I have 285's and I get roughly 415 to a tank in my 04 Screw. Thats on the highway though. I just ordered and edge, i dont expect much to change so maybe I can get 416, thats my goal...lol

 

I Have An 07 With The V6. Decent Power For What I Need It For. Mpg Used To Be Fair At 16 To 19 Range. Then I Bought New Tires And Wheels.... Went From Stock Steel Rims 235/70/17 Hankook To Fx4 Rims And 10 Ply E Rated 305/65/18 Bfg All Terrains. Now I Average 12 To 13. Sux But Looks Great. Ill Deal.
