1986F150Six Posted September 24, 2019 Share Posted September 24, 2019 Having just returned from the 2019 Garagemahal Truck Show, I need to update this data. One consideration for this year's data is that I had a passenger. Also, part of this year's aerodynamic modification [card board tube grill cover] had to be removed after the show, before the return drive, due to water damage caused by the heavy rain. 2014 55-62 mph with no aerodynamic modifications = 21.93 mpg [highest tank = 23.26 mpg] 2015 55-62 mph with aerodynamic modifications = 24.13 mpg [highest tank = 25.72 mpg] 2016 55-70 mph [weighted towards 65-70] with aerodynamic modifications = 22.05 mpg [highest tank = 23.46 mpg] 2017 Missing data due to having driven another vehicle. 2018 65-75 mph [closer to 75] with no aerodynamic modifications] = 19.87 mpg [highest tank = 21.3 mpg] 2019 65-75 mph with aerodynamic modifications = 21.65 mpg [highest tank = 21.95 mpg] 2019 60-75 mph with partial [see explanation, above] aerodynamic modifications = 19.12 mpg [highest tank = 21.17 mpg] Link to comment Share on other sites More sharing options...
Gary Lewis Posted September 24, 2019 Share Posted September 24, 2019 David - What conclusions do you draw from that? And can you tell much difference for the MPG on the way here vs the return? Meaning with/without the aero mods? Link to comment Share on other sites More sharing options...

Also, there was more tank to tank variability without the grill deflector. Link to comment Share on other sites More sharing options...

I thought that was it. And the variability is probably due to either speed differences having a bigger impact or side/head winds doing it. Or both.

Gary Lewis Posted September 24, 2019 Share Posted September 24, 2019 Look at the 2014 vs. 2019 [with full aerodynamic package] data! Big speed difference. Standing still aero doesn't help at all. At Mach 1 it helps bunches. Link to comment Share on other sites More sharing options...
