners prefer 5W40 to 5W30.
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 catalog. When temperatures drop, the product will deliver exceptional engine performance and live up to the brand name.
Can I substitute 10w40 for 5W-30?
5W-30 oil is not used in your car. According to Kia literature, 10W-40 oil viscosity is advised for your car. You can use 5W-30 oil if the outside temperature is considerably below 32 degrees when you are driving the car, but you can also use 10W-40 if the outside temperature is below freezing. Requesting an engine oil/filter change will have the answering mechanic take care of this for you if you prefer that this maintenance be done by a qualified Mechanic sent directly to your location by YourMechanic. Do not hesitate to get in touch with YourMechanic again if you have any more queries or worries.
What is the purpose of 5w40 oil?
In American diesel pickup trucks and European cars with gasoline engines, the 5W-40 viscosity is frequently advised for performance engines.
Consider Mobil SuperTM Synthetic Euro or Mobil 1TM Formula M if you drive a contemporary European vehicle. Below, compare these two oils. They can be applied to both diesel and gasoline engines.
Choose between Mobil 1TM Turbo Diesel Truck or Mobil Delvac 1TM ESP if your diesel engine needs an oil that complies with CK-4 requirements. Notably, we do not contrast motor lubricants designed for gasoline-powered vehicles with those for diesel engines.
Why are there different numbers in 5W-40? The figures represent the oil’s weight and thickness, or viscosity. When it’s cold, motor oil thickens; when it’s hot, it thins. The first value represents the oil’s viscosity when it is cold, while the second number represents the viscosity when it is operating temperature.
