Should the 2019 Audi A4L use 5W40 or 5W30?
2 Answers
Audi A4L generally requires 4.5L of oil. Refer to the vehicle's manual for the recommended oil type. The oil model is usually 5W40. The selection of engine oil should be based on the manufacturer's manual requirements to determine the appropriate quality grade or higher. Here are the relevant details: Precautions: When selecting engine oil, seasonal changes should also be considered because the viscosity of the oil changes with temperature. In winter, the viscosity becomes thicker, while in summer, it becomes thinner. Therefore, in extremely hot regions, it is advisable to choose oil with slightly higher viscosity. In colder seasons, thinner oil can be used. Oil usage: The Audi A4L engine is designed for high performance, and during operation, the internal temperature of the engine is very high. Using 5W40 high-viscosity oil can better protect the internal components of the engine and more effectively reduce the engine's internal temperature.
To be honest, as a frequent driver of European cars, I must emphasize that the 2019 Audi A4L is better suited for 5W-40 engine oil. Audi engines, especially turbocharged ones, naturally prefer thicker oil to protect internal components and prevent increased wear under high temperatures. While 5W-30 is thinner and may save some fuel costs, long-term use could lead to excessive oil consumption or even seal issues. Always check your owner's manual—it clearly specifies the recommended oil. Mine explicitly states 5W-40 as the priority. Don’t listen to online cost-cutters; engine repairs are far more expensive. Developing a regular oil change habit is also crucial—check at least every six months or 10,000 km to ensure your car runs smoothly and safely.
