I just did a trip to Zion(Utah) this past weekend running on E85 and mostly driving 80mph and averaged 17.5mpg. I also did a couple spirited runs to 135mph when traffic wasn't around. I didn't see a single decent car on the road the entire trip until I was within 2 miles of my house(coming back). I lined up with a newer Porsche Carrera with the typical "I'm better than you and will prove it" driver and I owned his **** once the light turned green. I let off after I put two car lenghts on him..........when he finally caught up I yelled "you should've bought the turbo". He wasn't too happy. LMFAO
