What's the absolute maximum range of your Duster?

Your dad must have had some pixie dust fuel additive. I-25 is exactly where I do a lot of commuting.

I'm betting slowing down might up the mpg but I still don't see it going from 16.5 to 26 by dropping from 85-90 to 70 mph

85-90 ? You are about topped out, huh? LOL :poke: Actually, his Valiant Signet did 112 top end on I-25 (according to the speedometer). Who knows by radar..... I think he averaged about 70 mph traveling to work on that interstate.
