Can You Drive When the Engine Oil Reaches the Lower Limit?
2 Answers
Engine oil near the lower limit does not affect the car. Only when it falls below the lower limit is it considered insufficient, and engine oil needs to be replenished promptly. Here are specific details about engine oil levels: 1. The engine oil level should be maintained between the upper and lower marks on the dipstick. Excessive oil can enter the combustion chamber through the gap between the cylinder and piston, forming carbon deposits. 2. Carbon deposits can increase the engine's compression ratio, raising the likelihood of knocking. 3. Excessive oil increases the stirring resistance of the crankshaft and connecting rods, leading to higher fuel consumption. It also raises internal engine pressure, which can cause oil leaks from engine seals.
The engine oil has reached the lower limit, and I believe this situation should be taken seriously. The engine relies entirely on oil lubrication to operate properly. Low oil level means increased friction between internal components, accelerated wear, and the risk of engine overheating or even severe damage. I once helped a friend deal with a similar issue—his car started smoking halfway, nearly leading to a total engine failure, and ended up requiring extensive repairs. If your car's oil level is now at the lower limit, I recommend stopping immediately to check. With the engine cold, pull out the dipstick to inspect the level. If it’s indeed below the minimum mark, don’t risk driving long distances. If you must drive to a nearby repair shop, maintain a slow and steady speed, avoiding sudden acceleration. The best course of action is to immediately top up with the same type of oil to the mid-level mark. Developing a habit of checking the oil level monthly can prevent such issues—for example, taking a quick look each time before refueling.
