What specification of engine oil is suitable for the Fit?
2 Answers
The Fit uses engine oils with specifications 5W-20, 5W-30, and 5W-40. The classification and usage environments of engine oils are as follows: Classification of engine oils: Engine oils are divided into three types: full synthetic oil, semi-synthetic oil, and mineral oil. Full synthetic oil has the longest service life, typically requiring replacement every 10,000 kilometers. Semi-synthetic oil can be replaced every 8,000 kilometers, while regular mineral oil should be replaced earlier. Usage environment of engine oils: For the Honda Fit in very cold climates, 5W-20 engine oil can be used. However, once the temperature exceeds 20 degrees Celsius, the oil must be replaced immediately to avoid engine damage.
As a long-time Fit owner, I've consistently used 0W-20 full synthetic oil. This specification is highly recommended, especially during cold northern winters when its quick low-temperature starting ensures smooth engine operation. The high-temperature viscosity of 20 provides thin protection that saves fuel, averaging about 10% better mileage. Honda's manual specifies API-certified oils like SP grade to protect valves and pistons. I change oil every 5,000 km to prevent carbon buildup from damaging the engine. You can get it at dealerships or buy reputable brands like Mobil – just don't cheap out on inferior products. Oil selection should match driving habits: 5W-30's slightly thicker viscosity suits frequent highway driving for better durability, while 0W-20 works better for stop-and-go city traffic. Wrong oil choices lead to noisy engines and poor fuel economy, so regularly checking oil level and color is crucial.
