Should the Accord use 92 or 95 octane gasoline?

The Accord should use 95 octane gasoline, which has higher anti-knock performance than 92 octane gasoline. Taking the 2021 Accord as an example, it has a fuel tank capacity of 56 liters. The vehicle dimensions are: length 4893mm, width 1862mm, height 1449mm, with a wheelbase of 2830mm and a curb weight of 1495kg. The 2021 Accord is classified as a midsize sedan, featuring a front MacPherson strut independent suspension and a rear multi-link independent suspension. It is equipped with a 1.5T turbocharged engine delivering maximum power of 194PS (143kW) and peak torque of 260Nm, paired with a continuously variable transmission.

To be honest, I've been driving a Honda Accord for a long time, and this car runs perfectly fine on 92 octane gasoline. Honda's engines are quite reliable and designed with fuel efficiency in mind—92 octane fully meets daily needs. Some people might mistakenly think 95 octane is superior, believing it boosts performance or saves fuel, but for a standard Accord engine, using 95 octane offers virtually no extra benefits—just higher costs. Moreover, if the engine's compression ratio isn't designed for it, higher-octane fuel could even cause combustion issues, potentially harming the engine long-term. The key is to follow the owner's manual—Honda's official recommendations are clearly stated there, and sticking to them is the safest approach. Choosing the right gasoline not only saves money but also extends the car's lifespan. Don’t waste cash on unrealistic expectations.

When it comes to gasoline octane ratings, the difference between 92 and 95 lies in the octane level, with 95 having better anti-knock properties, making it suitable for high-performance engines like turbocharged vehicles. However, most Honda Accord models are naturally aspirated and originally designed to use 92-octane fuel. Using it won't harm the car or increase fuel consumption. Unless the manual specifies a higher octane requirement, 95-octane is unnecessary; upgrading offers no real benefit. I've also noticed some car enthusiasts believe 95-octane can enhance acceleration, but actual tests show minimal differences, not worth the extra cost. In short, follow the manual for peace of mind—92-octane is the most suitable choice—don't complicate things for yourself.

Using 92-octane gasoline for the Accord is sufficient, no need to overthink it. Honda cars are known for their practicality, and their engines are not picky about fuel—92-octane is enough. The manual will also recommend this, so following it won't go wrong. Don't assume that 95-octane is superior; using the wrong fuel might lead to minor issues, such as unnecessary expenses. Remember to check the manual for updates regularly to make maintenance easier.
