I only have about 3k miles total, but I was actually wondering the same thing. I fill about 17-18 gallons, but that is before the light comes on. One time I waited until the light was on, and it was still below 20 gallons, roughly 19 from what I recall.
Sounds like a pretty big reserve.
I also find that most pumps stop early and often during filling as well. I sometimes have to hold the pump handle halfway to fill more slowly. And that is NOT to top off. Anyone else experience this?
I fuel up about the same 18 - 19. I think I read that mentioned the LX has a decent size reserve in the tank... ?

I tapped into the reserve a couple times and I managed 21 gals, roughly same computed mileage per tank though. IMO reserve is bigger than it should be but hey at least I know its there.
