Is it suitable for the Mazda 3 Axela to use 92 or 95 octane gasoline?

It is suitable for the Mazda 3 Axela to use 92 octane gasoline. Gasoline is a volatile and flammable hydrocarbon mixture liquid distilled and cracked from petroleum, which can be used as fuel. Taking the 2021 Mazda 3 Axela as an example, its body dimensions are: length 4295mm, width 1798mm, height 1616mm, wheelbase 2570mm, and fuel tank capacity 40L. The 2021 Mazda 3 Axela is equipped with a 1.3T turbocharged engine and a CVT continuously variable transmission, with a maximum power of 121 kW, maximum power speed of 5600 rpm, maximum torque of 240 N·m, maximum torque speed ranging from 1500 to 4000 rpm. Its drive mode is front-wheel drive, with a front suspension using MacPherson independent suspension and a rear suspension using a compound torsion beam non-independent suspension.
I’ve been driving my own Mazda3 Axela for over a year, and I initially struggled with this issue too. The user manual clearly recommends using 92-octane fuel, so I’ve stuck with it. My fuel consumption has remained stable at around 7L/100km, and the car runs smoothly. While 95-octane fuel is more expensive and has a higher octane rating, which may offer better anti-knock performance, it’s not really necessary for this car unless you frequently drive at high speeds or face particularly rough road conditions. My practical experience is that the money saved is better spent on maintenance, such as using higher-quality engine oil to improve engine longevity. In short, 92-octane is perfectly adequate for normal driving—don’t waste money following the trend of pricier fuel.
The octane rating of car fuel is related to engine efficiency. The Mazda 3 (Axela) uses a high-compression ratio naturally aspirated engine, and the factory design allows it to run smoothly on 92-octane fuel. While 95-octane may slightly improve responsiveness, the higher cost may not justify the marginal benefit. It's important to use qualified fuel in daily driving to avoid carbon buildup caused by low-quality fuel. For example, my neighbor, who has driven several car models, mentioned that the Mazda 3's fuel efficiency is its key advantage, and 92-octane is perfectly sufficient—there's no need to spend extra on higher-octane fuel. Always follow the manual's recommendations to avoid mistakes.
