This car feels totally different after the 1200 breakin. The smoothness of the drivetrain has improved exponentially. The engine revs faster and transmission shifts very silk-like. I am getting up to 3 MPG more. The breaks also grabs more smoothly, no more judderring, but still stops on a dime.

Not sure if the synthetic oil in Engine, Tranny and Diff. is the main reason.

Anyone having the same experience?

 

Of course!

What you're experiencing is very normal. The car should be smoother and get better mileage after broken in. It will continue and then start heading the other way after xxx miles. I don't know what xxx is, but that's one thing that separates good cars from bad: in good cars xxx is a big number, in crappy ones its a small number.
