467.2miles on one tank at 25.09MPG's
I'm back from the wedding in Minnesota and boy was it a blast(The driving that is). Managed to hit my highest tank to date at 467.2miles and 25.09MPG's, that's 87.2miles farther than this baby should be able to go and I still had 1.4 gallons to left. I would say that covering over those tow hook and fog lamp holes is well worth the effort. I noticed an immediate reduction in wind noise and enjoyed watching the MPG's hit 50+ headed down hills.
Here's one leg of the trip from a rest stop to the south end of Minneapolis. The scan gauge in the end was reading a few % high so compensating for that it should read about 27.55MPG's.
