Should Mazda CX-30 use 92 or 95 octane gasoline?
2 Answers
Mazda CX-30 can use either 92 or 95 octane gasoline. 92 octane gasoline: Suitable for mid-range vehicles (with relatively low compression ratio). Considering the current status of automotive gasoline production, storage, transportation, and usage, as well as the technical transformation needs of oil product manufacturers and automotive emission control technologies, its main indicators are comparable to current European standards. It meets the requirements of China's Phase V vehicle pollutant emission standards, helping to reduce vehicle emissions and playing a significant role in environmental protection and improving air quality. 95 octane gasoline: Used for engines with higher compression ratios. Using the wrong octane can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. Do not blindly choose gasoline based on compression ratio; instead, follow the manufacturer's recommendations for refueling.
Last year, I drove my CX-30 over 20,000 kilometers and initially struggled with fuel octane choices. The manual clearly states that unleaded gasoline with an octane rating of 92 or above is suitable—the Skyactiv engine truly isn't picky. However, in practice, 95-octane fuel delivers quicker power response, especially noticeable when climbing hills where the throttle feels more responsive. Crunching the numbers, 95-octane costs about 0.5 yuan more per liter than 92. Based on a monthly mileage of 800 km, that adds up to just over 500 yuan annually. For daily commuting, 92-octane is perfectly adequate, but when tackling mountain roads on weekends or carrying full loads, filling up with 95 reveals subtle advantages. Just don’t fall for gas stations pushing 98-octane—it’s completely unnecessary.
