Whether it is heavy-duty equipment or road vehicles, the engine is full of moving parts, and these moving parts rely on sufficient engine oil to operate normally. Most equipment also consumes a small amount of oil during operation. Lack of engine oil can lead to catastrophic engine failure; therefore, regular inspection of oil consumption is very important. Otherwise, it may result in expensive repair costs. The good news is, prevention is very simple. By learning how to correctly check the oil, read the engine oil dipstick, and refill on time, most serious problems can be avoided. This guide will lead you through each step, ensuring you grasp the necessary knowledge and keep your equipment running strongly.
