What brand of engine oil is suitable for the Fit?
4 Answers
For the Honda Fit, it is recommended to use Mobil Super 1000 or Castrol Magnetec engine oil with a viscosity grade of 10W-30. Below is an introduction to the engine oil specifications for the Honda Fit: 1. 10W30 refers to the SAE standard viscosity value, indicating that this oil is a multi-grade oil. 2. The 'W' stands for WINTER, and the number before the 'W' represents the oil's flow performance at low temperatures—the smaller the number, the better the cold-start performance. The number after the 'W' indicates the oil's stability at high temperatures—the larger the number, the better the high-temperature stability. 3. The smaller the number before the 'W', the lower the oil's low-temperature viscosity, the better its low-temperature flow performance, and the lower the minimum applicable temperature.
Over the years of driving my Fit, I've gained some insights into engine oil. For this small-displacement Earth Dreams engine, sticking faithfully to 0W-20 viscosity full synthetic works best. Honda's certification is paramount - just look for GF-6 or API SP markings on the bottle. I always keep Shell Helix Ultra on hand; its cleaning properties are perfect for direct-injection engines prone to carbon buildup. Mobil 1 Extended Performance series offers good longevity, capable of about 10,000 km. Idemitsu ZEPRO's fuel-saving effect is visibly noticeable, especially suitable for city commuting. The key is not to cheap out on no-name brands - an engine's quiet operation and throttle response never lie. Always inspect the condition of used oil during oil filter changes - it tells you whether the oil is suitable.
Last time I saw the maintenance list for the Fit at the 4S shop, the factory recommendation was 0W-20. In fact, the three major Japanese brands are quite compatible: Idemitsu has a particularly large installation volume in Japanese cars, Mobil offers faster power response, and Shell excels at cleaning carbon deposits. The key is to look for the A5/B5 or ILSAC GF-6 certification standards. Don’t worry about whether it’s a big brand or a small one—never use any oil without these two certifications. My third-gen Fit used to run on Castrol Edge, but the cold start noise was a bit loud. After switching back to Idemitsu, it improved significantly. For older cars, pay attention to oil consumption—checking the dipstick every 5,000 kilometers is more reliable.
The engine oil for the Fit depends on the model year. For the third-generation and later Earth Dreams engines, low-ash oil must be used; otherwise, the GPF may get clogged, which is troublesome. Recently, I switched to the Idemitsu ZEPRO ECO series for my 2019 model, which has the JASO GLV-1 certification on the bottle and is particularly fuel-efficient. Actual tests showed a reduction of 0.3 liters per 100 kilometers. It's recommended to use 0W-20 full synthetic oil, as 5W-30 can increase fuel consumption in hot weather. Be cautious of counterfeit products when shopping online—JD.com's self-operated stores or Tuhu's factory outlets are more reliable. Don't exceed an oil change interval of 8,000 kilometers, as the Earth Dreams direct-injection engine is sensitive to oil degradation.
