new mach1 break in procedure

[s650user]

I just bought a new 2022 mach1 with handling package. I did not expect my car would come at this time. It’s already cold where I live and am going to keep it in my garage until next spring. It has 15 miles on the dash. Can I still follow the break in procedure when I get it out in spring? Do I need to do anything special while it sits in my garage through the winter? Should I need to start and idle the car for some time once every week?

Should I need to start and idle the car for some time once every week?

That is the absolute worst thing you could do. The rings will never seal and moisture will build up on the cylinders. Park it and wait till spring, or a warm day when you can drive it for at least 20 miles non stop.

Personally I break them in like I'm going to drive them. Ford runs them in at the factory.

Drive it

If you’re not going to drive it, install jacking rails ang put it on stands to reduce the chance of flat spotting the tires. When spring rolls around, run it as hard as you like without worrying. If anything happens, you’ll be covered under warranty.

If you’re worried about flat spotting the tires, you can also pump them up to just under max press like Ford does for transport.

I can’t honestly say if starting will hurt it or not, but seems logical it’s not a great idea, given Ford suggests driving it at a variety of RPMs.

There's no such thing as flat-spotting tires. At worst, it's a temporary thing that goes away in 15 minutes of driving.

You car came with Cup 2 tires I believe. I'd be looking into getting some MPS4S tires.

Just drive the car like you stole it, don't baby it. Beat on the engine right away.

Don't start it during the winter, just park it inside after a good wash and overinflate the tires a little bit (I do mines at 3 bars).

Charge the battery once every month or connect a battery tender. Most modern good quality chargers have the functionality of battery tender built in.
If there are good sunny days without salt on the road drive her to make at least 15-20 miles to warm up everything really good.

Do a proper break-in period for the first 1.000 miles as the manual states. Don't put too much strain on the engine, just be light on her for that period and all will be good.
Don't ever trust who states to hammer down a new engine, that's a very bad practice.

People talk a lot about break in here, as if there is something specific to do. I tend to think of break in as something that happens, not something you do.

If I was OP, I'd probably just park it if you're not planning on driving it in the Winter. Then get her out in the spring and enjoy

@s650user only additional thing I do in addition to what’s mentioned is run stabil through the system to a full tank. If you are a manual, leave in neutral, no e-brake, block the tires and cover it

Welcome to the forums.

There are several threads on both storage and break-in you can search for and read in detail. The comments above provide a great summary.

Agree with @K4fxd . Your piston rings in-particular have yet to completely seat. If you cannot consistently take the car out, bring up to full temperature and stress it, you're better off stowing for the Winter.

In the mean time, you can cruise the threads and study what others have done past for best break-in.
