Carter excavators need to be operated precisely according to their specific model and engine specifications when adding oil. Generally speaking, the oil capacity of a Carter excavator will be clearly indicated in the owner's manual, but the approximate range may be between 15-25 gallons (about 57-95 liters). To ensure excellent excavator performance and extend its lifespan, it is important to use the high-quality oil recommended by the original manufacturer. In the process of changing or replenishing the oil of your Carter excavator, remember not to overdo or underdo it. Excessive dosing can lead to excessive pressure and compromise tightness, while insufficient oil can exacerbate wear and tear between engine components and reduce lubrication. Therefore, regularly checking and accurately adding the oil that meets the needs of the Carter excavator is a key part of the maintenance work. At the same time, it is important to note that before filling the Carter excavator with oil, please thoroughly drain the old oil and clean the oil pan to ensure that the new oil can fully function in a clean, impurity-free environment. To sum up, regarding the addition of oil to Carter excavators, accurately grasping the amount of oil, selecting the right specifications and quality of oil, and following the standardized operation process are the key points of knowledge that every excavator user and maintenance personnel should be proficient in. Users are reminded that before the actual operation, please be sure to refer to the official guidance instructions corresponding to your equipment model to determine the specific amount of engine oil added.
