For a K2, the engine oil generally requires about 3-3.2 liters per change. Below are the functions of engine oil and its classification: Functions of engine oil: Lubrication and friction reduction, auxiliary cooling, cleaning, sealing and leak prevention, rust and corrosion prevention, shock absorption. Classification of engine oil: Engine oil is divided into three categories: conventional mineral oil, semi-synthetic oil, and full synthetic oil. Mineral oil is the most commonly used lubricant on the market, derived from the distillation of petroleum during the refining process. Semi-synthetic oil is made from semi-synthetic base oil, which is a product of hydrogenation and cracking technology applied to mineral oil, consisting of a 4:6 ratio of mineral oil to full synthetic oil. Semi-synthetic oil is very close in purity to full synthetic oil but is slightly more expensive than mineral oil, making it an ideal transitional product between mineral oil and synthetic oil. Full synthetic oil is the highest grade of engine oil, derived from ethylene and propylene dispersed from natural gas or crude oil, and undergoes complex chemical reactions such as polymerization and catalysis to form a lubricating fluid composed of large molecules.

















When I change the oil for my K2, I usually add around 3.8 liters, based on my experience with the 2018 model. However, the amount may vary slightly for different year models, so it's recommended to check the user manual first. If the oil level is too high, the oil pressure will increase, potentially causing oil leaks or damaging the seals. On the other hand, insufficient oil leads to inadequate lubrication, causing the engine to overheat and wear out. After each oil change, I start the car and let it run for a few minutes to circulate the oil, then check the oil level with the dipstick when the engine is cold to ensure it's between the min and max marks. The maintenance interval is every 5,000 kilometers for an oil change, using the appropriate grade like 5W-30, which keeps the car running smoothly and improves fuel efficiency. Developing the habit of manual checks can save a lot on repair costs.

The oil capacity of the K2 typically ranges between 3.5 to 4 liters. For my 2017 model with a 1.6L engine, adding 3.8 liters is most appropriate, but always refer to the manual as the ultimate guide. Before each oil change, I worry about overfilling because excessive oil levels can damage the sealing system, causing the engine to smoke or run unevenly. I make it a habit to park on level ground, wait for the engine to cool down, and then check the oil level multiple times with the dipstick for accuracy. A friendly reminder: if the engine has been modified or additives are used, the capacity might vary, but for stock vehicles, this amount is just right. Regular oil maintenance helps avoid unnecessary maintenance costs.

When I first changed the oil for my K2, the manual stated to add approximately 3.8 liters. The actual operation is simple: prepare a 4-liter oil container, pour in 3.5 liters first and check the dipstick level, then top up if needed. Be careful not to overfill or underfill – insufficient oil will cause strange engine noises, while too much oil will result in sluggish acceleration. If you're checking the oil level yourself, make sure the car is parked on level ground and the engine is off. Pull out the dipstick, wipe it clean, reinsert it, and the normal level should be in the middle zone. Regular oil changes extend your car's lifespan.

My K2 has been running for five years, and adding exactly 3.8 liters of engine oil meets the standard recommendation. The key to checking the oil level is to park the car, wait a few minutes, then pull out the dipstick to see if it's within the range. Adding too much or too little can affect performance, such as increased fuel consumption or difficulty starting. Choosing the right type of oil and the correct capacity during maintenance has kept the car running smoothly.

The oil capacity for the K2 is typically 3.8 liters, and accurate oil changes protect the engine. Before changing, drain the old oil completely, then pour in the new oil slowly to avoid spills. Use the dipstick to monitor levels during the process to prevent mistakes. Ensure the new oil type matches the requirements, such as synthetic oil, to keep the engine clean and efficient. Regular checks and good habits ensure your car lasts longer.
