Is 4 Liters of Engine Oil Enough for One Maintenance?
2 Answers
Generally, 4 liters of engine oil is sufficient for one maintenance. The exact amount of oil needed depends on the vehicle model, and some models may require different amounts of oil due to varying engine displacements. Here is relevant information: 1. Too much oil: This can easily increase engine load and affect performance; over time, the engine's exhaust ventilation system may also be damaged, carbon deposits may increase, and excessive oil may cause some oil to enter the combustion chamber, leading to oil burning. 2. Too little oil: This will result in insufficient lubrication of engine components, accelerating their wear. Oil also plays a crucial role in cooling and heat dissipation. If the oil level is too low, the engine's cooling and heat dissipation capacity will weaken, causing internal overheating and further leading to phenomena such as bearing seizure and cylinder scoring.
Having driven for over a decade, I've found that whether 4 liters of oil is enough for one maintenance depends entirely on your vehicle type. For instance, my old sedan uses exactly 4 liters per oil change, while my friend's SUV requires 5 liters. The checking method is quite simple: after adding oil, open the hood, pull out the dipstick, wipe it clean, reinsert it for another measurement—if the oil level is between the minimum and maximum marks, it's safe. Underfilling oil is a serious mistake as it may cause engine overheating and cylinder scoring, leading to costly repairs. The manual specifies the recommended amount, which I always check before each maintenance since seasonal temperature changes also affect oil requirements. Developing this habit helps avoid roadside breakdowns, and I always keep a small bottle of spare oil in the car just in case.
