Need Help Deciding What Motor....

[Vulnox]

I definitely say 2.7L. It's faster than the 5.0L, which isn't super helpful but doesn't hurt either. It is built like a diesel in terms of block material and that, while some mention they worry about longevity, the 2.7L has been bulletproof while tons of 5.0 owners have complained of oil burning, ticking, all kinds of stuff (on last gen at least, too early to know how much of that is worked out, hopefully all). All the engines are extremely complex, adding a couple turbos doesn't alter that equation too much.

Fuel mileage is great, but I think both the 5.0 and 2.7L get great average fuel mileage. Biggest reason I would pick 5.0 over 2.7L is if you are lifting it and putting on larger tires, or plan to tow 5,000+lbs semi-often. The 5.0L does a lot better on fuel mileage while towing, while the 2.7L tows easier. But the difference isn't significant enough to overcome that fuel mileage difference IMO.

Really, I think the 2.7L and 5.0L represent the best all-around engines, so either is a good choice. No doubt the 5.0L sounds better though. I would just say drive both and go from there. I have had 2.7L my past two trucks, and have a PowerBoost on order. I drove my dad's 2016 5.0L and it's fine, but it's a coupe engine at heart and you need to rev it high to get the quoted power numbers, it just never felt as easy to engage as the 2.7L. Your experience may differ (while I have driven the 2.7L and 5.0L with a 6 speed, I haven't driven the 5.0L w/ 10 speed).

My vote is for the more modern 2.7. They are proven to be reliable.

I did the math. It is a $3800 upgrade for the powerstroke over the 2.7l. If you assume all highway miles, the 2.7L getting 24mpg and the powerstroke getting 30mpg, and 30,000 miles a year (which most people will never hit), then it would take 7.5 years for the diesel to pay for itself. 15 years at 15,000 miles, so not really worth it unless you do a lot of Highway mileage.

Also OP only has the option for the 2.7L and the 5.0L so there is that...

Edit: this is also assuming a $0.26 per gallon cost difference which is the difference near me

The 3.0 was a $3000 option with a $500 rebate from Ford. Plus there is a 100,000 mile warranty on the engine.

This guy is hardly driving any city miles and has not seen 24 mpg for the first time https://www.fuelly.com/car/ford/f-150/2021/dehill35/1066699 Lots of ECO and some 5.0 folks like to tell fish stories about what kind of mpg theyre getting. One 2.7 guy on there lists 45 mpg on one tank full. Thats incredible.

Between 20 - 30 mpg is where you can land all day long with a 3.0 if you dont tow. Maintenance costs are overblown and I just saw diesel fuel for 30 cents more than crappy 87 octane. The window sticker EPA ratings by the way are with 91 octane for fuel.

Bottom line is that diesels have been the mainstay in Europe for decades because fuel is so much more costly over there and they can get more bang for the franc. Diesel engines last longer and will blow past 200,000.

Again you miss the point. OP only has the option for 2.7L and 5.0L at his local dealers. This wasn’t a “What’s the best engine in your opinion” post. This was a, “Which out of these two engines should I get” post.

As far as price, I’m going based on the build and price tool on Fords website. On an XLT it is $5000 for the Diesel, $1200 for the 2.7L, and $2000 for the 5.0L. Considering the EPA highway number for the 2.7L is 24, which is what I used and 22 for the 5.0L, the price difference for my comparison is $3800.

As far as MPG, don’t use Fuelly as an argument against the 2.7L when there are no 3.0L diesels on there for ‘21. If we look at 2019, there were only 2 diesels listed on Fuelly in 2020, the peak of the chart is at 20mpg for the diesel (9 users) or 22 if you look under V6 diesel and 18-20 for the 2.7L (73 users) https://www.fuelly.com/car/ford/f-150/2019?engineconfig_id=&bodytype_id=&submodel_id=

Look I’ve driven the diesel for work several times and it’s a great engine. But the OP only has the option for 2 engines neither of which is the diesel. You used personal/ hearsay evidence to prove your point which I have listed actual data points which disproves what you said, not to say your lying about your experiences

I have listed REAL 2021 data points.

