How to Check if the Engine Oil is Sufficient?

[StJustin]

Automobiles are usually equipped with an oil dipstick to check the oil storage level. The dipstick has clear upper and lower limits marked as H and L, where H represents the highest oil level (upper limit) and L represents the lowest oil level (lower limit). When the oil level falls below the L mark, the vehicle's oil warning light will illuminate, alerting the owner that the engine oil is insufficient and needs to be replenished promptly. More information about automotive engine oil is as follows: 1. As long as the oil level is between the upper and lower marks or at the 3/4 position, the vehicle's oil level is still sufficient for normal operation. 2. When checking the oil, the vehicle must be parked and turned off, placed on a level surface, and the oil should be checked three to five minutes after turning off the engine to ensure accuracy.
