You should short-shift until the oil is properly warm. You can still match the performance of most other cars on the twisties whilst you've got a cold engine if you can preserve your speed around corners whilst short-shifting.Bing said:So I know this is the ///M section, and I don't have the same engine, and I don't have actual temperatures on my low-end dials... But I try to keep below 3,000 RPM until my temp gauge gets to it's normal (vertical) position. Is this simply a wise thing to do with any Z, or am I being overly careful of my car ?
