Some day, no time soon they'll figure out how to get a near 6,000 pound vehicle down the road at an effortless 130 mph, and return 25 mpg on regular fuel. The last 7-10 year expeditions do all right. Theirs going to come a time real soon that our cars and trucks are going to look and drive like George Jetsons foldable briefcase car. Enjoy your behemoths, and their 8-15 mpg while you can. I grew up during an era when you could buy 102 leaded octane gas. If you had a trick enough 11.5 to 1 compression car, you needed it. Ah the good old days! Compared to now they were that good. At least we could work on 90 percent of everything!

GM just redid the 5.3 and 6.2 and they now have V2 mode with completely variable displacement for 2019...crazy. they haven't released HP and Torque figures. i'd be disabling that AFM ASAP. I do enjoy driving the bohemith.

i have no skin in the game. i could give two ***** what people online think of me or my opinions. i would ABSOLUTELY admit it if something i bought was a dud.

that being said...... 3.5 EcoBoost is a hell of a motor!!!! I have beat on my latest harder than most will beat them in a lifetime. 60,000 HARD miles in two years!!!!! I have ONLY changed my oil. It is the strongest, most reliable motor i have ever owned. there are millions more just like me. i have several dozens friends and tradesman who do the same. most with well over 100,000 miles.

keep in mind, they sold 894,000 f150s last year alone!!!! this was double the closest competitor. the more of something there is, the more likely you will hear something negative.

no denial here, just real world first hand experience from someone who knows more than your average joe about vehicles.

if you are not buying a new expedition because of what you stated, you are doing yourself a major disservice.

only 60k? no vehicle should have problems at 60k for what they charge today!

I would not buy one, because you beat one and it did not fail. The are plenty of people who had timing chain problems. That kind of, out of warranty stuff, is a turn off. I would hope a new engine would be problem free, in its first two years. Ford only sold, so many, because of EB rebate on the F150. I had read many on this forum, unhappy about the EB, being only engine choice in the EXpy.

you are not doing the math right! in Jun 2016, ford had sold 1,000,000 ecoboost f150s!!! there are over 1.5 million 3.5 ecoboosts on the road!! the tiny number of complaints you have heard and read online dont amount to anything. literally nothing. there were much larger problems with the 4.6 and 5.4l with cam phasors, blowing spark plugs, breaking sparkplugs, etc. you know the only thing you will read about is the negative. that goes for anything. the people with issues are going to be much more vocal than the people who are satisfied. if you have found 1,000 examples of dissatisfied people, that is .06 percent of the number of engines on the road!!!! DO THE MATH!!!

edit; my numbers are way off. there is WAY mor than 1.5 million of them on the road. i didnt realize how many other vehicles had the 3.5 EB in them.

Ford had issues with 4.6l cracked plastic intakes and 5.4l ejecting plugs and ticking phasers. Many occurred, years later, out of warranty. Based on there track record, I have doubts the EB will be different. Look up 3.5l timing chain rattle/check engine light. My local junk yard had a turbo sitting on the counter. I asked about it, he said they get calls for them all the time. I think your over stating, with tiny number of complaints. How can you possibly know? The first batch have only been out of warranty a couple of years.

The 5.4L Triton is a very strong engine, 2 Valves were the best and less complicated before VCT. In 04 they got a bit more complex but still a good motor. It’s a strong running cast iron block V8. There are probably 10-15 times the number of modular V8s out there than ecoboosts, hence a lot more customers to complain. Timing parts are a relatively small piece of the puzzle on modern engines. I don’t know anyone who has actually had to do them on their 5.4L. The 3.5 has been prone to timing issues but that happens on mass produced engines. We are way off topic now so I’m going to crawl back into my cave :hidesbehindsofa:.

'97 5.4L Boosted. Run premium when severe duty (timber roads during hunting season and prep times or long distance) hauling to prevent detonation. Manufacturer's data and owner's manual recommends it. Just like putting ice in the aftercooler tank, only for severe use.
If I keep my foot out of it for everyday driving, '87 octane seems to work just fine :happy107:
