Break in period?

[JenneyD]

So there's two completely opposite schools of thought on breaking in a new motor. 1 that dictates you baby it for the first 800-1500 miles. The second is to run it hard!

The first theory from what I read is based on older engine models.
Supposedly on new model cars use a finer honing in the cylinders than they once did. Supposedly the window for achieving an optimum ring seal is much smaller when compared to older rough honed engines.

Just curious...by popular opinion? Gun it or baby it?

Just drive regular. 500-750 miles. Vary speeds. Take up to around 65-70 Mph most. Gradual speed increase. After that............."MUSCLE POWER".

Whats the owners manual say? I would go by what the manufacturer recomends for any car

Never heard of breaking in an engine by beating on it from day one :idk:

A couple of enthusiasts I've been talking to on another forum subscribe to this theory:

I've heard this theory off and on for years...but hadn't had a new car to "break in" so never paid too much attention.

OH...and just because you haven't "heard" of it doesn't mean the theory doesn't exist

Just because it exists also doesn't mean that it should be practiced

The response was to those that said they've never heard of it.
The theory does exist.

A couple of people from Lethal and IIRC JPC have said numorus times that they beat on their car like a raped ape from day one and have never had an issue. It is all up to you though.

I just want to do what's right for my baby lol Yes......I'd love to beat her..she deserves it for making me wait....haha but only when the time is right. Just wanted to get others' opinions

The motor has already been broken in at the factory threw testing after assembly. Drive it however you want.

That is also why you have a warranty. Congrats and have fun.

As much as I love this theory I know it's a bit of an Urban Myth. If you talk to Ford they only test the motor before dropping in ...they don't actually "break in the motor" although many of us would love to believe this! lol

and thank you!

You need to seal the rings against the cylinder walls. Varying RPMs is the best idea. Get your RPMs up every once in a while. Maybe a couple times a week and then baby it the rest of the time to break in the rest of the parts.

did the car come in yet?

 

[Wicked One]

I would just drive it any way you like. But what does the manual say.

I have always driven my new cars the way I would if they were old.

Nope big shocker- dealer says Ford is FOS...really?

You know what JenneyD, you are going to blow by 1000, 1200 miles in no time just aquainting yourself with your ride. I mean I'm sure your not going to do 200 mph without knowing your car. Drive it!!!!
