Ford F150 King Ranch Pickup V8 Vs. V6 EcoBoost Fuel Economy 

Clearly, just a little more speed leads to a lot more fuel burn. I finally learned this lesson and now I limit my highway speed to 70 and my avg fuel economy has increased by 2 mpg. It definitely pays to take your time and use cruise control. Good video!

Interstering comparison. Thanks for your time vested in this video. Much appreciated.

Great comparison, thanks 👍

Really cool comparison. Did you actually calculate how much fuel was burned to calculate the exact average mpg? BTW, at 21 mpg vs. 23 mpg, at $6.00 per gallon (I live in California), that is $.02 per mile difference. If you drive 15,000 miles per year, that’s a difference of about $372 in a year, or $31 a month. If your gas is $4.00 per gallon, it is $.016 per mile difference, or $248 a year, or $20 per month. You are talking about $65k to $75k trucks. For a difference of $250-$372 a year in fuel costs, get the engine you want. For me, I am old school and love the sound of the 5.0.

Recent 1,893 mile trip in my 2016 5.0, 2wd, 3.31 rear end. I now have a little over 96,000 mi on it. 21.4 mpg. Best truck I have ever owned and at 69 years old I have had a couple. Eco boost not my cup of tea.

good work on the video and info!

I have a 2014 F150 XLT extra cab four wheel drive with the 5.0 and six speed auto. On a 500 mile trip with mixed driving, I get about 19-22 mpg. I love that Coyote, and, I never have to deal with turbos. I like a simpler truck. I also have a deluxe Leer fiberglass topper that adds at least two hundred pounds to the truck, along with the side steps shown in the video. For the differenc, I will take the 5 liter any day of the week.

I had a 1980 Honda CM400 motorcycle two cylinder engine that loved to cruise at 7000 rpm and would do around 55mpg or more if I kept it like that (which translated to around 65 mph on the highway). One time I decided to go a little faster while riding to a town 90 miles away. After going 45 miles or so I ran out of gas, and had to use the reserve and limp back to the only gas station there was in between which I had just passed 15 miles behind. So yeah speed kills MPG, lesson learned. By the way both are world class trucks and it's your preference but I do love my 2013 F-150 3.5L Ecoboost. On a side note this video had amazing potential if it wasn't for the bad camera movement in the middle of it. Cheers and thanks!

Can you do this test again with the new 2.7? Or maybe two identical trucks but with different gear ratios? Like 3.55 vs 3.73?

My mpg readout in my 2011 is a little conservative. 3.7L v6. Last tank the truck said 19 mpg average but calculated at the pump I got 20.

Great and interesting video. I have tow mirrors on my F150 and love them but am aware they cost me mpg's. Thanks for testing with the mirrors folded in. Good info. My thought is if tow mirrors cost about 1/2 mpg that's not bad. Regular mirrors still create drag. I'd like to know how much difference non-towing mirrors create. Maybe a 1/4 mpg???

I see you are in FL. if you do 50mph on I-95, you're prone to cause a collision or be in the collision. Overall interesting test.

it would be interesting to test aerodynamic mirror fairings - a nice pointy nose cone might make those flat-faced mirrors slip through the wind better

Good stuff

Had a 2015 4x w/ 2.7 , was getting 16.7 according to the dash.

Ugh, Costco is such a hassle trying to fill up that it's not worth the savings. They really need to expand their fueling stations across the country to allow for about twice as many pumps.

I've got a 2020 F-150 EcoBoost. It's not my first rodeo with a turbocharged vehicle, but just like the others I have a hard time keeping it out of boost. I get about the same economy as with my V8 naturally aspirated Nissan Titan 5.6 liter... which isn't super good because I was not good about keeping my foot out of that either.

I have a 2016 with a 3.5 eco. I might have gotten the kind of mpg going downhill with the wind at my back. The best I've gotten is 22 mpg and thats what its rated at.

So guys if i buy an 2006 5.0 v8 really get mix 10l / 100km? For real?

What would the fuel economy be if you drive side by side?

it looks like there was a difference in altitude between the ends of the trip. This test really needs to be done both ways in each configuration.

Cool comparison but most people I know that drive the eco-boost report average mileages much more similar to the V8 due to spirited and round town driving. What it boils down to is the turbo motor is either Eco or boost which consumes way more gas. I'll take the V8 sound and engine longevity over the V6 turbo any day. JMO

So what is the total miles driven to gallons of fuel used? We all know you can’t trust the dash readout to be very accurate. My 2016 3.5 Eco was about 3 mpg off (actual MPG was lower) of the dash reading.

So that extra speed is EXPENSIVE! It would be interesting to see how they do while towing.

And what was your average speed throughout the test?

I’ve had a 2017 ecoboost lariat sport FX4 since new. My truck has NEVER averaged over 20 mpg. Driving around town and casual highway driving I fill up my tanks with the onboard MPG average around 13-15 mpg. I’m a Ford fan, but these Ecoboost motors are deceptively rated.

V8 had a 3.31 rear end and the V6 had a 3.55. Would have been interesting to see which gear they were in during the test. V6 also had a pano roof.

Seemed concerned about wieght difference with the extra step for the bed but never mentioned wieght difference of engines?

Those trip computers can be way off on vehicles, their just an estimate. Need to take a few short trips and calculate actual mpg.

What was overall average of each?

My V-8 F-150 gets better mileage than my V-6 twin turbo explorer. Also. I get better mileage in Sport mode than economy. I have a theory on that.

The 32mpg was downhill?!

I get 19 to 22 n sometimes a bit over

Driving unloaded skews the results. Put the eco under load, and the fuel economy drops fast. I have the 3.5 with a 3.73 rear end, and I'm lucky if I see 10 mpg pulling a 20ft bass boat.

ugh, you can consider all of this fuel wasted, FOLLOWING truck, will show better fuel milege over the front one. Because rear truck has less air to go through, I can get my 04 F150 get 9.8L/100k if I follow transport truck. You never mentioned what gearing truck have. And using Costco gas......seriously? I am surprised that stuff even ignites

I don’t buy truck for fuel efficiency I buy them to be able to carry and pull things that I want but the most important thing is longevity and no problems but just changing oil and oil filter. The 3.5 is a fantastic motor it has more torque than the V 8 it is a great motor to toe with but due to the chains on the phasers and stuff like that stretching turbo issues also the tube that feeds oil to the turbo has a screen that clogs up due to the Blow by on the Pistons and dirtying up the oil causing all kinds of issues I just don’t want to deal with that. A engine like that also has a high-pressure fuel pump another issue it’s basically a small Diesel engine. But I know a lot of guys that love the 3.5 so to each his own

Doesn’t matter about fuel economy, they both have Ford’s garbage ten speed transmission. Buy at your own peril.

Admit it, you guys are Ford dealers, and you're just doing a soft sell.

False the turbo is engaged the waste gate is open not closed
