An engine oil check involves examining the level and condition of oil in a vehicle’s engine. It allows you to monitor oil quantity, ensuring it is within the specified range indicated on the dipstick. For instance, if the oil level is too low, there may not be sufficient lubrication for engine components, potentially causing damage.
Regular engine oil checks are crucial as they can help prevent costly repairs. They ensure that oil is not overfilled or underfilled and that it has not become contaminated or degraded over time. Historically, the advent of the dipstick in the early 1900s revolutionized engine oil checks by providing a simple and accurate way to measure oil levels.
