    turbo break in?

    i'm sure there's no turbo break-in, but my turbo just sounded louder after 2K miles.

    i did an oil change myself at 1.5K miles with Mobile-1. then after gotten a full tank of 92 at costco, my muffler suddently sounded louder when i have 2.5K-3.5K RPM on second and third gear.

    why is that?

    The muffler bearings take a little longer to wear-in than the rest of the car.

    The Knack. It's a rare condition characterized by an extreme intuition about all things mechanical and electrical ... and utter social ineptitude.
