The Caterpillar excavator is a highly acclaimed heavy machinery equipment, distinguished for its outstanding performance and durability among numerous brands. Regarding the fuel usage of the Caterpillar excavator, especially the selection of oil grade, has always been a focal point of concern for many users. Generally, Caterpillar excavators are recommended to use diesel fuel, and the specific type of diesel fuel needs to be determined based on the specific model of the equipment and the official recommendations of the manufacturer. When selecting diesel fuel, it is necessary to ensure that it meets the National VI standards and matches the compression ratio and performance of the excavator engine, so as to fully exert the power efficiency of the Caterpillar excavator and minimize potential damage to the machine. As for the oil part, for example, certain models of Caterpillar excavators may require the use of 15W-40 APICI-4 grade diesel engine oil, but this is not the standard configuration for all Caterpillar excavators, so it is essential to refer to the operation manual or consult the dealer to accurately understand the grade of oil that should be added. In summary, regarding the question of 'what grade of oil should be added to the Caterpillar excavator,' there is no uniform answer, the key is to follow the manufacturer's guidance, ensuring that the selected oil can meet the equipment's operational requirements and effectively protect the excavator engine, prolonging its service life.
