20. USE FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE REMARK We recommend Komatsu genuine oil which has been specifically formulated and approved for use in engine and hydraulic work equipment applications. Only use high quality oils wich meet internationally recognised specifications. When starting the engine in an atmospheric temperature of lower than 0 o C, be sure to use engine oil of SAE10W, SAE10W-30 and SAE15W-40, even though an atmospheric temperature goes up to 10 o C more or less in the day time. Use API classification CE or CF-4 as engine oil. If API classification CD is used reduce the engine oil change interval to half.
There is no problem if single grade oil is mixed with multigrade oil (SAE1OW-30, 15W-40), but be sure to add single grade oil that matches the temperature in the table. When fuel sulphur content is less than 0.5%, change oil in the oil pan every periodic maintenance hours described in this manual. Change oil according to the following table if fuel sulphur content is above 0.5%. Specified capacity: Total amount of oil including oil for components and oil in piping. Refill capacity: Amount of oil needed to refill system during normal inspection and maintenance.
