Gas and Flex-Fuel (E85) Nissan service schedule notes
For most Nissan gas engines (including flex-fuel E85-capable variants), the most frequent routine item is the oil and filter change, commonly based on both time and mileage. Depending on engine and usage, oil services are typically set around 6 to 12 months, with mileage targets varying widely across the range. If you do lots of short trips, towing, or stop-and-go driving, it is normal for the correct interval to be at the shorter end of the schedule. Flex-fuel operation can increase the importance of using the correct oil specification and sticking to the severe-service interval where listed.
