Should Japanese cars use 0W20 or 5W30 engine oil?

[DiLevi]

Most Japanese cars use 0W20 engine oil. However, there is no single, standard, or consistent answer to this question. The type of engine oil to use is not inherently related to the country of origin of the vehicle but depends on factors such as the region, driving habits, and the specific model. To determine which grade of oil to use, it is recommended to refer to the vehicle's user manual and follow the instructions provided. Japanese cars generally refer to vehicles produced in Japan or Japanese-branded cars manufactured in other regions. Japanese cars have gained a significant market share globally due to their high cost-performance ratio, fuel efficiency, and excellent craftsmanship. The main brands of Japanese cars include: Toyota TOYOTA, Nissan NISSAN, Honda HONDA, Subaru SUBARU, Mazda MAZDA, Mitsubishi MITSUBISHI, Isuzu ISUZU, Suzuki SUZUKI, and Daihatsu DAIHATSU.
