Hi everyone,

Just took delivery of my 2006 GT. The owner's manual recommends a 1000 mile break in peroid. I have about 630 miles on it now and can't wait to really get into it. I was just wondering if the 1000 miles is a must or does it vary?

Also, I've also heard stories of our cars getting a little faster as we put more miles on it (possibly due to breaking in properly?). Is this true or just wishful thinking?

Thanks in advance.

1000 miles is pretty standard. The better the break-in the longer the engine will last. There are some on the forum that will say they don't worry about breaking in the engine and just drive it hard since day one. Like shoes, an engine and tranny require some breaking in, otherwise they may get trashed.

And most cars will experience an increase of performance after a few thousand miles as the parts wear-in, the computer calibrates itself to your driving style, and there is less friction from new parts. Take a look at any long term test drive article (like Car and Driver or Road and Track) They test the car brand new, sometimes midway, then when they get ready to wrap up. Most of the time they experience better performance after a few thousand miles. Not always.

Cool, thanks a lot. Can't wait until 1000.

I say if it can survive the first 1000 miles under hard driving conditions, then you have a good engine and tranny.

I'm no expert, but I'd think you'd be fine after 600-and-whatever miles. I know 1000 is the rule, and probably has been since the first mustang rolled off the line, but I get the feeling that with modern manufacturing we're producing parts with much greater precision than we were then (robots make everything, and they have, like, lasers and stuff that they use to measure everything.) Plus I'm thinking an aluminum engine would break in faster. So I say GO FOR IT!

At least, that's what I told myself when I got to 500 miles and couldn't hold back any more

i was pretty easy on her up to about 1K, but I did hit it every once in awhile. I just did my first oil change at 1,500miles and the next at 3K will run Mobile One

I think I made it to about 800 miles before completely breaking my foot off in the throttle..My god its addictive!!!!

I had the same question and asked the lead mechanic of the dealership I picked my car up at. My concern was that I was going to drive the car from the dealership in Georgia back to my house in NY, about 900 miles. I was told not to worry, just not to "be ******* it". So I just kept it between 50-80 on the highway being sure to keep changing up the speeds now and then. It was interesting to hear how the exhaust note had changed from when it left the lot to the second day of driving after it had hit 600 miles or so. Now I have about 2000 miles will be changing the oil real soon and cutting over to Mobile 1.
I had also purchased a Volvo for the wife recently, when asking about their break in period, was pretty much told not to worry as well.

What is so stupendous about mobile1? I'm getting the oil changed tomorrow.
