BSJ... It isn't much different, and my 14 is still breaking in. I actually got better mileage on my first 2 tanks on the 14 (about 50) than the mileage on the first 2 tanks on the 13 ( about 48) But my mileage got better and better on the 13 as it broke in, to the point where I was getting 54-55 mpg. I'm at 50 on the 14 with 641 miles on it, and suspect the mileage will also go up on it as the motor breaks in and frees up. At approx 2000 miles on the motor, I will have a good idea of what kind of mileage to expect from then on.
