    The owners manual says 1000.

    Here's what I did.
    First 500 miles below 4000rpm
    501-750 miles below 5000
    751-1000 miles below 6000
    After that just keep it below 7000rpm (the red line) and you'll have an engine that's happy for a long time.

    Owners manual states keep it under 4k rpms for the first 1k miles and to vary rpms (dont cruise at the same rpm for long periods of time).

    On my STI I kept it under 4k until I got my first oil change (1,500 miles) then I slowly started to add more rev's into the mix.

    You will get people who drive the crap out of the car right away.....others take it easy.


    I researched it and did what is stated above...if your mech. is giving you a break in policy I'd follow it as he's more familuar with your setup then anyone else is.

    Worst case is you are saving gas for 2k miles....I do suggest however changing the oil and not really beating on the car till the "break in" oil is changed....if that makes sense.

    Oh, right, I also changed my oil at 1300 miles. It's a good idea, because it will remove a lot of the "new engine" metal shavings the rings and other moving peaces the engine is creating.

    so after my first oil change would that be a good time to get the protune?

    0-1k miles: factory break in
    1k - 3k: some spirited riding but nothing really hammering it
    3k - 6k: drive it like you stole it
    6k on: mods and such

    all, of course with proper warm up and cool down time before each "run" and with oil and filter changes every 3 k miles. at 6k swap to full synth oil.
    so what oil should i use for the first oil change??
