Japanese engine oils typically recommend different viscosity grades based on the climate to ensure optimal engine performance and protection. In colder climates, oils with lower viscosity, such as 0W-20 or 5W-30, are favored because they flow more easily at low temperatures, improving cold starts and reducing wear. Conversely, in warmer climates, slightly higher viscosity oils like 10W-30 or 15W-40 are recommended to maintain adequate lubrication and protect engine components under higher operating temperatures. Manufacturers like Toyota and Honda often specify these grades in their owner’s manuals, reflecting regional climate conditions. Using the correct viscosity grade helps maintain fuel efficiency, reduce engine wear, and extend engine life. Always consult the vehicle’s manual to select the most appropriate oil grade for your specific climate and driving conditions.
