I always use the truck stop area to fill up. With a 90 gal tank, at 8.9-9 mpg, a 1/4 tank will allow me to go approximately 200 miles. So, when it gets to 1/2 tank, I start looking to fill up again.
The truck stops stations have large nozzles and can pump to fast. I will use the first click on the nozzle, and when it clicks off, I'll wait a few minutes and then hand feed it the rest of the way. Only problem with this is that sometimes you cannot judge when the tank is full and it will back-flow. I cuss, but I know that is as full as it is going to get. Most time I just stop pumping once it clicks. 10 or so gallons is not going to make that much of a difference for me when i fill at the half tank level.
