I get my 2016 F150 this Friday, and was wondering what techniques some of you have used to break the power train in.

It's a 5.0 with the 3.55, 7000 gvwr just over 200km, 120mi on the odo, brand new.

Elevation is around 3500 ft.

 

Just go drive it. It's gonna be fine. It's not the 60's where you had to break in cams and seat rings.

 

Get on it a bit, vary speeds and rpm and don't tow for 1000 miles. Simple as that.

 

With 120 miles already on it, who knows what it's been through? Kinda difficult to bring back it's virginity now. But I get what you're asking...

Mine had 50 when I took delivery. I had elaborate plans for breaking mine in but, realizing that it had already been "soiled", just kept the RPM under 3000 for the first 1000 miles and varied it when I could by locking out gears. I then changed the oil and filter at 1000 miles and called it good.

FWIW, my 5L's dipstick went from top of the full mark to half way to add over that initial 1,000 mile period. At 2k now. The oil level has remained at the full mark for the past 1,000 miles.

 

Hit it like a rental. Did that with multiple motorcycles I have owned and new vehicles. Vary RPMs, you'll be good to go. Oh yeah, follow the break in guide. Didn't tow anything. ��

 

I would check the owners manual and follow what it states.

The goal of engine break-in is to operate the engine in such a manner as to promote good ring/cylinder bedding.

Pretty much you want varying cylinder pressures/vacuums to get that bedding done correctly without exacerbating any hot-spots at the ring/cylinder interface.

If those hot-spots get overly hot, the two metals wear excessively. This probably won't become a problem in the following 200k+ miles of operation, but it never hurts to try and start out on a good foot. That's why there is generally an RPM limit during break-in; higher RPM = faster moving pistons = more heat at critical wear-in zones.

I'd trust the folks who spent the millions to engineer, design and produce that engine to know what's best for it, or go with some other form of gentle break-in that is at least as restrictive as what the owners manual states.

Owner's manual tells you exactly what to do.

 

Thanks for all the replies, sounds like I'll be taking the book out before I get her home.

 

I have had 3-coyotes and I drove them the way I was going to drive them with 120 miles or 23,000 miles. Vary the rpms no cruise control for the first 1000 miles.

 

Or you can go here, download your manual, and read it before you pick it up.
