Cold starting...

My SVX luckily starts in all weather conditions. From the 101 degree day in july in NYC, to the 3 degree (-25 with wind chill) last night. Runs the same in all conditions. Warms up in the same amount of time, although in sub zero temps, it seems to create a bit more vibration during the first minute of warming up. Temperature gauge always stays at the milimeter below the middle of the gauge when fully warmed up. Cool.

But I was wondering, since the engine idle jumps to almost 2k RPM right when you turn the key, and then settles to 1.5k while warming and slowing going lower, is warming up even nessassary anymore? Like, is it okay if I drive it immediately after I start it as long as I keep the revs below, say, 2,250 RPM until it's fully warmed up?

A friend told me NO NO NO NO NO!!! The oil isn't fully running through the engine yet, and that makes it metal to metal contact. But if the car hits 2k RPM right when it starts up, why can't I drive it softly? Wouldn't the spinking of RPMs while driving softly actually accelerate the oil flow safely?

Basically, what are all y'all routines for warming up your SVXs? Do you wait for it to be fully warm, or do you just start and drive? And is the "metal on metal" thing true, or just a myth fit only for older cars? Just want to know so I can keep my SvX running well for a good, long time...

Any input greatly appreciated.
