Search isn't working, so forgive me if this has been asked before. I keep seeing people posting very high gas mileage (mpg) but I never get anywhere close to those numbers on my unmodified 2017 Springfield. I think I have seen above 41 mpg once, but most of the time it is between 35-37. Could it be it the way I ride or my maybe shifting? Is it that I am on slower roads and have to shift more than open highways? Just curious.
