4.4 Fuel, coolant and lubricants Proper selection of fuel, coolant and lubricants Maintenance REMARK When fuel sulphur content is less than 0.5%, change oil in the oil pan according to the periodic maintenance hours described in this manual. Change oil according to the following table if fuel sulphur content is above 0.5%. When starting the engine with an atmospheric temperature of lower than 0°C (32°F), be sure to use engine oil of SAE10W, SAE10W-30 and SAE15W-40, even though the atmospheric temperature goes up to 10°C (50°F) more or less during the day. Use API classification CD as engine oil and if API classifica- tion CC, reduce the engine oil change interval to half.
There is no problem if single grade oil is mixed with multi- grade oil (SAE10W-30, 15W-40), but be sure to add single grade oil that matches the temperature range in the table. We recommend KOMATSU genuine oil which has been spe- cifically formulated and approved for use in engine and hydraulic work equipment applications. Specified capacity: Total amount of oil including oil for com- ponents and oil in piping. Refill capacity: Amount of oil needed to refill system during normal inspection and maintenance.
