What is the best oil model for Suzuki Alto?

[DelTanner]

Suzuki Alto uses 5W-20 or 0W-20 viscosity engine oil. Introduction to oil models: The oil grade indicates its viscosity specification. For example, in "15W-40, 5W-40," "W" stands for Winter. The smaller the number before W, the better the oil's low-temperature fluidity, indicating it can be used in lower environmental temperatures and provides better engine protection during cold starts. The number after W represents the oil's kinematic viscosity at 100°C, with higher numbers indicating higher viscosity. 40 means the kinematic viscosity standard at 100 degrees Celsius is between 12.5mm2/s and 16.3mm2/s. Precautions for changing oil: For new cars under normal driving conditions, if synthetic oil is used, the oil can generally be changed every 10,000 kilometers, and some can even go up to 20,000 kilometers. Under "severe driving" conditions, engine wear is greater, and the requirements for oil are higher. Therefore, it is recommended to shorten the oil change interval to effectively protect the engine.
