I must say Rumesh you have given the wrong answer. Never intermix Synthatic and Mineral Oils.They do not compatible because made differently. Japan has summer temperatures above 30 Celsius. So dont go against manufacturer. Use 0w-20. Nothing higher than 20. 20 viscosity is maintain until 100 degrees. Oil temperature. Normal oik temperature if u check when engine running is less than 60 degrees. Please if you dont know dont post wrong advice.
