Default An idea

Anyone tried the old skool method? Install a vacuum gauge and see just where the sweet spot is on YOUR motor? All motors are just a little different. Every car I have ever owned has gotten a vacuum gauge installed. Oly

edit If you run a 4100 carb you can use the vac gauge to set where the secondary's dump. Note the vacuum at which the secondaries open. Compress or stretch the spring to change when it dumps.

Maybe have to give that a try. When My 2013 King Ranch gets 16 mpg, I feel really lucky.

  • 2018 Lariat SuperCrew 'Sport' 4X4
  • 5.0 V8.
  • 3.55 rear gear ratio.
  • 9,800 miles on odometer.
  • Transmission Mode set to: Normal
  • Michigan winter gas blend (probably yields worse mpg than summer blend in summer conditions?)
  • No appreciable 'wind' in any direction....

Gassed up at fuel station right next to 'on-ramp' of highway. Entered highway under light/moderate acceleration. Put F150 on 'cruise'... speed set to 70 mph. Drove 60 miles down highway. Pulled off highway and right into another gas station. Filled up tank.

Computer MPG read: 20.9 mpg
Hand Calculation was: 20.03 mpg

Fairly close... computer was within 1 mpg difference.

Not sure the EPA sticker of 22 mpg highway is attainable in real world driving. Maybe with Summer Gas blend???

Under everyday driving conditions with 75% rural 55 mph roads... some highway and some city... I generally average low 17 mpg on computer.

Well done Joe. Try 65 or so next time.

Thank you D-D-in-KY. I will try that once and see what the difference in mph yields. I bet the results will be very interesting.
