OK, I bought a 2014 Jetta Wagon earlier this year and drove it back red-eye from CA to MN. I was just past Salt Lake City with an empty tank, thinking, I'll stop at the next exit, maybe they have a better place to eat there. It was about 10:00 PM. Well, that was an extremely bad decision. The next 3-4 exits kept saying "No Services." I was to the point of no return - going back would have been more miles than what I hoped was the next fuel stop. I was fully expecting to have to flag down a trucker, get a ride, and thumb it back. Was not looking forward to that, it was COLD and I had only a light jacket. The last 10-15 miles I slowed down to 40 mph in the unlikely hope I'd make it. Well, I did make it, fuel gauge way past E, to an exit with diesel. I filled up and the pump read 15.3 gallons.
Got thinking about it and looked at the owners manual. It says, fuel capacity, INCLUDING a 1 gallon reserve, is 14.5 gallons. So how the heck I put in 15.3 gallons I don't know. Never so happy to pump fuel as that night! Never checked, but if that wasn't a 700 mile tank, then one is not possible in a 14 JSW!
