Hello, I would like to ask you guys your experiences with the car miles range just after a refill. So, the Seltos has roughly 13 gallons in the tank. My avg mpg is 25 (mostly city drive) and it is as described in the car specs. However I noticed that when I refill the tank, the total miles range goes to around 400 miles (that means an mpg above 30) while in reality I am only getting about 250 miles per tank. How is that? And what's your experience? Thanks
