A question about breaking in a new engine
Hey I just read this post on the DIY section that says it is good to run the engine hard to break it in because it helps the piston rings seat properly.
1. What thoughts do you guys have on this???
2. How (and for how long?) did you break in your enginer??
3. And how soon was your first oil change??
Why yes.... I AM a rocket scientist!

Re: A question about breaking in a new engine
1.) I don't like the article. If an engine is rated for 280hp, it puts out 280hp. All engines (unless otherwise specified) are machine-built and spun at various rpm's at the factory to break the engine in properly so that they all put out their rated horsepower and so they are "pre-broken-in" properly.
2.) I took my engine to redline at 250 miles, 500 miles, and 750 miles, and then a little after that I just drove how I wanted to. My little "schedule" was purely out of not being able to hold back anymore. I always made sure to vary the rpm's on the highway, though.
3.) First oil change was at 3,750 miles, as specified in the owners manual.
Let me say this in my own words:
Running the car hard from day one is quite possibly the dumbest thing you can do. Your gears need at least 500 miles to break in. Your brakes and your tires need time to break in as well. I'm not saying that it's bad for the engine to run it hard from day one (that issue is contraversial), but gears, tires, and brakes NEED the break-in. If you want these parts to last as long as they are supposed to, break them in properly (tires need about 50 miles, brakes need a couple hundred miles, gears need at least 500 miles).
The best advice is this:
-Follow the break-in instructions according to your owner's manual. Don't listen to some wack mechanic who lives off of fixing cars.
-Always warm up the engine properly. Start the car up, let it sit for 30-60 seconds and then drive it gently (no going over 4K rpm, no hard acceleration) until it is fully warmed up. This is something you should do for the life of your car, not just during break-in.
-During break-in, you do not need to "baby" the car. Just drive as you normally would while following the guidelines in the owner's manual.
