Honda Spirior can use SM grade 5W-30 engine oil. Below is detailed information about the Spirior: 1. Overview: The Spirior pioneered the "Premium Sport" design concept, incorporating multiple world-class technologies. The 'S' in Spirior stands for Sporty-Premium-Sedan, representing a high-end sports sedan. The 'R' signifies Research-and-Development, indicating ongoing innovation. The Honda Spirior shares its fundamental platform with the Acura TSX and the European Accord. 2. Additional Information: As a mid-to-high-end sedan, the Spirior's interior design does not deliberately cater to Chinese consumer preferences but instead focuses on a technological and sporty aesthetic. The driver-centric dashboard features meticulous layering and rational layout.

I have been driving a Honda Spirior for over five years and always stick to using 0W-20 synthetic oil, which is the recommended grade in Honda's official manual. This oil has low viscosity, providing better engine protection, especially during cold winter starts without any hesitation. I find that changing it every 5,000 kilometers or six months is optimal—too frequent changes waste money, while delaying it too long leads to carbon buildup. Using Honda-certified brands like Shell or Mobil ensures stable performance; don’t cut corners with off-brand oils, as they can cause increased engine noise and higher fuel consumption. Regularly checking the oil level during maintenance is simple yet practical, helping your car run longer and more reliably.

As someone who frequently works on cars, I recommend using 0W-20 synthetic oil for the Spirior, which meets API SN standards. Honda engines are designed to match this specification. Lower viscosity means better lubrication, reduced friction, and extended engine life. I've seen owners use the wrong 5W-30 oil, resulting in increased fuel consumption and even malfunctions. It's recommended to change the oil every 8,000 kilometers using OEM-approved brands like Castrol, and avoid extended use in high-temperature environments. Choosing the right oil can save on repair costs. If you're doing it yourself, pay attention to matching the oil filter. Beginners are better off seeking professional shops.

My Honda Spirior is a daily commuter car, and using 0W-20 engine oil is perfectly fine as clearly stated in the manual. Oil changes are simple, done every six months, and not costly. The advantage of choosing synthetic oil is its high-temperature resistance, so I don’t have to worry about engine overheating even when using the AC in summer. I also pay attention to the brand, sticking with Honda’s own or Mobil for reliability. Don’t forget to check the dipstick—if the oil level is low, top it up promptly. This ensures smoother driving, better fuel efficiency, and enhanced safety.
