Engine revs to 3000 rpm at start
Just wondering if this happens to anyone else...
When I first start my car in the morning the engine automatically revs to 3000 rpm. Of course this is really bad for the engine since there's no oil pressure yet. You can even hear a bit of rod knock! Luckily I use Mobil 1, but this is still not cool in my book.

i find it normal if i cold start, and immediately put it into gear, 3 secs, then clutch in, it'll go to 3k on it's own
flame me all u want for driving on a cold start, but time is money and i cant afford to wait even a minute,

My cold starts are 1,500 rpm and it's been pretty cold here in North Florida for the last week or so (upper 20's and low 30's in the a.m.). The rpm's gradually decrease to normal in about 1 - 2 minutes.

Oil pressure ramps very quickly, and remember, viscosity is thicker when cold.

Mine does the same thing 1500rpm on a cold start. Im in VA 20-30s on mornings lately. I don't even have to press the gas pedal to go, just let the clutch go slowly and there she goes. Once it warms up it is in the normal 700-800rpm idle.
