What is the purpose of the oil grade in Honda maintenance?

Oil grades represent different categories of engine oil. Numbers such as 20, 30, 40, and 50 indicate the viscosity of the oil, with higher numbers representing thicker oil, which is suitable for use in high-temperature regions. The terms 0W, 5W, 10W, 15W, 20W, and 25W, where "W" stands for winter, indicate that the smaller the number before the "W," the better the low-temperature viscosity. Below is an introduction to Honda engine oil: 1. Engine oil is divided into three types. The first is conventional mineral oil, which should be replaced after the vehicle has traveled 5,000 km. The second is semi-synthetic oil, which should be replaced after the vehicle has traveled 7,500 km. The third type is fully synthetic oil, which should be replaced after the vehicle has traveled 10,000 km. Comparatively, fully synthetic oil is more cost-effective. 2. Honda turbocharged engines use fully synthetic oil. Fully synthetic oil has a longer maintenance cycle, lasting one year or up to 10,000 km, and provides better lubrication for the engine, making it more suitable for turbocharged engines.
Hi, regarding the oil grade in Honda maintenance, it actually refers to the oil viscosity rating, such as 5W-30 or 0W-20. These numbers help determine the oil's flow performance at different temperatures. The number before the W indicates the low-temperature viscosity in winter—the smaller the number, the easier it is to lubricate during cold starts. The number after represents the high-temperature viscosity, ensuring reduced friction during engine operation. For Honda vehicles, the manufacturer recommends specific grades like 0W-20 to improve fuel efficiency and protect precision components. I often remind my friends that using the wrong grade can lead to unstable oil pressure or increased engine wear, ultimately raising repair costs. During maintenance, it's best to stick to the manual's guidance, changing the oil every 5,000 to 10,000 kilometers while checking if the oil color has turned black to avoid deposit issues. Choosing the correct oil grade not only makes the car run smoother but also extends engine life, saving both hassle and money.
As a Honda owner, I deeply appreciate the importance of engine oil viscosity grades: they directly impact daily driving experience. Using the recommended grade like 5W-30 ensures quick starts and smooth acceleration, especially avoiding sluggishness in cold weather. However, using higher viscosity oil such as 10W-40 in a vehicle designed for 0W-20 may increase fuel consumption and potentially cause abnormal noises. During each maintenance, I personally verify the correct grade to prevent mechanics' selection errors. This practice not only protects the engine but also saves fuel costs, as incorrect viscosity increases resistance and accelerates component wear over time. I've also learned that Honda engineers optimize their engines for lower viscosity oils, working in tandem with air filtration systems to ensure cleaner emissions. Now it's become my routine to consult the owner's manual or mobile app before maintenance, selecting brand-matched oil products for safer and more comfortable driving.
