Initial Impression: Truck seems a little more "heavy" and slower to accelerate, but not by much. I could definitely tell something was different in the truck, but not a bad thing. The city mileage sucked around 10mpg, but the highway mileage was around 17-18 according the scangauge when I was going around 60mph with minimal throttle pressure. I paid $1.75 a gallon for it, which was about 27 cents cheaper than regular. I'll keep yall posted on my impressions of it. I've got the Scangauge so I can gauge the mileage in realtime driving conditions..This morning on my rushhour commute to work I averaged 12.9mpg with the E-85. I didn't get to floor it completely, but it did feel a tad sluggish, but that could be in my mind. I'll test it out more this afternoon during lunch and on the way home tonight when there is no traffic. I'm not expecting to come out ahead on the $$ side of it, because I know right now it's not cheap enough to be a value, but I figured what the heck-I'll try it out. And the brochure on the pump had Nissan Titan (May '05 - Current) as being FFV compatible...I think it's a little misleading though, because I don't think EVERY May '05-Current Titan is FFV compatible, only if you had the FFV package. Do they all come with the FFV package now?
