Regular unleaded gasoline with an octane rating of 87 or higher. Premium is not required for normal operation.
The 2017 Honda Accord offers two turbocharged engines (a 1.5L and a 2.0L) and is designed to run on standard gasoline. In the United States and most markets, you can fill with regular gasoline containing up to 10% ethanol (E10). Always check your owner’s manual and the fuel cap label for the exact specifications for your trim and region.
Fuel specifications for the Accord engines
Key guidance on octane and ethanol content for the 1.5T and 2.0T engines.
- Regular unleaded gasoline with an octane rating of 87 (AKI) or higher is appropriate for both engine options.
- Using higher-octane fuels (89, 91, or 93) is optional and may offer marginal benefits in certain conditions, but it does not typically unlock noticeable horsepower gains in everyday driving.
- Gasoline containing up to 10% ethanol (E10) is generally acceptable; avoid fuels with higher ethanol content unless your region’s specifications allow it.
In practice, most drivers will experience equivalent performance on 87 octane Regular, with higher-octane fuels providing little to no real-world benefit for ordinary use.
What to avoid and fueling reminders
Important cautions to protect the engine and emissions system when fueling the Accord.
- Do not use diesel fuel or gasoline intended for engines with different fuel systems.
- Avoid fuels with ethanol content higher than 10% unless your region or owner’s manual specifies otherwise.
- Avoid adding aftermarket fuels or contaminant additives that aren’t approved for gasoline engines.
Sticking to these guidelines helps maintain fuel-system integrity and emissions performance for the 2017 Accord.
Practical fueling tips
Tips to ensure smooth fueling and optimal performance over the life of the vehicle.
- Always verify the exact fuel requirements for your trim and market in the owner’s manual or on the filler-cap label.
- Use reputable gasoline stations to minimize contaminants and impurities.
- Try to refuel before the tank gets very low to reduce the risk of sediment draw from the tank bottom.
Following these practices supports consistent performance, efficiency, and the longevity of the engine and fuel system.
Summary
The 2017 Honda Accord runs on regular unleaded gasoline (87 octane or higher) and generally accepts up to 10% ethanol (E10). Premium fuel is not required for normal operation, and the vehicle is designed to perform well on standard gasoline. Always consult the owner’s manual or the fuel-cap label for model- and region-specific guidance, and avoid diesel or fuels with ethanol content beyond what is recommended. With the correct fuel type, the Accord delivers reliable performance and efficiency across its engine options.
