The Honda Fit uses 5w40 fully synthetic oil. The functions of engine oil are: 1. To reduce friction and high temperatures; 2. To minimize gas leakage and prevent external contaminants; 3. To protect components from contact with water, air, and acidic harmful gases. Taking the 2020 Honda Fit as an example, it belongs to the compact car category with body dimensions of: length 4109mm, width 1694mm, height 1537mm, wheelbase of 2530mm, and a fuel tank capacity of 40 liters. The 2020 Honda Fit features a MacPherson strut front suspension and a torsion beam rear suspension. It is equipped with a 1.5L naturally aspirated engine, delivering a maximum horsepower of 131PS, maximum power of 96kW, and maximum torque of 155Nm, paired with a continuously variable transmission (CVT).

I've been driving a Honda Fit for almost ten years, always using 0W-20 synthetic oil. The manual recommends this viscosity because it matches the new engine design, saving fuel and reducing noise. I use Mobil 1 brand, changing it every 8,000 kilometers, remembering to replace the oil filter simultaneously to filter out impurities. Even in summer heat, it's no problem—the thin oil flows well and protects precision components. If you mistakenly use 5W-30 oil, fuel consumption may increase by 10%, as my neighbor tried, and the engine noise gets louder. After regular maintenance, the car accelerates more smoothly, and cold starts in winter won't hesitate. The key is to buy genuine oil—don't cheap out and use recycled oil, or it will damage piston rings and shorten engine life. From my experience, the oil choice for a Honda Fit directly affects driving comfort. I recommend checking the oil level every six months to ensure safe driving.

From the perspective of daily vehicle maintenance, the recommended oil grade for the Honda Fit is generally 0W-20 or 5W-20 synthetic oil, depending on the model year. For instance, newer models post-2018 tend to favor 0W-20 for improved fuel efficiency. When changing oil, always opt for certified oils, such as those with API SP rating, which offer better protection. I often advise owners not to exceed a 10,000-kilometer oil change interval and to regularly check the dipstick—replace the oil immediately if it turns black. Using thinner oil can reduce engine friction, but it might not be suitable for older vehicles, where 5W-30 can serve as an alternative. I’ve encountered cases where mismatched oil led to increased carbon buildup—simple maintenance can prevent major repairs. Temperature also plays a significant role; in northern winters, prioritize oils starting with 0W to ensure smooth cold starts. Choose reliable brands like Shell or Castrol to guarantee lubrication quality and extend the vehicle’s lifespan.

As a veteran driver with over 20 years of experience, I remember the first-generation Fit used 5W-30 oil, but most new models now specify 0W-20 synthetic oil. Technological advancements have made oils more efficient. Every time I change to this oil in my Fit, the fuel consumption drops by half a liter per 100 kilometers. Lower viscosity has many benefits - it can penetrate small engine clearances, reduce wear, and extend engine life. Don't neglect oil change frequency; the manual says every 10,000 km, but I insist on changing every 7,000 km to prevent deposit buildup. Using the wrong oil type like thicker viscosity can cause sluggish power output. Brand selection is also important - synthetic oils last longer than mineral oils, and those with detergents help keep the system clean. Using 5W-30 in summer is acceptable, but 0W-20 is recommended for long-term use. Checking oil is simple - pull the dipstick when the engine is cold, and top up when low to avoid overheating damage.
