A/C off until engine warms up.

Unnecessary. But waiting to hit the button for 20-30 seconds as the oil pressure builds is always a good idea, as is not racing the engine during the same interval.

I never fight here at FR, but I'm ready to go down swinging on this one.. No one can tell me that heavy A/C use does not shorten an engine's survival. Horsepower is degraded when A/C is on because A/C is a 'drag' on the engine. An engine has to work harder when A/C is on, versus when it's not in use. TRY IT YOURSELF, from a dead stop with A/C on, versus A/C off. You can't tell me that A/C isn't a drag on an engine. I'll get back to you when I hit the 300,000 mile mark on my 1.8T engine. I DO use A/C, but very very sparingly.. /snicker spit.

Don't EVER race with your A/C on! You might as well throw your white hanky out the window! You here at FR are all my brothers, but go ahead.. Try and 'dog house' me on this one.
