Skyactive engine break in

[erhayes]

I totally agree that too gentle or to aggressive a break-in protocol is not good. I have always had excellent long term performance with a medium/normal driving break-in. I have never heard of or observed anyone with 150,000 + miles, state that they used a "drive it like you stole it" break-in.

Well, by the definition of "abusive" I would have to agree with you. But the difference of opinion I see between the gentle break-in crowd and the "to the max" people is what constitutes abusive?


It could be argued that too gentle of a break-in is abusive and I would agree with that. If I had to pick one or the other I would err on the side of hard. But, as I've said, just driving it normally is the best.

Simply following manufacturer instructions is best. They know what they built, and they don't want to pay out any more NVH or whining/whirring or grinding or oil-burning warranty claims than they have to.

Oh my, where to start ????
# 1- >Airplane engines? Nope.< from http://www.avweb.com/news/maint/182895-1.html
"first flight ... closely monitor RPM. If it doesn't get within 100 RPM of red line and there is sufficient runway available, abort the takeoff.

#2 &3- >Industrial engines? Nope. Expensive Diesel engines? Nah < (many industrial engines are diesel so I lumped them together)
Copied from Cummins Break in Recommendations
"Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detrimental
and should be avoided."
And......... their Diesel Supplement...
"The diesel engine does not require a break-in period due to its construction ...."

#4- >Race-car engines? No, Sir!<
So what is an hour or more break in run or 3 on a engine Dyno for ????

>What have you ever seen break-in properly like this? Anything?<
Yep, seen it an done it. I try to keep a open mind and learn about advancements in technology stuff.
FWIW One must read and view all the multipaged Mototune articles and videos, then find feedback from people who have tried it before jumping to century old conclusions.

>Everything from an airplane to an RC car<
Having flown R/C airplanes for years and been race support for kids oval, road course and off road in ele. and some gas.... yeh... umm ... r i g h t

I am curious.... since I'm happy with my break in and you're not,
have you taken yours to the dealer to find out what may be wrong with yours?

Nothing is wrong with my vehicle, and I bought it used, so your point is lost on me, that last bit.

I can tell you on the new 370Z and new Z06 that I bought they did GREAT! The 370Z was actually killing E92 M3's on the freeway, and the LS7 in my Z06 didn't use a DROP of oil, Neither had a single whine or other harmonic from the driveline, at any speed accel/decel or rpm, either.

Ok, read this thread from the beginning and now realize I made a oops with another thread on low mpg complaint , I apologize for the take it to the dealer comment.

Now reguarding your comment.............. "This method is the height of stupidity. That is NOT how you break an engine in".
I copied this from your previous post "I recall reading to vary the speed/rpm, vary the engine load, but do NOT lug the motor, ..."
Sounds pretty much the same as Mototune talks about on his site to me, so you must have broke in your new vet almost exactly like I did the CX-5

That is what I have done during my life. I just try to make sure I vary things up during break-in and no full throttle starts.

Put it in neutral, rev till redline and then throw it in drive. Repeat for 20-30 times.
Seriously, read the owners manual. When other people say to do one thing contradicting what the owner's manual says, ask them to see their master's degree in engineering. Until those people have ANY idea about the engineering of our cars, stick to the guys smarter then you. They know what they're talking about.

On a similar topic:

Do you change your oil earlier on a break in? If so, how much earlier?

 

[erhayes]

I changed at ~ 1/2 the 7,500 miles service I would be using. Probably a total waste of money but, did it. I certainly think the 1,000 FF change is foolish.

Engine Break In

I read that, but it seems like some people say drive it hard sometimes.

Allow me to shed some light on this. I like to ride motorcycles, and the proper way to break in a new motor the manufacturer indicates to use variable engine speeds. In other words, don't keep it at 2,000 rpm all the time. Don't be afraid to get on the throttle to get it around 4k for a short distance. Keep the motor guessing of what your going to do next... I hope this helps you or someone. And we just buy a brand new 2016 Touring model this weekend 8/22/15. It is a nice machine... Cheers.

I noticed an improvement both in mileage, noise and performance after the first 7500 mile change. So the benefits can likely be had earlier.

It has been discussed a lot in many forums and last line always is....... If in doubt don't try it.

I've personally use this method to break in three new motorcycle motors (two brand new from the factory and one rebuild) and one new CX-5 motor. None of them use a drop of oil between services, and all run very very well. One of the motorbike engines has been in service for over 100K miles and 10 years (and is a thumper). Another has had an even harder life with over 50K miles in 3 years. Not a single motor related issue.

One thing a lot of people forget is even a new motor has already been run-in on a dyno at the factory. There isn't one manufacturer (that I know of) that will assemble a vehicle and sell it before putting it through it's paces on a dyno (engine or chassis) to make sure everything is within spec. At that point a lot of the engine break-in has already happened.

^^Exactly ! Anyone ever watch those video clips “How Dream Cars are Made” ? Every single one of those engines being built on those super cars they break them in by putting them on a Dyno and Wide Open runs till red line and all kinds of stresses on the motor.

I had a tune on mine before 300 mi lol.
