Verna uses 5W-20 or 5W-30 engine oil. The functions of engine oil and precautions for use are as follows: Functions of Engine Oil: Separate the surfaces of relatively sliding parts to reduce wear, bring heat back to the oil tank and then dissipate it into the air to help the radiator cool the engine; circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, and flush away dirt generated on the working surfaces of parts through the flow of the lubricating oil. Precautions for Using Engine Oil: The selection of engine oil should be based on the requirements of the engine, and the oil chosen should match the engine. Multi-grade oil should be selected, as it has advantages such as fuel savings, long service life, and high efficiency, providing better protection for the engine; when adding oil, the amount should be slightly below the mark on the dipstick, and avoid overfilling.

The Verna I drive is an older model, and I remember the manual recommending either 5W-20 or 5W-30 oil, depending on the year and engine. For example, turbocharged engines might require higher viscosity oil. When choosing oil, climate should be considered. I live in the north where winters are cold, so 5W-20 flows faster and makes starting easier. In summer or in hot and humid southern regions, 5W-30 is more stable and prevents overheating. I always use full synthetic oil. Although it's more expensive, it has better durability, extending the oil change interval to 10,000 kilometers, saving both money and hassle. Using the wrong oil can lead to insufficient lubrication, increased engine noise, and higher fuel consumption. That's why I regularly check the dipstick and top up if the level is low, always replacing the oil filter at the same time.

As a frequent maintainer of the Verna, I recommend prioritizing the owner's manual, which specifies oil grades such as 5W-20 or 5W-30. Using the wrong viscosity can compromise protection performance, leading to increased engine wear and potential issues. I suggest using synthetic-grade oil, with API SN or higher ratings being more reliable. During , ensure the car is level and the engine is cold before checking the oil level. If the oil is too thin or too thick, lubrication efficiency drops, noise increases, and fuel consumption rises. Regular oil changes every 5,000 to 10,000 kilometers are advised, depending on driving habits—earlier changes are recommended for those who frequently drive at high speeds to ensure optimal engine longevity.

When commuting with my Verna, I found that simply using 5W-20 oil is sufficient, as the manual specifies this standard grade. isn't complicated—quickly done at the repair shop with low costs, and I bring my own oil to save expenses. Choosing oil with the right viscosity makes driving smooth and reduces noise; for high-mileage cars, trying 5W-30 can enhance protection. Oil change frequency depends on usage—for city traffic jams, change every six months to avoid dirty oil affecting performance.

I prioritize environmental protection when driving my Rio, opting for low-viscosity oil like 5W-20 to help save fuel and reduce emissions; excessively high viscosity wastes fuel and increases carbon emissions. The manual-recommended specifications consider sustainability, so I use synthetic oil to extend oil change intervals and minimize pollution. Additionally, proper oil recycling is crucial—I always take used oil to professional disposal points instead of dumping it. Using the correct viscosity also improves fuel efficiency, supporting my green driving philosophy. During maintenance, I pay attention to the certification labels on oil containers.

From my experience, the Verna's engine oil must be 5W-20 or 5W-30 to ensure safety; incorrect viscosity may cause engine overheating and potential breakdown, especially critical during cold winter starts. I use full synthetic oil for enhanced protection, avoiding excessive noise or fuel consumption spikes. Regularly changing the oil filter prevents clogging from impurities, combined with selecting high-grade API products as per the manual. Safe driving relies on proactive —proper oil with good fluidity ensures smooth winter starts without dangerous stalling.
