Is it better to use 92 or 95 octane gasoline for the Mazda3 Axela?
4 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.
As a driving enthusiast, I prefer using 95-octane gasoline for my Mazda 3 Axela. Its engine has a high compression ratio, and the higher octane rating of 95 provides more stable combustion, resulting in smoother acceleration. While the difference is subtle, 95-octane fuel slightly reduces vibrations during high-speed driving or sudden acceleration, enhancing the driving experience. Of course, it comes at a higher cost—a few cents more per liter—which adds up over time. The performance improvement is minimal, so don’t expect dramatic changes. The Mazda 3 Axela runs fine on 92-octane, but if I’m after that slight optimization, occasionally using 95 is a nice touch. Additionally, 95-octane fuel tends to have fewer impurities, which benefits the engine in the long run. In short, stick with 92 for practicality, but try 95 for a small upgrade.
From a technical perspective, the main difference between 92 and 95 octane gasoline lies in their anti-knock properties. 95 octane is more suitable for high-compression engines to prevent knocking. Although the Mazda3 (Axela) can use 92 octane, occasionally using 95 can optimize combustion efficiency and make the engine run slightly more smoothly. However, the actual difference is minimal. Since the manual recommends 92 octane, it's perfectly adequate, and there's no need to deliberately upgrade. The advantage of 95 octane is slightly better performance under extreme conditions like hot weather or hill climbing, while the drawback is higher cost. Using 92 octane poses no risks during normal driving. The key factor is fuel quality—choosing major brand gas stations is safer.
