The 2022 Honda Accord runs on regular unleaded gasoline with an octane rating of 87 (AKI) or higher. Premium fuel is not required for normal operation, though you can use higher-octane gas if you prefer or if you want to test performance under specific conditions.
Both available engines—the 1.5-liter turbo and the 2.0-liter turbo—share the same octane guidance: 87 octane or higher. This article explains what that means for daily driving and when higher-octane fuel might be considered.
Fuel requirements by engine
Before listing the engines, note that the two turbocharged options in the 2022 Accord use the same minimum octane requirement.
- 1.5-liter turbocharged engine: Regular unleaded gasoline with an octane rating of 87 or higher is suitable.
- 2.0-liter turbocharged engine: Regular unleaded gasoline with an octane rating of 87 or higher is suitable.
In practice, 87-octane gas covers daily driving for both engines, and there is no mandatory premium fuel for normal use.
Official guidance
Honda’s official guidance states that regular unleaded gasoline with an octane rating of 87 is sufficient for both engines and that premium fuel isn’t required to operate the vehicle under typical conditions.
Premium fuel considerations
Before discussing potential benefits, consider how Honda frames the role of premium fuel in everyday driving.
- Premium gasoline (91–93 octane) is not required for daily use. The engines’ knock sensors adjust timing to prevent knocking, so most drivers won’t see a meaningful improvement in power or mpg from using higher-octane fuel in normal driving.
Bottom line: using premium gasoline in a 2022 Accord is optional and unlikely to deliver noticeable gains in typical everyday driving.
Summary
For the 2022 Honda Accord, regular unleaded gasoline with an octane rating of 87 or higher is appropriate for all trims and engine options. Premium fuel is not required, though you may opt to use higher-octane gas if you prefer, understanding that most drivers won’t see a significant performance or efficiency advantage.
