The 2018 Honda CR-V runs on regular unleaded gasoline with an octane rating of 87 AKI or higher. This article breaks down the exact fuel type, octane requirements, and ethanol compatibility to help you fuel up correctly.
Gasoline type and octane requirements
Key details you need to know about the CR-V’s fuel type and octane requirements are explained here.
- Regular unleaded gasoline with an octane rating of 87 AKI (often labeled 87) or higher. Premium fuel (91–93 AKI) is not required for the 2018 CR-V; using higher-octane fuel is optional and typically unnecessary for everyday driving.
- In the United States and many other markets, 87 octane regular gasoline is approved for all CR-V trims equipped with the 1.5L turbo engine.
Bottom line: your CR-V should be fueled with regular 87-octane gas or higher; there is no requirement for premium fuel in normal operation.
Ethanol content and fuel compatibility
Next, ethanol blends and what fuel additives are compatible with the CR-V.
- Gasoline containing up to 10% ethanol (E10) is acceptable for the 2018 CR-V.
- Avoid using gasoline with higher ethanol content such as E15 or E85 unless your owner's manual or dealer specifies otherwise, as this can affect fuel-system components and warranty terms in some regions.
To stay safe, confirm the fuel type and ethanol compatibility in your vehicle’s owner’s manual and consider regional guidance if you’re buying outside the U.S.
Practical fueling tips
Always fill with reputable brands to avoid fuel-line issues, and avoid frequently switching fuel grades. If you’re unsure, consult your Honda dealer or the owner’s manual for the exact specification for your trim and market.
Summary
The 2018 Honda CR-V accepts regular unleaded gasoline with an octane rating of 87 AKI or higher, and it is compatible with up to 10% ethanol (E10). Premium fuels are not required, and avoid higher-ethanol blends beyond E10 unless your manual indicates otherwise. Always check the owner’s manual for your specific market and trim.
