What is the appropriate amount of engine oil?

Car engine oil levels are generally normal when they are between the upper limit (MAX) and lower limit (MIN). Relevant information is as follows: 1. Function: "Engine oil" is an essential lubricant to ensure the normal operation of the engine. Its specific functions include lubricating metal parts, reducing friction between components, dissipating the immense heat generated during engine operation, cleaning fine metal debris produced by wear, as well as providing sealing, shock absorption, and rust prevention. 2. Note: When adding engine oil, be careful not to add too much or too little. The oil level should be between the "low" and "full" marks on the dipstick. An oil level that is too low can result in insufficient oil pressure. An oil level that is too full will increase the working resistance of the crankshaft connecting rod and accelerate the formation of carbon deposits in the combustion chamber.
I think engine oil level is something that requires sharing some practical experience. I used to make the mistake of checking it when the engine was hot, resulting in inaccurate dipstick readings. Now I know better – the key is to check when the engine is cold, like waiting a few minutes after turning off the engine, then pulling out the dipstick, wiping it clean, reinserting it, and checking again. The oil level should ideally be between the Min and Max marks – neither too low nor too high. If it's too low, the engine lacks sufficient lubrication, leading to increased component wear and even potential cylinder scoring. If it's too high, the oil can foam, causing unstable pressure and possible leaks. My personal habit is to check it monthly, especially before long trips – it only takes a minute or two. Another piece of advice: when getting an oil change, don't believe the mechanic if they say adding extra is better. Just strictly follow the manual's specified amount to avoid future issues.
Checking the oil level is quite simple: just ensure the dipstick reading is between the Min and Max marks, with the ideal level being at the midpoint. Overfilling oil has several drawbacks, such as increased oil pressure leading to higher fuel consumption or damage to seals. Conversely, insufficient oil can result in engine overheating or even complete failure in the worst-case scenario. I often help friends check their cars by following these steps: let the car sit for about ten minutes to cool down, then pull out the dipstick, wipe it clean, and reinsert it to measure. If the level is low, gradually add the same type of oil, avoiding pouring too much at once. Regular maintenance is crucial—I check every two weeks, especially when driving frequently. This practice saves money, ensures safety, and extends engine life.
