Wait 1000 miles to tow with new F150 EB?

I waited the 1000 miles as the manual says. Was actually hard to get the 1K on before our first trip 4 weeks after we purchased. All I can say is it towed great! Don't want to do anything that might void a repair. I wonder if the system remembers when you've had a trailer hooked up. It's certainly integrated into the info system.

First tow saw 9.6 on way out and 9.8 back on 500 mile trip. Flat land down I-10 to Pensacola but nice to keep it in cruise the whole way and never have crazy downshifts that I used to with my Tahoe.

I'll go easy on it as I always have anyway. I have no reason to beat on a brand new truck while towing.

Wonder if anyone ever breaks in their new 'leather' shoes anymore?

Don't know about you folks, but the world where I live...things do wear out and
faster if exceeding their design parameters

Really boils down to both things mentioned...the OEMs want you to buy again
So no incentive to make them last, plus many folks trade ever few years to leave
the next owner(s) to deal with design margins consumed

Other is that material and production/process science has greatly improved.

Seldom do I 'hear' a whining rear end these days, but have been asked about that
many times both here and over at my forum

Either they didn't break it in properly (towed heavy too soon) and/or did not
maintain it according to the manual (flush)

Anyone remember that 'cars' used to considered past their prime and ready to
be retired to the junk yard at 100K miles? Both material and process/production
science better now then back then. Ditto changing the engine oil every 3K miles
(synthetics did NOT exist back then)

The Ecoboost engine has NO break in period but the differential DOES have 500 mile break in before towing (just like every other brand of truck).
Good luck / Skip

I would follow all of the manufacturers recommendations regardless of why they make them. We cannot know why they make that recommendation other than what is included in the manual. There could be more to the story or nothing to it, but their engineering group obviously wanted that initial short break in period for some reason.

Mostly it is the ring gears to finish the surface hardening process.
Most are 500 miles. Go easy and you will be fine.

Don't know what your manual recommends in 'tow section'

Mine is a different make/model but in manual it clearly stated 500 miles break in prior to tow/haul.
It is to set the rear ring gear/pinion.

I had that mileage 2nd day just running around showing family/friends.

City and highway speeds.

Easy thing to do..........

I used to be into BMWs and when BMW started including the maintenance in their price, the break in period/service went away and all the service intervals went way up. Most of the fluid changes became lifetime.

If it were me, I would vary the RPMs and do a break-in service around 1000 miles draining all the fluids and refilling. However, if you sell/trade-in like most in 5 years then its probably not worth worrying about.

X2 - New mechanical devices have increased particle counts in their oil from natural break-in processes. The particle counts are detrimental to long term life of the product. The first oil change in all the vehicles engine or all gear boxes is most important for long life..... :B
