hey guys just bought a new f150 with an EB. Did anyone do anything special for break in or just go with the good old break it in fast and she'l last break in slow and she'l blow lol

 

They're mostly broken in right off the lot. Most important these days I think is to vary the speed for the first couple thousand miles. If you're doing freeway go 55 then 65 then 50 then 60 and so forth. Don't hold the same speed for more than three to five miles. Mine 2013 now has over 30,000 on it and runs and drives great, gets incredible fuel mileage and doesn't use any oil. Most of all just enjoy your new ride.

 

Drive it like you stole it...

They are run in at the factory to prevent imminent destruction by the mishandling of a new owner. Although you could take it easy on it to let the drive train marry up properly. [you know... no burnouts, 20000 lb towing up hills, etc...] Watch the gauges and pay attention to it for the first 1000 miles, after that, it should be all good to go.

Several trucks, million+ miles and never lost a truck engine or tranny. Biggest thing you can do is be very faithful to the oil changes and do them at 80% recommended miles if you gonna tow alot, 50% if you tow heavy. I highly recommend Synthetic but I am an old dinosaur and remember the days of old Quaker State Sludge in the valve train and promised to never use it after I found Synth...

The Owner's Guide for my 2012 EcoBoost does not have any breakin procedures, as such, in the index. But it does have a big no no in the towing section: DO NOT TOW A TRAILER UNTIL AFTER THE NEW TRUCK HAS AT LEAST 1,000 MILES ON IT!

With other vehicles over the years, I've learned that the best breakin procedure is to go to town and drive around in city traffic, with lots of traffic signals and stop signs. Baby the brakes as well as the go pedal for that first 1,000 miles. Get up to the speed limit when possible, but anticipate stopping for red lights and stop signs, and decelerate with throttle off as much as possible. And use the brakes as little as possible. Of course that means you will constantly vary the speed and engine RPM.

If you can't do it right, and simply must drive the truck cross country before it has 1,000 miles on the odo, then set a routine where you vary the speed every 5 miles or so, and take every exit. For example, with speed limit of 70 MPH, drive
55 for 5 miles
65 for 5 miles
74 (or the ticket limit) for 5 miles
60 for 5 miles
70 for 5 miles

then repeat the sequence.

When you see an exit ahead, if traffic allows, decelerate with throttle off as much as possible. But use the brakes as little as possible, and always lightly. The vacuum caused by throttle-off deceleration does wonders for sucking oil up around the rings in the combustion chamber.

 

Drive the crap out of it. I got my Livernois tune with 500 miles on it.

 

That didn't take long . . . .

Read the owners manual. Follow it. Common sense says ease into it.

 

If common sense was common, they wouldn't have needed to put it in the manual... ROFL..

Wow, it didn't take too long to offend. Owner's Manual has nothing about break in. (just as Smokeywren said) Perhaps a good read of the entire post...LOL

I did say be easy on it... but not for engine break in purposes... that is already accomplished.

 

I've had my '13 EcoBoost FX4 for a little more than 2 weeks now with roughly 670 miles. I drive the hi-way everyday for work and vary speeds as much as I can. It's only a 15 min ride to work. Otherwise...I've pretty much baby'd my truck. I've driven it very conservatively so far except when I first get in it in the morning for work. Love hearing the turbos spool!

 

I've seen people buy a truck, drive it 2 miles home and hook up 15,000lbs and 4 years later they've got 200,000+ miles and no issues. On the other hand I've seen someone with less than 500 miles blow an engine while just cruising down the highway.

I would say drive it as you please, so long as your not overloading the vehicle it's not going to matter. And from my experience the easiest way to break the vehicle in is simply to get the engine/powertrain nice and hot or normal operating temperature and then let it cool over night. Which would be in line with varying the speeds to an extent. I generally don't tow for 500 miles, but I run the truck normally such as WOT to merge onto highways/interstates and I set the cruise and let it do it's thing. I do change the oil between 2500-3000 miles and use synthetic oil. My current Tundra oil was changed at 2800 miles, she's at 8800 miles and oil still looks very good but is due within the next 1000 miles. As far as break in, I hooked a 9600lb travel trailer up to it with less than 750 miles and that was a good break in.

 

JeffD, shipsgunner comment is the closest to reality, and the best for the longevity of an engine: drive it like you're going to drive it. Period.

If you want the low-down on real-world engine break-in, go here:

If nothing else, at least change out the factory oil and filter at 500 miles to get all the milling chards out of the engine (when you do, look for the "glitter" in the drain pan when you empty the into a recycling container!)

Enjoy!
