The minimum fuel grade required for the Vezel is 92 octane, so there is no need to use 95 octane gasoline. Using 92 octane gasoline is sufficient to meet the engine's operational requirements. Generally speaking, Japanese cars typically use engines that require 92 octane fuel, with only some turbocharged engines requiring higher-grade 95 octane gasoline. Definition of gasoline grades: Gasoline grades represent the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher grades are not necessarily better; the appropriate gasoline grade should be chosen based on the engine's compression ratio. Misconceptions about gasoline usage: Some people fall into the misconception of preferring higher-grade gasoline, and some even consider the gasoline grade as a standard for fuel purity and quality. This is a mistaken notion. In fact, the grade of gasoline only indicates the octane value and should never be confused with purity and quality.

I've been driving the Vezel for two years and have studied this issue carefully. The manual clearly states that 92-octane gasoline is sufficient, so from an economic perspective, there's really no need to use 95. For city commuting, 95-octane is significantly more expensive, costing dozens to hundreds more per month without necessarily providing tangible benefits. The Vezel's engine isn't a high-performance version, and 92-octane already meets normal requirements. Unless you frequently drive long distances or on mountain roads where 95-octane's higher knock resistance can reduce engine knocking and slightly improve acceleration, the difference in daily driving is negligible. I've tried both fuels - 95 only performs slightly better when oil temperatures are high, but overall it's not worth the extra cost. The money saved can be better spent on regular , which is more cost-effective than upgrading fuel. Remember, don't be fooled by gas station promotions - following the manual is the safest approach.

Having driven for over a decade, I've always owned Japanese cars including the HR-V. From a performance perspective, occasionally using 95-octane fuel makes the engine respond slightly faster with smoother acceleration, but it doesn't mean you must use it long-term. The HR-V's engine is designed to run perfectly on 92-octane - higher-octane 95 mainly prevents knocking under high-temperature or carbon-deposit conditions. In real-world tests, there's negligible urban fuel consumption difference between 95 and 92, so I normally just use 92 to save money. Friends suggest premium fuel extends engine life, but my experience proves regular oil changes and air filter replacements matter more for engine health. The savings allow me to drive hundreds of extra kilometers annually.

As an average car owner, safety is my top priority. The Vezel manual specifies 92-octane gasoline, and using 95 is not necessary. Higher octane fuel can reduce the risk of knocking, but modern engine electronic controls are quite advanced, making 92-octane sufficiently safe in most cases. There's no need to spend extra on 95 unless your car has carbon buildup issues. I stick with 92 and have never encountered any problems. When refueling, choosing reputable stations to ensure fuel quality is more important than the octane rating.

Having driven the Vezel for three to four years, based on experience, using 92-octane fuel is sufficient. I've tested with 95-octane, which provides slightly better power but the cost increases quickly, making it not worth it. Occasionally using it for carbon deposit cleaning is acceptable, but long-term use is wasteful. For city driving, 92-octane works perfectly fine. On highways or long trips, 95-octane might help but isn't necessary. Saving the money for minor is wiser.

From a practical daily life perspective, using 95-octane fuel for the Vezel is unnecessary. The manual recommends 92-octane, which is perfectly adequate for regular use. 95-octane is more expensive, costing a few cents more per liter, which adds up to significant extra expenses over a year. The performance improvement is negligible, with benefits only noticeable in extreme conditions like high temperatures. I consistently use 92-octane to save money and for convenience. Paying attention to the cleanliness of the gas station is more crucial.
