How Long Will 2.7 Ecoboost Last: Maximum Mileage & RELIABILITY
How long will 2.7 Ecoboost last? This engine’s reliability compared to traditional V6 and V8 counterparts, and its endurance like previous models, considering modern technology and emissions systems, intrigues many. Seeking insights into its recent performance and a comparison with the established 3.5 EcoBoost? This article delves into these queries.
What’s the maximum mileage you can get on a 2.7 Ecoboost? With proper maintenance and timeous replacement of oil, spark plugs, filters, and transmission fluid there should be no reason why this engine cannot last up to 200k miles or more.
The 2.7 Ecoboost debuted in 2015, and a second generation launched in 2018. It’s featured in numerous Ford and Lincoln models. This high-tech, fuel-efficient engine is aimed for greener, potent performance matching NA V6 and V8s. Has Ford managed to achieve this?
Let’s find out what the owners have to say…

How Long Will 2.7 Ecoboost Last: Maximum Mileage
Below are a few real-world examples of the service, reliability, and issues they’ve experienced with the 2.7 mill.
User Experience
User Experience #1
I have a 2015 F150 2.7 Eco boost, and presently have 103,243 miles on it. I use, and have used, full synthetic oil, premium gas, and adding a Chevron Techron additive once a month. I’ve replaced the battery, and fuel pump. Otherwise only routine maintenance, I changed the plugs at 100,000, and found very little build up on the plugs. Oh yeah, one new set of tires, about to put another set on this month. I also changed the brake pads when I changed my plugs. Yes, I went 100,000 miles on the original brakes… any questions, please ask.

111,000 on the 17 now. Motorcraft oil and filter per monitor. Drivers side turbo under warranty. Rear brake pads at 40k. All factory otherwise, Even plugs. Still rocking the factory Michellins even. Best running truck around.

I’m now at 100K miles on truck (70k on engine). The 2.7 has been flawless. I’m getting better gas mileage now than I ever have before. I did drain and fill the tranny fluid at 90k and again at 95k miles. Still love this truck.

2.7 Ecoboost Reliability
The 2.7 Ecoboost has only enjoyed a short time on this planet and there aren’t many high-milers running around just yet. The general consensus, however, seems to be that there are no “common problems” on these lumps to be overly concerned about. For additional peace of mind, invest in this affordable Bluetooth OBDII Diagnostic scanner and clear CHECK ENGINE light device.
Reports vary on 2.7 Ecoboost reliability. Some faced turbo or engine issues under 100k miles, but these cases seem uncommon. Rare occurrences include blown head gaskets or cylinder head replacements under warranty. Doubts persist on its longevity reaching 200k miles, prompting consideration of the proven 3.5 or new 5.0L for high mileage or towing needs.
…the longevity and reliability of your truck boil down to thorough and meticulous preventative maintenance being carried out
At this stage of the 2.7 Ecoboost lifespan, most owners praise its stellar performance. The 2020 model is noted for being quieter and an improved experience compared to the 1st Gen. Mechanics emphasize the importance of thorough maintenance, quality lubricants, and top-tier fuel for maximizing truck longevity and reliability.
Known 2.7 Ecoboost Problems
With any new range of vehicle or engine, it usually comes with a caveat. That being so, there are almost always going to be little niggles and teething problems. This can usually be put down to improper assembly or premature parts failure.
At this stage there aren’t any known issues to report on, however, forums and discussion groups have reported a few of the following cases:
- Blown Turbo’s
- Blocked Catalytic Converters
- Blown head Gaskets
The 2.7s are proving reliable, praised by users. Even though most haven’t hit 200k miles in its 5+ years since 2015, they endure well. The 2nd Gen, more refined, includes port injection vital for turbocharged engines, preventing carbon buildup. Long live the 2.7!
What Is Better – The 2.7 Or 3.5 Ecoboost?
This question boils down to the age-old debate about displacement.
There’s no replacement for displacement…
Or, that’s how most large truck owners reasoned for many years. Recently though, we’re seeing large trucks being produced with smaller displacement engines. With gas prices constantly on the increase and manufacturers under constant pressure to develop safer greener vehicles, it appears that big displacement trucks are becoming a thing of the past.
So if you’re in the market for an F150 you basically have 3 options. The new 2.7 twin-turbo, the slightly older 3.5-liter V6 gasoline direct-injected and turbocharged engine, or the all-new 5.0-liter gasoline V8 engine, developed to compete directly with the GM 6.2L V8 engine and the new Chrysler 6.4L Hemi.
When it comes to daily driving and efficiency the 2.7 is the obvious choice. The 2.7L version is designed to deliver comparable power and torque of large displacement, naturally aspirated V6 and V8 engines but with less fuel consumption and emissions. It can even tow if required and does so very well.
The 3.5 is a more proven platform, having been introduced in the F150 in 2009. It’s proven to be reliable, robust, and durable with a proven track record. When it comes to towing the 3.5 is a freight train, so it comes down to what you’re looking for in a truck. The engine has good longevity if owners stick to the maintenance schedule and use only high-quality oil and lubricants. The average trouble-free mileage for the 3.5 EcoBoost engine is about 200k-250k miles, thereafter it’s down to the owner to keep it going.
Final thoughts
F-150 2.7 Eco Boost has been around for over 5 years with an updated Gen2 released in 2018. This is enough time to prove its worth. In many cases, it’s not the engine that becomes problematic, but rather the complex electrical systems and management aids being implemented in these vehicles, which makes them appear niggly.
