I live in Toronto, it can get bitterly cold... I drive my car to work and back 2-3 times per week... I usually start my cars and leave them running outside for 7-15 mins before I drive them, but I don't know if I'm supposed to do this with the 911....

Might post this over on the 993 turbo forum.

You drive THAT to work in Toronto? During the winter?

Not sure if the turbo should be treated differently for warm up, but I don't go over 3K rpms until the oil temp is at least to the first line.

when I had a turbo, I let it idle after each drive for at least 2 minutes to cool down. I never worried about the warm up, just didn't HIT it until warm.

Cold oil is bad for every engine. The only difference for your tt is how much the incremental damage from that cold starting could cost you to repair eventually. Porsche certainly designs their engines to survive these conditions so it's probably not going to significantly shorten your engine life. I would still try to warm it up as much as possible before driving it. I always give mine a couple of minutes to warm up (and cool down) even here in relatively warm Oregon.

Do not have it sitting there idling. It's not reccomended by Porsche and it is not good for the engine. If you actually start then drive off, after a minute or so, you will find by turning on the heat in the car, you actually have heat after a 2 or so miles - good sign the engine is agetting nice an toasty. Our aircooled engines get very warm very fast. +1 on the keep it below 3K RPM before the temp. indicatator gets to the first line (or second line if you count off/dead cold as the first line). With a Turbo I would be more concerned about cooling down. In this case you do need 3-5 or more to let things cool off (unless you want to fry some eggs on your intercooler).

Are you Allen from simply tire? if so I spoke with you couple months ago when my broinlaw was buying tires from you and I directed you here to rennlist...welcome.
just drive it below 3k rpm until in normal temp range.
now put that car away till spring and get it ready for Mosport!

Cold oil will only "damage the engine" if it is the wrong grade (too heavy, hence flows too slowly) for the climate. So if the oil is designed for the temperature range of your climate, it will provide the same protection, regardless of a cold or hot climate. Refer to your owner's manual for choosing the right weight for your climate.

don't let the car idle,
just drive it gently till maxx 3000 rpm.
if you let it idle the oil pressure is at its lowest.


that is also when you brake in an just fresh engine at around 2000 rpm
(first start) it is minium rev with "maxium" oil squirt.

The owner's manual in my 964 says never to let the car idle to warm up. The best way to warm the car up, so that the oil is cold for the least amount of time, is to drive it gently for 5 min or so.

+1 on don't let the car idle, get in an drive, keep under 3k. On cold days, it takes the gear box in my car longer to warm up. The gear box is important too, you should be able to feel a difference of a cold and warm gear box.
