Ford eco boost

[Williy]

Back in the late 60's a guy I went to high school purchased a 1968 plymouth and all he did was piss and moan about its a piece of junk he was a ford man and pumped the hell outa the gas pedal and flooded it every time. I told him just push the pedal to the floor one time take foot off pedal turn key to start but he insisted to pump the gas pedal his wife had no trouble when I told her how to start it

Our 2003 Dodge diesel if I drive 55 mph I
can get between 25 & 30 mpg but driving
80 only get 18 or 19 depending on the wind

Once owner of a now traded 2001 F250 7.3l power stroke (170k over 13 years).
Some things I've learned along the way.
1- NEVER follow OEM oil change schedules. Why? they will get you out of warranty window but then you're on your own, right?

The owners manual has two oil change schedules: the regular one that everyone including the dealer follows, and the severe duty one. But when you read the fine print, severe duty sounds like most people's regular driving. Towing, yea not everyone does that, but stop and go traffic is pretty common. It's unusual for people to actually meet the regular schedule requirements.

Turbos by nature will coke up lube channel in the circuit. Have witnessed many 6.0l and 6.4l owners at work come in hot from a 20-70 mile daily commute and shut them right down. All turbos need at least 30 seconds to spool down and oil temps equalize a few degrees. (I do the same on the Kioti)
The only lubrication left for the turbine wheel is the residue in the turbo chamber and then heat soaks and eventually cokes up reducing volume. Change oil often, 3k to 4k, owner must determine each case. Allow turbine wheel to spool down.

A lot of modern turbo vehicles have water cooled turbos and coolant afterrun pumps. Turbo tractors might not have either of those.

2- Many have had great success of using a oil catch can to capture blow-by of the engine. This reduces oil contaminants.

At least in turbo cars some OEs have figured out how to make decent oil separators. The aftermarket will still sell you a catch can though.

5- Spark plugs- Change at 90k-100k or at least remove to inspect them.

Gas turbo cars can be hard on plugs. I replace them more often than that.

OTOH, with a gas turbo engine you can get a tune that will get you significantly more power for not much money. A lot of them are EPA and CARB approved even. My previous turbo car went 140k miles before I sold it, most of that with a tune and some bolt on parts.

I'd sorta expect any modem vehicle, regardless of quality, to have no real issues while under 100k miles.

And quality ones to go to 200k quite easily. I always intend to drive a car to 200k. Not impressed with "no issues" while under 100k honestly. That should be the bare minimum for the price tag

When I was much younger I had a Ford Pinto that was trouble free as well.

Recommend binge watching this channel as he only works on Fords and has years of experience on Eco-Boost and the famous 5.4l Triton engine issues.

Currently have the 5.4 Triton in a 2002 F150, 135K mileage. Plastic intake cracked at water inlet at 92 k. New plugs installed then. Replaced all coils at 115 k. No other parts or problems except normal maint. items. Has been a very reliable vehicle, not sure what issues is referenced. Know about spitting out spark plugs but has never happened on this one.

Like the problematic twin clutch tranny in the now discontinued Ford Focus that always exhibits clutch chatter and why I have a Focus RS Turbo with a single plate dry clutch 6 speed close ratio box.

Had a 2012 Focus, dual clutch replaced 3 times in 39K. Last time traded to new Escape. What a POS. Those Focus RS Turbo are unbelievable, Drove one of my friends for 20 miles or so. Amazing what that Focus was capable of!!

I haven't come across any OEM tires on any make or model of new pickup (other than something like TrailBoss that comes on 3PMS Duratracs) that has a tire suitable for snow.

The Chevy's that replaced the Fords with had decent tires.

I bought my first turbo diesel 24 years ago. Having pulled loads with big block V8s for years, it was a revelation to drive a truck with an engine that didn't have to run at 3000+ rpm when going up a steep hill or pulling 20,000 lbs. This little 3.5 Ecoboost is tuned to pull the same way. Lots of torque down low, below 2000 rpm. Transmission doesn't need to shift down when pulling a steep hill. As you say, it pulls like a diesel! One big difference though. Hook my turbodiesel to a heavy trailer and the fuel mileage will drop maybe 4 mpg. Hook my F150 Ecoboost to a trailer and the fuel mileage (21 mpg not towing) drops in half.

OK, general question, even though I'm quoting deserteagle71:
If this 3.5 Ecoboost can pull like a diesel, then why are they building 7.3 Godzilla engines? This is 446 cubic inch of pushrod tech. The hp numbers are almost the same, but torque actually favors the 3.5.
3.5
Horsepower: 400 horsepower at 6,000 rpm
Torque: 500 pound-feet at 3,100 rpm

7.3
Horsepower: 430 Horsepower @ 5,500 rpm
Torque: 475 lb.-ft @ 4,000 rpm (<2023) 485 lb.-ft (2023+)

I've never driven anything with the 3.5, but have a 2022 7.3. Why not make the 3.5 available in the SuperDuty? The mileage would be better (at least in theory). I wonder what the torque is down around 1000-1200 rpm, like when you first take off with a load.

The 3.5l eco-boost is good for the F150 and that's about its limit.
Numbers alone do not decide application.
My 6.2l F250 pulls 11.2k to 11.7k or so during shredding season. I have to set cruise control to 60 mph cause it'll hit 80 in no time.
Yet, when getting settled in to unload in a unimproved pasture, the low rpm grunt of the 6.2l makes this an easy peasy task.
The 3.5l would not last in those conditions, nor pulling a 14k cattle trailer out here.
Lots of turbo load on those cute little pistons and con-rods, yeah don't think the Ford engineers designed them with low speed high torque demand on long stretches of highway in a super duty either.

Now on the other hand I've learned from a fella on a truck channel that Chevy's new 1500 has added a 2.7l turbo that is built ground up on a diesel platform, made to be solid performer.
Yet Chevy still uses a 6.6l gas and a 6.6l diesel, for the 2500.
This may still not be enough to answer your question, but it was the best I had! heh...have a good weekend y'all...
