I bought my 2013 brand new, and have enjoyed her for a few years now I've had the oil changed regular swapped air filters and done a reasonable job taking care not to abuse her, but she's getting older and currently has 180,000 on the ole ticker. I'm hoping she will be good for many years to come.

Here lately I've been trying to figure out why she's not getting the mileage or towing performance I came to love when she was new. Other than tires she is bone stock. The last set of tires I put on it were 275/60 18's and that's 1.5 sizes larger than stock (265/60 18 I think), so I expected a downward shift in mileage, but before 22mpg was mixed driving and a few spirited starts. Even after the tires 20-21 was expected if I wasn't hot footing it. Now 18.5mpg is a good day. I have logged over 5000 miles towing various things from rock crawlers to campers to equipment. I've hot footed the thing with my +8000lb camper (+80mph) with no problems, but lately getting up a hill (small hill) in 5th gear without loosing 10mph or causing coolant temp to rise is hard. I feel like before that was never a problem.

The truck still runs great, but it just seems she's missed a step or two the last 2 years, and I would like to see her 100% or better.

I recently had the low boost code pop up pulling my camper home one weekend so I replaced the electronic BOV which had a tear in it. Mileage and performance showed slight improvement.
Other than that I just replaced the plugs and gapped them down to 28 thousands.

I have no codes popping she idles smooth and pulls pretty dang well, but I see what other ecoboosts are pulling in much more extreme environments. Based on the performance from Memorial Day weekend mine isn't up for that. I have the smaller gears, but 3.15 in 4th is 3.591 and 3.73 in 5th is 3.2451. Knowing that I have expected to use 4th and 5th more than say the max tow would from the beginning, but she pull loads much better once upon a time.

Surely the tires aren't the problem here... are they?

Things I'm considering both to restore factory power and upgrade:

Clean innercooler possibly upgrade
Go back to stock on tires
Tune
Maybe down tubes
Maybe exhaust if I can find a quite freer flowing combo


Bigger camper once I'm confident the beast will drag it just fine.


Some tow mileage history

10mpg towing 8000lbs of rockcrawler and trailer through West Mississippi hills through Natchez (pre mileage and preformance issues)
12mpg towing 7000lbs of truck and trailer through low rolling hills of Mississippi (pre mileage and preformance issues)
8mpg pulling +8000lbs camper hot footing it across the flats running 75-85mph (pre mileage and preformance issues)
9mpg pulling +8000lbs camper to Dauphin Island and back (pre mileage and preformance issues)
8mpg pulling +8000lbs camper to Dauphin Island and back but babying it this time
7.5mpg pulling +8000lbs camper low rolling hills of South Mississippi not quite babying it (after bov and plugs were replaced)

Unloaded through the Smokies I cruised at or below 65mpg and managed to get just over 20mpg after I replaced BOV.

I'm interested in maintenance suggestions. As well as upgrades. I'm gonna be up front about the catch can thing right now. I think it is a solution needing a problem, and I've lurked here for a long time and I'm not convinced it brings any attributable value to the life or performance of any engine. We can be friends and disagree... I hope.

So other than catch cans whatcha got?

You have 180,000 miles on your Gen1 and you are asking for advice?

I'm asking FOR advice from YOU! :)

Man would I love to know definitively what leads to one Gen1 delivering a long and reliable service life VS one that crosses that 5year/60,000 mile benchmark and suddenly frightens the owner out of confidence.

Best advice I have is change the oil often and drive it like you stole it once or twice a week. I drive roughly 40,000 miles a year (I bought the truck as new old-stock in 2014). Its only on its second set of tires and breaks. They are great trucks, I know there are some turds out there but in think their are far less turds than the internet would have you believe. I've replaced two other components a coolant line seal to driver turbo and one of the MAP sensors. All in the last year.

I would like to go on record that I have never met you, messaged you, or prompted your reply even the LEAST bit!

Yet you immediately described your ownership experience as Lots of fresh oil AND running it hard a couple of times weekly.

Amazing!

Why? Because there is a similar description almost every time someone checks in here and announces that their truck, or their dad's, or uncle's...... Ecoboost has 200,xxx miles and is "still going strong".

I realize that what I'm suggesting isn't some kind of magic solution to a trouble free Ecoboost guarantee, since it wouldn't and couldn't address the occasional manufacturers defects that are found on some percentage of every make and model. But I don't think it's a coincidence that these Ecoboost trucks were designed to perform, and indeed suffer WELL for doing so.

That and Lots of fresh oil.

I tow a little #5000 TT and I can only manage 10 mpg on average and that's not really going faster than 65 mph. I can get 20 mpg on the hwy unloaded if I keep it under 70 mph. Once I go over 70 the mpgs tank..

I've got just over 75,000 miles on my 13 now. Bought it brand new in early 2014 with only 56 miles on it.

I do 4-5k oil changes with Pennzoil Platinum. Use the MC 500 oil filter. I've done a drain and fill on the trans, trans case, rad and the rear diff. I know I should do the front diff too, but didn't feel like taking all those covers off! :) I've changed the plugs twice now. Set mine at .030 using MC plugs.

I'll be happy to get another 100,000 miles out of this thing without any major issues.. I try to deal with all the fluid maintenance stuff regularly as it's just fluids and pretty cheap in the long run..

I don't have a can, no hole, no tune, MC air filter.. Daily driver too.

I've learned a lot more after getting the Torque Pro phone app and a ODBII plug in to monitor a TON of sensors and I now know that when towing to let the engine rev around the 2000 rpm mark for the most part.. (for me that's 5th gear) and going up the grades in 4th (2500-3000 rpms) and everything stays nice and cool and running smooth with lots of pedal left if needed.. But, I don't need to fly up the grades... An easy 60 mph is just fine for me..

