The 2018 Honda Accord requires 0W-20 synthetic motor oil for both engines offered that year—the 1.5-liter turbo and the 2.0-liter turbo.
In this article, we break down the recommended oil grade, standards, and practical maintenance notes for this model year to help owners keep their engines running smoothly.
Oil type and specifications
Key standards and grade to follow when selecting oil for the 2018 Accord.
- Viscosity: 0W-20
- Oil type: Full synthetic (Honda recommends synthetic motor oil)
- Certification/standards: API SN (or SP) and ILSAC GF-5 (or newer)
- Compatibility note: Do not substitute with non-recommended grades unless directed by the owner’s manual or dealer
The list above highlights the official specs for this model year; always verify with the owner's manual or a Honda service advisor if you’re unsure.
Why 0W-20 and what it means
Honda specifies 0W-20 for its modern engines to optimize fuel economy, cold-start performance, and emissions control. The thin viscosity helps the engine reach operating temperature faster and reduces friction during startup, which is especially important for turbocharged engines used in the 2018 Accord.
Standards and compatibility
Oil that meets API SN/SP and ILSAC GF-5 (or newer) is compatible with the Accord’s emissions systems and warranty requirements. When shopping, look for labels that confirm these standards and, if possible, choose a high-quality synthetic oil that is branded as meeting Honda recommendations.
Engine variants and oil capacity
Oil capacity varies slightly by engine; here are the approximate figures for the 2018 Accord.
- 1.5L turbocharged engine: About 4.4 quarts (with filter)
- 2.0L turbocharged engine: About 4.5 quarts (with filter)
When topping up or changing the oil, use the correct amount for your specific engine and always recheck the level with the dipstick after a fill.
Maintenance and change intervals
Practical guidance to help ensure you stay on track with oil maintenance.
- Recommended oil: 0W-20 synthetic that meets API SN/SP and ILSAC GF-5 or newer
- Change interval: Typical normal-condition interval is around 7,500 miles (12,000 km); more frequent changes may be advised under severe driving conditions
- Oil filter: Use a reputable filter and proper torque when reinstalling
Sticking to the recommended oil grade and regular changes supports engine performance, fuel efficiency, and longevity.
Summary
In short, the 2018 Honda Accord takes 0W-20 synthetic oil, with about 4.4–4.5 quarts required depending on the engine. The oil should meet API SN/SP and ILSAC GF-5 or newer standards. Always consult the owner’s manual for the exact specification and interval for your specific vehicle.
