17.4 MPH

[Wilbur]

I usually average 15.4, but I saw 19.2mpg on a short road trip once. All flat back roads with cruise control set at 59. I was actually really impressed because on my old SUV (Acura MDX) I never saw above 18.

I am a bit of a record keeper, having worked for Uncle Sam for 36 years. I have recorded every fill-up for 11 years. I keep a small calculator in the truck, and do a little arithmetic every time I visit the gas station. So I have 11 years of independently calculated mileage results. You can call me a liar if that's what you do for entertainment, sir, but I have the records to prove my case.

Ruger he saved you from your Gen1. There is no way a Gen 1 can get better mileage than a Gen 2. Mine does, hope he doesn’t go off the rails becuz I said that.

You’re arguing with physics. In addition to the EPA ratings and real world results. Which makes you wrong.

But hey, keep making a fool of yourself. You seem to be good at that.

You have an opinion. I have 11 years of gas mileage records which are (take note, please) "real world results."

I drive conservatively, as I have learned over the years that being in a hurry doesn't pay. You may get there 30 seconds sooner, but you're likely to endanger yourself, your vehicle, and many others on the road to do it. I don't. I'm easy on the gas pedal, and let off long before others when there is a red light ahead. Many, many times I keep rolling and don't come to a full stop, and that saves gas and brake pads. (I have 94,298 miles on the odometer and have lots of pad left on the original factory brake pads.) I have posted many times on this forum that the one and only one fuel saving device on a 3-ton, fire-breathing, 4X4 with aerodynamics not much better than a brick is a mature right foot, and I practice that.

I have nothing to prove to a man who would so arrogantly and publicly call another man a liar and a fool. I doubt that you'd do that in person. I don't know what you're trying to prove about yourself, sir, but thankfully I don't care.

I never called you anything. I simply questioned the plausibility of your claims, which are not only well above what these trucks typically average, but above the EPA rating as well.

You’ve proven in the past that you’re a Gen 1 fanboy who doesn’t understand the first thing about engine performance or efficiency, look at this nonsense:

For comparison:

On summer gas (winter gas has less energy) I get between 15.5 and 16.5 mpg with my 2011 6.2L SCAB in 2WD. This is absolutely unfailing. It doesn't matter whether the driving is predominantly city or highway. Surprisingly, speed doesn't matter either. What does matter is my right foot. Drive sanely and the big V8 will produce surprisingly good gas mileage.

You guys who waited for a GEN2 because you thought that a V6 with twin blowers would produce markedly better fuel economy forgot something important:
Physics. It takes a certain amount of energy to move a heavy, big body, high profile vehicle down the road. To do the same work requires the expenditure of the same amount of energy. That energy will come from the fuel consumed and from nowhere else. Miracles do not happen between fill-ups. Physics happens.

^^^"The 3.5L...benefits from having almost half as much displacement..."

LOL, that's pretty funny! Here are some corollaries:
- President O benefited from having almost half the IQ as President R.
- Twiggy benefited from having almost half the bust as Raquel Welch.
- The Japanese Zero benefited from having almost half the horsepower as the American P-51 Mustang.

Okay, I admit I'm poking fun and taking (very) modest liberties. However, there are some things in which raw size trumps everything. In this case, the argument is that the GEN2 engine which was shoehorned into the Raptor platform to satisfy EPA fleet mileage requirements is a categorically better installation than the GEN1 engine which was designed specifically for the Raptor platform. Another way to put the argument is that trading mechanical simplicity for mechanical complexity (two blowers) is a step up (even though it violates the Occam's Razor principal). That this is unlikely (though not impossible) should be obvious. The truth? It'll become obvious, too. It always does.

The fact that you claim the 6.2 was “designed specifically for the Raptor platform” says it all lol, that is comical. Keep trolling mister self righteous. And averaging “16MPG” in a Gen 1

Well then, I'm not really impressed with the results, ha ha.

OP has some significant mods, I believe that was his reference.

@Todd Turbo S, can you elaborate on the details of your mods?

 

[TwizzleStix]

Hmmm? From the thread title I expected some speed-related discussion, but it’s actually MPG talk. Oh well, I can set my tire size to get 20mpg if I really wanted to brag about something in this thread.

All good that the hurt-feelings folks from earlier Fords need to bash the newer technology. People did the same when the personal computer was released as well. Always attitude between the mac and pc users. Anyway, heavy boat anchors are essential if you have a heavy boat, so it’s all good.

I have a '19 and if I stay below 62 mph, I get anywhere from 19 to 21 mpg (mostly in the 20 range), get to 65 to 75 mph and it averages usually 18.5 to 19.5. 80+ and it's 17 to 18 under normal conditions. If is shows any boost when cruising it minimal other that going up hills.

On the other hand, just drove from Florida to New Mexico and got 15.5 to 16 at 80 mph in Texas and NM. Was bucking strong winds and increasing elevation. Was in boost almost constantly due to headwinds and rising elevation.

Also had a '13 SCrew with a 3.5 that performed similarly under similar conditions. '13 averaged about 1 mpg better across the board but mileage was also down some in cold and/or windy conditions.

'19 has just shy of 40,000 miles and is bone stock.

Just my experience.

I have Roush CAI, AMS boost tube, Wagner intercooler, Deaver Springs (OEM height), Ford Performance Cold Spark Plugs and Ford Performance rear diff cover. Not that it matters, but also Alcon BBK
