The 2018 Honda Accord generally uses 0W-20 full synthetic engine oil for both the 1.5-liter turbo and the 2.0-liter turbo engines.
In 2018, Honda offered two turbocharged powertrains in the Accord. Both share the same oil specification, and Honda’s guidance emphasizes using a high-quality synthetic oil that meets certain industry standards. This article outlines the exact oil type, standards, and practical notes for owners aiming to keep their Accord running smoothly.
Oil type and specifications
All 2018 Accord models with the two turbocharged engines are designed to run on the same oil grade. The key is to choose a 0W-20 full synthetic oil that meets established industry standards.
Oil standards and what to look for
When shopping for oil, verify that the product specifies 0W-20 and carries the appropriate certifications. The oil should meet or exceed API SN or a newer specification and ILSAC GF-5 (or newer). Honda’s own Genuine Motor Oil is recommended, but any reputable fully synthetic 0W-20 that meets API SN/ILSAC GF-5 (or newer) is acceptable.
- 0W-20 full synthetic engine oil
- API SN or newer specification
- ILSAC GF-5 or newer specification
- Honda Genuine Motor Oil preferred, or a high-quality equivalent that meets the above specs
Choosing an oil that adheres to these standards helps ensure proper lubrication, fuel efficiency, and engine protection across driving conditions.
Practical notes for owners
Engine oil changes in the 2018 Accord are guided by Honda’s maintenance minder system. This means intervals can vary based on driving conditions and usage. Always refer to the owner’s manual or onboard maintenance minder for the recommended service timing, and use oil that clearly meets the 0W-20 and API/ILSAC specifications noted above.
Summary
For a 2018 Honda Accord, use 0W-20 full synthetic engine oil that meets API SN or newer and ILSAC GF-5 or newer. Honda Genuine Motor Oil is recommended, though any high-quality synthetic 0W-20 meeting these standards is acceptable. Follow the vehicle’s maintenance minder to determine oil-change intervals and ensure optimal engine performance across all driving conditions.
