In practice, Honda’s 1.5 L turbo engine used in many Accords (primarily the 2018–2024 models) is listed with a capacity of roughly 3.7 quarts (3.5 liters) when performing a full oil change with a new filter. The recommended oil grade is 0W-20 synthetic. Exact capacity can vary slightly by model year or engine variant, so consult your owner’s manual or the official service data for your specific vehicle.