2.7L:
Based on data from 6 vehicles, 66 fuel-ups and 20,978 miles of driving, the 2021 Ford F-150 gets a combined Avg MPG of 17.18 with a 0.47 MPG margin of error.
5.0L:
Based on data from 7 vehicles, 37 fuel-ups and 11,360 miles of driving, the 2021 Ford F-150 gets a combined Avg MPG of 16.99 with a 1.11 MPG margin of error.

Completely missed the blue box on my phone lol. Didn’t realize they actually listed the averages. Will see where I land with my 5.0L when I fill up this weekend.

Looks like for 2019:
2.7L: 988,851 miles of driving, the 2019 Ford F-150 gets a combined Avg MPG of 18.45 with a 0.12 MPG margin of error.

5.0L: 367,289 miles of driving, the 2019 Ford F-150 gets a combined Avg MPG of 16.42 with a 0.18 MPG margin of error.

3.0L Diesel: 108,744 miles of driving, the 2019 Ford F-150 gets a combined Avg MPG of 19.04 with a 0.44 MPG margin of error.

His company just bought him a 6.7 Power Stroke, so he is already seeing the benefits of a diesel over his personal gasoline 7.3 Tremor. 3 motors were actually mentioned, but he stated that he is unsure about a gas F150.

Obviously this person enjoys having power owning a 7.3 and my point was to go outside of the local area within reason and try to find the more powerful 3,0 F50. So, to reply to his question, my answer would be neither of those 2 engines. The 5.0 has new cylinder deactivation technology that Chevy had problems with. The 2,7 has 2 turbos that generate the power.

The lack of 3.0s on Fuelly does not change the fact that 24 mpg is a dream with a 2.7.

 

[Bryan Simon]

The 5.0 has new cylinder deactivation technology that Chevy had problems with.

no absolutely positive about this, but I believe GM went with a ”random” deactivation that shut various cylinders off Willy Nilly at the whim of the PCM.
I believe the blue oval went with a much less complicated “Cut these four out and don’t over think it” route.
im not gonna advocate either one and I was a bit dismayed when I found out my 5.0 would have this “unwanted feature”.
But, it does seem to work as intended and I cannot feel it happen but can see it on the “fuel mileage meter” when it jumps up to 25-30 mpg.
I can feel all 8 come into play with a slight push on the accelerator. Feels like it just shifted half a gear.

 

[mnsunset]

Traded my 3.5 ecoboost and ordered the 21 with the 5.0. Towed a lot with the ecoboost and the thing was a beast. BUT I had a lot of issues. Throttle Body (hello limp mode), exhaust manifold warped, Coil pack premature failure, and finally turbos going out. I will admit some of these issues related to towing and heat. But that was what it was advertised for. When the engine worked, I really liked it. But I wanted to go back to basics of the 5.0. Love it. Will likely not go back. Plus the real sound is great. VS pumped in fake noise. I kinda miss the little turbo noise once in awhile.

 

[3DogKnight]

Hey Everyone! I am looking into purchasing a 2020 or 2021 F150 in the coming days. I already have a 2020 F350 Tremor with the 7.3 and I love it. However my company just purchased me a new F250 with a 6.7. I really don't need my F350 anymore. I've decided to trade in my F350 and buy a new F150. I seen that my local dealership has some pretty good deals on F150's but they have the 2.7 and 5.0 motors. It's been a while since I've owned an F150 and need some help figuring out what Motor to go with? I know everyone likes the 3.5 however the trucks I'm looking at only have these 2 particular motors available. If you had to choose from the 2 motors I stated which do you think I would be better off with and why? Thanks in advance for the help!

2021 5.0 has cylinder deactivation and an oil pump belt vs chain on older 5.0's. Just my two cents on this.

I have the 5.0 with a 6 speed and 3.73 gears. Good motor, no problems, but I don't like it. The lack of low end power bothers me. I feel like I have to rev it above 3k to get it to perform. Maybe the 10 speed fixed this.

 

[NH_Leadfoot]

I have the 5.0L with 3.73 rear end and I love it coupled with the 10spd. If I go easy with it I'm averaging 20mpg per tank. The hard part... is going easy with it.
