do you have to change the oil on the all battery power Leaf.
According the the Service and Maintenance record leaked online (http://nissan-leaf.net/wp-content/uploads/2010/11/773326-2011-Nissan-Leaf-SMG.pdf),
The only maintenance required for the first 119,999 miles of the car is tire rotations, brake fluid changes, suspension inspections, and a battery life report download every 15,000 miles. At 120,000 miles, the coolant gets changed. I suspect the battery may need to be changed before 120,000 miles, but that is based on the battery life report, not miles or age. No oil changes, tune-ups, or belts to worry about.
There is no gas motor in a Leaf. There might be a need to change fluid in a transmission or differential, but not sure.
