Is it necessary to use 95-octane gasoline for the Edge?

[GenevieveLynn]

It is not necessary. When refueling the Edge model, unleaded regular gasoline with an octane rating of at least 92 should be used. Below is an introduction to the relevant content: Refueling: When refueling, you can choose either 92-octane or 95-octane gasoline. The proportion of isooctane in 92-octane gasoline is much lower than that in 95-octane gasoline. The higher the octane rating, the higher the isooctane value. The higher the proportion of isooctane, the better the gasoline's anti-knock performance. Mixing gasoline: If the vehicle has been using 92-octane gasoline, it can be mixed with 95-octane gasoline, although the anti-knock performance will differ. In other words, lower-octane gasoline can be mixed with higher-octane gasoline, but gasoline that has been consistently using 95-octane cannot be mixed with 92-octane gasoline. This means higher-octane gasoline should not be mixed with lower-octane gasoline, except temporarily in emergencies. After mixing, fuel additives can be added for cleaning purposes.

I've been driving my Edge for over three years, always using 92-octane gasoline, and it runs smoothly without any issues. The manufacturer's manual recommends 87-octane fuel, which is equivalent to our domestic 92-octane, and it's perfectly adequate. Using 95-octane is significantly more expensive, costing over one yuan more per liter, which can save you more than ten yuan in pocket money each month. Of course, if you occasionally want to enjoy a bit more, adding some 95-octane might make the throttle response feel quicker, especially on the highway, but it's not necessary. I know many Edge owners who use 92-octane for daily commuting, saving money and driving with peace of mind. The key is to base it on your driving habits; regular fuel is sufficient for city traffic jams, don't be fooled into thinking you need to use more expensive fuel. Remember, regular maintenance is more important than using higher-octane fuel; spending money on oil changes is a wiser investment.

From a technical perspective, the Edge's engine is designed for regular gasoline with an octane rating around 87. While 95-octane fuel offers better anti-knock properties and can reduce potential knocking issues, the Edge's relatively low compression ratio makes this largely unnecessary. Based on observations, long-term use of 95-octane may result in slightly cleaner engines and a marginal fuel consumption reduction of less than one liter, but the actual benefits are minimal. Using 92-octane fuel won't affect the vehicle's lifespan or performance at all. I recommend checking the owner's manual, which clearly states the recommended fuel grade. Unless you frequently drive steep mountain roads where temporary use of 95-octane might provide peace of mind, there's no need to spend extra money routinely. When choosing fuel, prioritize reputable gas stations as fuel quality matters more than the octane rating itself.

As a new driver, I also struggled with this when I first got my Edge. Friends told me 92 octane is sufficient, and the manufacturer's manual recommends 87 octane. Using 95 octane is more expensive, adding up to a few hundred dollars more in annual fuel costs, which isn't really worth it for a family car. Occasionally trying 95 octane, I didn't notice much difference—maybe a slight improvement in throttle response, but that could just be psychological. In short, the Edge handles regular gasoline with no issues, and the money saved is better spent on fuel card rewards. Just make sure to check fuel quality before filling up and avoid substandard gasoline.

From an economic perspective, 95-octane gasoline is 10% to 15% more expensive than 92-octane. With the Edge's approximately 70-liter fuel tank, filling up with 95-octane costs dozens of yuan more each time. Over the long term, this adds up to over a thousand yuan in additional annual expenses. The vehicle is designed to run optimally on 92-octane fuel, delivering stable performance and reasonable fuel consumption, making an upgrade unnecessary. Unless pursuing extreme acceleration performance—where 95-octane might offer slightly better highway performance—the cost-benefit analysis clearly favors sticking with 92-octane. The price difference could cover a minor maintenance service or tire rotation. For city driving, 92-octane is perfectly adequate, and occasional mixed use during long trips is also acceptable.

From a vehicle maintenance perspective, 95-octane gasoline burns more completely, reducing the risk of carbon deposits, which is particularly beneficial for SUVs like the Edge. However, the manufacturer's manual clearly states that 87-octane is sufficient, and using lower-octane fuel will not damage the engine. For daily use, 92-octane is perfectly fine. Only under extreme conditions, such as long-distance driving in high-temperature areas, adding some 95-octane can prevent minor knocking. The key is to maintain regular maintenance and choose fuel from reputable sources—don't skimp on quality. Using 95-octane isn't a must; it's more practical to focus on driving safety and habits, such as smooth acceleration and avoiding fully loaded uphill climbs to protect the engine.
