what gas does a 2025 honda civic take

2 min read 01-12-2024

The 2025 Honda Civic, like its predecessors, runs on regular unleaded gasoline. Specifically, it recommends using gasoline with an octane rating of 87 or higher. While higher octane fuels won't harm the engine, they won't provide any performance benefits in this vehicle and are unnecessary expense.

Understanding Octane Ratings

Octane rating measures a fuel's resistance to knocking or pinging. Knocking is the uncontrolled explosion of the air-fuel mixture in the engine's cylinder. Higher octane fuels are more resistant to knocking, which is beneficial in high-performance engines with higher compression ratios. However, the 2025 Honda Civic's engine is designed to run optimally on regular (87 octane) gas.

Why 87 Octane is Recommended

Honda engineers design the 2025 Civic's engine for optimal performance and fuel efficiency with regular unleaded gasoline. Using a higher octane fuel like premium (91 or higher) won't improve horsepower or fuel economy in this specific car model. In fact, it's simply an unnecessary added cost.

Fueling Your 2025 Honda Civic

When filling your 2025 Honda Civic, look for pumps labeled "Regular Unleaded" or displaying an octane rating of 87. Avoid using fuels labeled "Midgrade" or "Premium" unless specifically recommended by Honda for a particular engine variant (which is not the case for the standard 2025 Civic models).

Other Fuel Considerations

Beyond octane, maintaining your fuel system is important for optimal performance. Consider using fuel additives designed to clean fuel injectors and prevent the buildup of deposits. These can help maintain engine efficiency and prevent potential problems down the line.

What about Ethanol?

Most regular unleaded gasoline contains ethanol, a biofuel. The 2025 Honda Civic is compatible with gasoline containing ethanol blends up to 10%. Check your owner's manual for the specific recommendations, but blends of up to E10 are generally acceptable.

Where to Find the Information

Always refer to your owner's manual for the most accurate and up-to-date information regarding the recommended fuel type for your specific 2025 Honda Civic. The information provided in the fuel filler door is also a good reference point.

Conclusion

To summarize, the 2025 Honda Civic uses regular unleaded gasoline with an octane rating of 87. Sticking to this recommendation will ensure optimal performance and fuel efficiency for your vehicle. Remember to consult your owner's manual for any specific details or recommendations for your individual car. Using higher-octane fuel is unnecessary and a waste of money for this model.
