0ptimun performance mi

My car has already 3000 miles. At what milage can I expect to have the car fully broken in and get optimun performance?

I noticed a progressive improvement up to about 5k miles, both in ride quality and reponsiveness. Dunno if my getting used to the car had anything to do with it as well. Seems to have plateaued or very minimal after that. Then, wear items will let their presence known. I am now up to 17k miles. My pads are quite a ways down, with noticeable degradation in braking ability. I expect it to be back up to par after pad and rotor change.

It probably varies with how your car was broken in and how you drive it. Seat of the pants impressions are obviously subjective but I noticed that my engine felt more free revving and stronger after about 10,000 miles. I've seen long term road tests of cars where the 0-60 times at 35,000 miles were actually quicker than when the same car was first tested, so there is some objective evidence that a few miles may actually improve performance. :cheers:

I agree there. I noticed that on my Boxster too before I traded it in on my current car. I had 17.5K on the car and seemed more responsive to my foot and felt like it had more HP. I guess I'll have to wait for another 16K miles or so. :rolleyes:
