How many MPG does the 2017 Nissan NV 3500 HD SL get?

We have owned our NV 3500 HD SL for 3 months. We have driven it just over 2000 miles. When we calculate MPG based on miles driven and how many actual gallons of premium gasoline were put in the tank.....

2017 Nissan NV 3500 HD SL gets an average of 11 MPG.

Next time, we will try putting in regular unleaded and see if it makes a difference....
