What gas should I put in my 2024 Honda Civic?
Use regular unleaded gasoline with an octane rating of 87 or higher; for everyday driving, 87 octane is usually sufficient, and higher-octane fuels are optional depending on driving conditions and engine response.
Octane ratings and engine compatibility
The 2024 Honda Civic lineup includes both naturally aspirated and turbocharged engines. Both typically run on regular unleaded gasoline (87 octane) without needing premium fuel for daily driving. Some drivers may notice slight improvements in throttle response or power with higher-octane fuels, but such gains are usually modest for normal use.
Turbo vs non-turbo considerations
Whether your Civic uses the 2.0-liter naturally aspirated engine or the 1.5-liter turbo, regular 87-octane fuel is generally adequate. If you own a turbo model and hear pinging or knock on regular gas, you can try mid-grade (89 octane) or premium (91 octane) to see if performance improves; if not, staying on 87 octane is fine and more economical. Always refer to your specific trim’s guidance in the owner’s manual for the most accurate recommendation.
Before the list: Quick guidelines you can use to choose gas quickly and correctly.
- 87 octane regular unleaded is suitable for all 2024 Civic trims.
- Premium fuels (89–91 octane) are optional and may offer small performance or responsiveness benefits under certain conditions.
- Gasoline with ethanol content is typically E10 in the United States; use fuels that match the ethanol content recommended in your manual and avoid blends beyond what it specifies.
Concluding for this section: In practice, most drivers will stick with regular 87-octane gasoline and only consider higher octane if the manual or observed engine ping suggests a benefit.
Practical fueling tips for the Civic
Apply these real-world tips to ensure you’re fueling correctly and optimizing performance and efficiency.
- Check your owner’s manual for the exact octane recommendation for your trim; for the 2024 Civic, 87 octane is sufficient for daily driving across most trims.
- Refuel at reputable brands to ensure consistent detergent additives and engine cleanliness; while not required by Honda, higher-tier fuels can help keep injectors and valves cleaner over time.
- If you notice knocking or pinging on regular gas, try a higher-octane fuel (89–91 octane) to see if the issue resolves. If it persists, have the vehicle inspected.
- Most driving scenarios—city commuting, highway cruising, and ordinary trips—do not require premium fuel; reserve higher-octane fuel for specific conditions or manufacturer guidance.
These tips help you apply the octane guidance in daily life and avoid unnecessary fuel costs while maintaining engine health.
Summary
For the 2024 Honda Civic, regular unleaded gasoline with an octane rating of 87 or higher is the standard recommendation. Higher-octane fuels are optional and may offer marginal benefits under certain conditions, but they are not required for typical daily driving. In the United States, most gasoline is E10 (up to 10% ethanol); use fuels that match the ethanol content recommended by your manual. Always consult your owner’s manual for the exact requirements of your trim and driving conditions. When in doubt, start with 87 octane and only move to higher octane if you notice pinging or a marked improvement in performance, then continue to monitor fuel economy and cost.
