The 2021 Honda Accord uses different oil amounts depending on the engine. In practical terms, the 1.5-liter turbo needs about 4.4 quarts of oil, while the 2.0-liter turbo requires roughly 5.4 to 5.7 quarts, with the oil filter included. The recommended oil for both engines is 0W-20 full synthetic.
Oil capacity by engine variant
To avoid underfilling or overfilling, identify which engine your Accord has and use the figure below. The capacities listed refer to oil with the filter in place.
- 1.5-liter turbocharged inline-4: approximately 4.4 quarts (4.2 liters) with filter.
- 2.0-liter turbocharged inline-4: approximately 5.4–5.7 quarts (5.1–5.4 liters) with filter.
Note: These figures are typical for the 2021 model year and can vary slightly by production batch or regional specification. Always verify with your owner’s manual or the under-hood sticker for your exact figure.
Recommended oil type and change intervals
Choosing the right oil grade and changing it on schedule helps protect the turbocharged engines. Here is the guidance most applicable to the 2021 Accord.
- Oil grade and viscosity: Use 0W-20 full synthetic engine oil (Honda Genuine or equivalent). Some local markets may have alternate acceptable grades; confirm with your manual or dealer.
- Oil change intervals: With synthetic oil and normal driving, the Maintenance Minder typically recommends an oil change every 7,500 miles (12,000 kilometers). In severe conditions (extreme temperatures, heavy city driving, towing), shorter intervals around 3,750–5,000 miles (6,000–8,000 kilometers) may apply. The onboard system will alert you when service is due.
Always consult the owner’s manual and your dealership for the exact requirements for your vehicle, as specifications can vary by market and production run.
Summary: For the 2021 Honda Accord, oil capacity depends on the engine: about 4.4 quarts for the 1.5L and about 5.4–5.7 quarts for the 2.0L, with a filter. Use 0W-20 synthetic oil and follow the Maintenance Minder for change intervals. Verify exact figures in your manual or on the under-hood label.
