maybe it's your tuning!This is what drives me nuts. You're getting 16-17 going 70 with a 2wd truck. Your truck is lighter than my Ex, you have less parasitic drag with 2wd vs my 4wd, and you drive typically 10-15 MPH slower than I do. I have 285s as well....in 75-R18 flavor. 16-17 is my average, with both city and hwy factored in. When I'm doing strictly highway I get 18 usually, unless I drop my speed down to 75, and then I'm almost to 19. (these are all summer figures, of course) I just hate how inconsistent our mileages are. I realize there are a lot of variables, but it's crazy to see how wide a range we end up with.
i've been saying it for years that I'm going to get an sct and a custom tune for economy and logical egr delete ... maybe next year for my birffday lol
