Put a bottle of Techron complete fuel system cleaner into the Sentra that has 186K miles on it.
Before the treatment the info center said I was averaging 35.4 MPG.
After I ran the treated tank out and refilled I reset the info center.
Now after several fill ups and no change in driving habits it says 37.1 MPG.
I'm really surprised by this.
