Is it better to use 92 or 95 octane gasoline for the Mazda3 Axela?
2 Answers
It is better to use 95 octane gasoline for the Mazda3 Axela. Below are some relevant introductions about refueling cars: 1. If you are unsure about which type of gasoline to use for your car, the simplest method is to open the fuel tank cap, where you will find a recommendation. Following this suggestion is the most authoritative advice. 2. The gasoline octane rating is the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the octane rating, the stronger the anti-knock performance. Isooctane has good anti-knock properties, and its octane value is set at 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, so its octane value is set at 0. For example, if the gasoline's octane rating is 90, it means that this gasoline has the same anti-knock performance as standard gasoline containing 90% isooctane and 10% n-heptane.
I’ve been driving my Mazda3 (Axela) for several years and always use 92-octane fuel—it’s really cost-effective. 92-octane is significantly cheaper, and with fuel prices constantly fluctuating, saving where you can makes sense. The Mazda3’s engine is designed to run optimally on 92-octane, and after years of use, I’ve had zero issues—acceleration remains smooth. Some friends claim 95-octane is better, but I’ve tested it a few times and noticed minimal difference, with no real improvement in fuel efficiency. Economically, 92-octane is perfectly sufficient; over time, it saves thousands in fuel costs. Also, don’t stress about engine knocking—modern cars are smart, and the ECU adjusts automatically. If unsure, just check the manual: Mazda officially recommends 92-octane, so upgrading is an unnecessary expense. For daily commuting, 92-octane is the practical choice, paired with affordable maintenance—ideal for value-conscious owners like us.
