The oil change interval of a Carter excavator is closely related to its working environment, work intensity, and the type of oil used. In general, the recommended replacement interval for high-quality original Carter oil is approximately 500 to 1,000 hours or every 3,000 to 5,000 km. However, the exact replacement time also needs to refer to the actual operating condition of the equipment and the manufacturer's official recommendations. When it comes to maintaining your Carter excavator, it's crucial to check the condition of the oil regularly. When the oil color becomes darker, impurities increase, or viscosity decreases, even if the preset operating kilometers are not reached, the oil should be changed in advance to ensure good lubrication and cooling of the engine and prolong the service life of the excavator. In summary, a Carter excavator oil change does not depend solely on the number of kilometers driven, but also on a variety of factors. As an owner or operator, you need to pay close attention to the guidance in the equipment maintenance manual and change the oil in a timely manner according to the actual use. Here, we especially remind that following the manufacturer's guidelines and reasonably planning the excavator oil replacement plan is one of the key links to ensure the efficient and stable work of the Carter excavator.
