Just bought this from a private party and ran my first Full to Low Fuel warning tank of fuel. Fill up was 26 gallons. Spec capacity says 31 gallons. I would have thought that the Low Fuel warning would have gone off at 28-29 gallons. Is this what other owners have experienced? If typical I now know that I have a 100 miles range left on Low Fuel when running lightly loaded mostly highway miles.

For the record, I got 460.7 miles on that 26.2 gallons for an average fuel economy of 17.6 MPG. This was mostly highway, some city driving, unloaded (except for kids, dog). I'm happy with the MPG as our old '93 5.7L Suburban K1500 would get 13-14 MPG in the same conditions (fully tuned up, correct tire pressure, etc).

thanks...
