The engine oil specification for the Rena is 5W-20, which is the original Beijing Hyundai factory oil. For later maintenance and oil changes, you can choose international brands such as Mobil, Shell, Castrol, and Total, or domestic brands like Great Wall, Kunlun, Tongyi, and Longpan. The official manual recommends the 5W-20 specification, and any oil of the same specification can be used. The viscosity of engine oil changes with temperature, so it's important to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother for the car. The second number represents the kinematic viscosity of the oil at 100°C. A higher number means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the Rena's engine oil is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Use a special wrench to remove the oil filter; Apply some oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the engine valve cover filler port. Typically, fill up to three-quarters of the oil bottle; Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.

When someone asks me about what oil to use for the Verna, I recall the confusion I experienced when I first bought the car. After researching, I found that it usually recommends 5W-20 or 5W-30 oil, depending on the model year and region. For an office worker like me, I choose 5W-20—it starts quickly in winter and performs well in summer. Don’t forget to check the owner’s manual; it has detailed instructions. I find changing the oil myself quite simple: buy genuine oil from an auto shop and change it every 5,000 kilometers. Avoid low-quality oil, or the engine noise will increase. I also regularly check the dipstick—if the oil turns black or has impurities, it’s time for an early change. This habit has saved me a lot of money and kept my car running smoothly.

Engine oil selection is crucial for the performance of the Verna. I've learned a lot from my engineer friends. They recommend 5W-20 or 5W-30 oil, especially synthetic oil, which can reduce engine wear. The 5W represents low-temperature fluidity, while the 20 or 30 after the W indicates the high-temperature protection grade. Choosing the right viscosity is important: in cold regions, 5W-20 starts up faster; in high-temperature environments, 5W-30 is more stable. I suggest selecting products with API SN or SP certification, as this can improve fuel efficiency. When changing the oil, fill it with about 4 liters and check the filter. Remember to perform regular maintenance, such as every six months, to extend the car's lifespan.

As a cost-conscious car owner, I know engine oil selection directly impacts fuel consumption. For the Verna, 5W-20 oil delivers the best fuel efficiency, especially for daily commuting. My comparative tests show inferior oils increase consumption by ~0.5L/100km, while genuine 5W-20 maintains stable performance. I always choose premium brands like Shell or Mobil (priced around tens per liter) - the upfront cost saves maintenance expenses later. Seasonal adjustments matter too: thinner oil in winter eases cold starts. Never extend oil change intervals - sticking to 5,000km changes has kept my maintenance hassle-free and budget-friendly.
