The 2027 Odyssey does not use a fixed-interval maintenance calendar. Instead, Honda's Maintenance Minder monitors your engine oil life and driving conditions continuously, then surfaces one of two main codes and up to four sub-codes when a specific service is needed. Here is what each code means.

Main Code A, Engine Oil Replacement
The Minder triggers Code A when it calculates your oil has reached a point where replacement is needed based on actual driving conditions. No fixed mileage applies. When the display reads "Service Due Soon" at 15% oil life, plan to schedule promptly. At 5% ("Service Due Now") you should book immediately. At 0% ("Service Past Due") the service is overdue.
