Is it necessary to use 95 octane fuel for the Vezel?
3 Answers
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. Below is a relevant introduction: Fuel grades: The so-called 95 octane and 92 octane gasoline have no difference in fuel quality. It should not be assumed that a higher octane number indicates better gasoline quality. In fact, the main difference between 92 octane and 95 octane gasoline lies in their octane values. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. Notes: If the car is equipped with a turbocharged engine, it is recommended to use 95 octane gasoline. For naturally aspirated engines, 92 octane gasoline is recommended. The minimum fuel grade required for the engine can be found on the inside of the fuel tank cap, where it is specifically indicated. It is advisable to use the fuel grade officially recommended for the car.
I've been driving the Vezel for several years, and every time I check the user manual, it clearly recommends using 92-octane fuel, not necessarily 95. Unless there are specific engine issues, such as a high compression ratio, higher octane fuel is advised. Normally, 92-octane is more cost-effective and widely available at gas stations, so there's no need to go out of the way to find 95. The Vezel's engine design is quite durable, and regular fuel is perfectly adequate for daily driving—no need to waste extra money. If you insist on using 95-octane, you won't notice any difference in the short term, but over time, it might just waste fuel and cost more. It's better to invest in regular engine maintenance instead. In short, just follow the crowd and use 92-octane—don't overcomplicate it. If you're really concerned, consult a 4S shop for peace of mind.
As a budget-conscious person, I believe using 92-octane gasoline for the Vezel is perfectly sufficient. 95-octane fuel is significantly more expensive, saving me dozens of yuan per tank. For frequent drivers like me, this adds up to hundreds in annual savings. Besides, the Vezel isn't a high-performance vehicle—its engine doesn't require high-octane fuel to prevent knocking. Using 95-octane is simply burning money. For city driving, 92-octane works just fine, and the savings could be better spent on oil changes or tires. Even on highways, the difference is negligible as long as the fuel quality isn't substandard. Fuel efficiency depends more on gentle throttle habits than octane ratings—using 95-octane won't improve mileage or power, just add unnecessary expenses. There's really no need for the extra hassle.
