I'm a new owner. I waited until the last marker is dim, then I filled up and it took in 14.1 gal before the gas trigger popped. I did this twice and both occasions, it took 14.1 gal to fill up. I checked the manual and other online resources that the fuel tank capacity is 13.2. That specification seems to be off. Any other owners having similar fill up experience?

 

I think they have about a gallon of "Reserve" not on the gauge
