How about a topic covering the best way to break in a new motor. Thought it might be a worthy topic for all these new Mustang owners (for some maybe their first new vehicle ever).
With my new vehicles I would always go real easy on them the first 0-300 miles. Let the seals valves etc.. get seated good and tight.
Between 300-400 miles I would start to push the motor especially on freeway enterance ramps...gunning her hard through the gears then backing off.
400-500 miles I'd mix city stop and go along with even harder acceleration on freeway enterance ramps coupled with some long highway cruises to get that motor to behave just the way I'd like to for as long as I owned it.
500 miles change oil (I always perferred Valvoline myself).

This always worked well for me. Anybody have else have tricks or secrets you wanna add.

 

Yes - FOLLOW THE DIRECTIONS IN YOUR OWNER'S MANUAL.

I'm not trying to be a smarty - I just think it's wise to follow the manufacturer's recommendations in this area, if only to avoid potential warranty issues down the road.

Good luck with your ride!

 

drive it like you stole it

 

Really? :shock:

Would you really advise that from day one? I sure wouldn't.

 

Exacta-mundo.

 

[COLOR=#0000FF]In the owner's manual i perused from the website, it says that no breakin is needed just to not drive the car at the same speed for the initial mileage. I took this to mean that they suggest to not immediately hop in car for crosscountry trip and set speed to one constant limit with no variance. But instead drive at a normal mixture of highway and city driving at varying speeds.

I think most would also suggest not redlining a vehicle for a set period too. It suggested on my current car to not go above 4500 rpm for the first 1200 miles. It took soooo loong...he he

Although the Mustang manual suggests no breakin is needed for the engine, usually a breakin is required on brakes and tires to be most effective.

 

My new Mustang is my 4th new Ford since 1988. With each one I followed the owner's manual's recommendation by not driving at any one constant speed during the first 1,000 miles. With the commute I have, that's pretty easy to do. Out on the highway I would constantly fluctuate between 55 and 65. 60 for a while, down to 55, up to 65, etc., and I wouldn't use the cruise control until after that 1st 1,000 miles.

My 88 Thunderbird and 97 Taurus each clocked over 100,000 miles without a single drivetrain problem, and so far my 2000 Taurus has reached 65,000 miles without incident. I change the oil every 3000 miles, transmission fluid every 30,000 miles and coolant every 50,000 miles.

After 3 weeks, my Mustang's odometer reads 1,060. I can use the cruise control now!

 

Man, I am having a seriously hard time breaking this thing in. I got on it pretty hard (hitting 5900 RPM's) threw first second and third after only 200 miles. I can't freaken help it man. Some one told me that they run the motors at the factory for a certain amount of time to break them in. Anyone know of this?
