What grade of engine oil should be used for the Fit?
3 Answers
The Fit uses SNOW20 engine oil. The functions of engine oil are: lubrication, auxiliary cooling, cleaning, sealing and leak prevention, rust and corrosion prevention, shock absorption, and anti-wear. Taking the 2021 Fit as an example, it is a compact car with body dimensions of: length 4109mm, width 1694mm, height 1537mm, wheelbase of 2530mm, and a curb weight of 1088kg. The 2021 Fit is equipped with a 1.5T turbocharged engine, with a maximum horsepower of 131PS, maximum torque of 155Nm, maximum power of 96kW, and is paired with a continuously variable transmission.
I'm a Fit owner and have been driving it for several years, previously struggling with the oil grade issue. The Fit is quite sturdy, but its engine is more delicate. The manufacturer recommends using 5W-20 or 0W-20 synthetic oil, and big brands like Shell or Mobil are fine. Never use high-viscosity oils like 10W-40, as they can make cold starts difficult in winter and may increase fuel consumption in summer. I change the oil every 5,000 kilometers along with an oil filter check, and the engine response feels smooth. If you live in a cold northern region, 0W-20 is better for low-temperature protection, while 5W-20 is more cost-effective for year-round use in the south. Remember to check the owner’s manual to confirm the grade—don’t skimp on this small expense, as using the wrong oil can cause serious trouble, leading to premature engine wear.
From a car repair perspective, compact cars like the Fit are best suited for low-viscosity engine oil. We recommend fully synthetic oils with 5W-20 or 0W-20 grades. These low-viscosity oils have excellent fluidity and can quickly form a protective layer during engine startup, reducing friction wear. The Fit's engine has a compact design, and using high-viscosity oil would actually slow down piston movement, potentially increasing fuel consumption by about 10% over time. When selecting oil, also check the API rating - SN or SP grades are preferable due to their strong oxidation resistance. I recommend checking the dipstick and fluid level during every maintenance service, and don't exceed the 8,000 km oil change interval. Semi-synthetic oil is acceptable, but make sure it meets the manufacturer's specifications to avoid potential oil passage blockage.
