What Vehicles Are Suitable for 5W40 Full Synthetic Oil?

[LunaMarie]

5W40 full synthetic oil is suitable for the following vehicles: 1. German cars: German cars usually have turbocharged engines with larger gaps, so 5W40 (higher viscosity) oil is required. European cars also typically use 40-viscosity oil. 2. Vehicles over 7 years old: The engine may have aged and experienced significant wear. To better protect the engine, higher-viscosity 5W40 oil is needed. 3. Cars frequently driven on highways: The engine generates more heat and experiences severe wear. The meaning of 5W40 oil is as follows: 1. The number 5 before the letter W: Represents low-temperature fluidity. The smaller the number, the better the oil's low-temperature fluidity. 2. The number 40 after the letter W: Represents high-temperature viscosity. The larger the number, the better the oil's high-temperature viscosity.
