1986F150Six Posted August 29, 2019 Share Posted August 29, 2019 Back in September of 2016, a gas mileage comparison was made. Gary, with his 2015 F150 and I, with my 1986 F150 drove the same route. I followed Gary's lead. We began at Mr. Bass's gas station by filling the tanks as full as possible [each driver filled his own truck] with 100% gasoline [what Gary regularly uses] from the same pump. The loop was ~ 60 miles with varying speeds. At the completion of the test, tanks were again filled from the same pump. This is what Gary reported: This was posted on 9/16/16. Gary Lewis Posting Legend Thread Starter Join Date: Jul 2010 Location: Northeast, OK Posts: 32,866 Well, the 2016 Okie GTG has begun. David/1986F150Six got here about 2:00 and we ran a gas mileage test between his truck w/a 30 year old 300 4.9L six and my new 3.5L EB. We filled up at the same pump, and then he drove right behind me for a 63.9 mile route, after which we again filled up at the same pump. I babied mine as much as possible and got 19.95 MPG. That's the best my truck has ever gotten, and I was happy. But, David didn't know the road and he was trying to react to my moves and stay a fixed distance behind me, so he was working the throttle more than I was. AND HE STILL GOT BETTER MPG - 21.69. So much for new being better than old. On September 20, 2019, the test will be repeated, but this time, after Gary fills the tank for his truck and I fill my truck's tank, we will swap vehicles. Gary will still lead the way. The results will be posted. Link to comment Share on other sites More sharing options...

I don't believe so, Jonathan, but if I get the chance, I will once again attempt to enhance the aerodynamics??? Link to comment Share on other sites More sharing options...

1986F150Six Posted August 29, 2019 Author Share Posted August 29, 2019 Are you still desiring the smaller F100 style mirrors? If I had some, I would put them on for the drive to Skiatook and back. Link to comment Share on other sites More sharing options...
Rembrant Posted August 29, 2019 Share Posted August 29, 2019 If I had some, I would put them on for the drive to Skiatook and back. Do you mean the little Type-5 mirrors? Link to comment Share on other sites More sharing options...
1986F150Six Posted August 29, 2019 Author Share Posted August 29, 2019 If I had some, I would put them on for the drive to Skiatook and back. Do you mean the little Type-5 mirrors? Yes, Cory. This would simply be to lower wind resistance during the extended highway drive. Link to comment Share on other sites More sharing options...
Dorsai Posted August 29, 2019 Share Posted August 29, 2019 Yes, Cory. This would simply be to lower wind resistance during the extended highway drive. I believe my mirrors are type 5, but you wouldn't know it from my gas mileage numbers. Link to comment Share on other sites More sharing options...