My specs are in my sig and I'm more than happy with it's daily and towing performance. :)

Your method of towing is similar to mine. I’m not trying to chase down the diesels but I perceive that I once had a little more pedal. Maybe it’s all imagined, but the mileage isn’t imagined and I knew something wasn’t right before I logged the low boost condition and the truck ran perfectly fine just less power once I had a place to look I found the problem. I’m hoping if I look a little more I can find another week link and retake a little ground.

I wouldn’t say lots of oil for the first 140k I reset my OLM to 100%. So every 10k I changed the oil. Well I paid the Ford Dealer to do it for me. I will also confess a significant amount of my driving is cruising speeds. Which is much easier on a motor and transmission than stop and go. It also gets to operating temp and stays there for almost 2 hours daily. I can be a little rough on equipment though and occasionally push the limits a prime example was running it hard with my camper because I was an hour behind schedule.

That probably has a fair amount to do with it. And my tires are a whopping inch and a half taller and 10mm wider than stock so it’s almost not worth mentioning. Except it throws off the speedo by 7% and is a little extra rotating mass.

I failed to ask yesterday on the trans fluid. Did you see a difference with fresh fluid? Ford at one point said only severe duty required changing fluid. Have they walked that one back?

If you mean a difference in mpgs with the trans fluid change, then no... I don't change the fluids to see a change in mpgs.. I change the fluids to see my odo miles go into the 6 figure range like you have gotten!.. :)

I just got back from a camping trip of some 400 + miles and only got 10 mpgs, but my trans temps, coolant temps and just the overall performance of the truck was great as always so I'll keep the fluids fresh and just not worry about the mpgs.. ;)

Sure, I like to get good mpgs on my daily commute and I get what I consider good mpgs doing that (16-17 mpg). But, when towing, it's towing and it is what it is and that's all that it is. :)

Its not just the miles per gallon. The miles per gallon appears to be a symptom just like not having as much peddle as I once had. I’m looking for ideas. Ford says the fluid is good for the life of the truck unless severe duty. More than 97% of my miles are unloaded it’s the trans had never run hot or even come close to it, however I may have the dealer drain and change fluid to inspect the molded frame in the trans since Ford is providing the extended coverage.

Anyone have ideas on parts to clean or replace?

Gottcha... You might have the 'coked' up intake valves that these GDI engines are known to get over time?? That could cause the lower performance you are experiencing.. Think of it like being all congested and then trying to run a 5k run! ;)

Since changing the fluids is pretty easy, I consider it a basic maintenance thing. I do it the old school way of thinking, since I'm pretty much from the old school days of carbs and points.

Good luck with it!

I don't think Ford will do anything with the lead frame thing until you get the dash warning light, but can't hurt to ask! (I got the same letter about the lead frame and still waiting for the software bandaid for my 13)

Have you checked the compression on the cylinders? Also, what does your boost psi look like? Your turbos might be getting tired.

Never considered compression. The truck runs really smooth just doesn’t pull like I remember.

I have the Torque Pro but rarely use it but I hooked it up for a few minutes this morning.
My old android phone seems to have lost all my PIDs but I was able to get “Intake Manifold pressure” and “Turbo Boost and Vacuum”. The intake manifold read constantly higher than the other. I’m not sure of location on either. I assume the intake manifold is the one on top the manifold and behind the throttle body. The second is on the charge pipe. Memory is a little fuzzy but it shouldn’t be hard for me to locate. Here’s what I thought was interesting and I don’t recall this before. The manifold consistently read way over 13.5psi. While the boost/vacuum gauge would only peak at 13.5. I didn’t have a long straight away to make sure it would hold 13.5psi so I’m not ready to say it won’t but that was a problem before I replaced the BOV earlier this year. I would like to think under normal conditions the manifold would be slightly lower than the charge pipe not massively higher. Looks like it’s peak was 28-29psi. Which is way out of spec but no check engines and no faults.

I’ve wondered about the valves but I just assumed it would come with a rough idle and it’s been smooth as glass since I put plugs in it.

I would for sure go for a 5 star tow tune. I think you will be very happy with that.
I would change and gap plugs, coils may be getting a little tired on you, clean MAP sensors. What octane gas do you run? Maybe run a few runs for the Italian tuneup? ;)
Id also check to make sure you are running full boost. Check your intercooler boots, take them off and clean them. I went through and replaced all the clamps on mine. Just didn't trust those type of clamps lol

A good ole Italian tuneup. I try to do that at least once a week.

You know the Octane may have been a factor the other day. I have a fuel card from work so I normally run 87, and I “may” have burned company gas on that last trip towing. Does it make that big of difference towing. I’ve never noticed a difference empty so I never gave that much thought.

Yes it does from what I have experienced. For me I always run 91 even on the stock tune. I noticed with 85 (here in CO) the truck was a dog. Could not stand it so I only use 91.

When I did my tests with different octanes while towing I found that the engine seemed to run a little cooler the higher the octane. The PCM can advance timing more, for a longer period of time on the higher octane. I found only a slight difference between 87 and 91 that is blended with ethanol. However, if you can find NON-ethanol 91-93, then the differences are much more noticeable. The cost of pure gas however negates any savings over blended 87. In fact, it may end up costing you more because you don't gain an equal amount of MPG to make up the difference.

Now if you routinely ran 87-89 in the past, you shouldn't have to put higher octane in the tank to "regain" performance from before. So if your habits haven't changed, but the truck has, then I would still focus on fixing the truck's performance.
