Warm-up Time
Hey there.
Wondering how long I should wait before driving away after the vehicle has been sitting overnight (in garage)?
Also - with winter just around the corner - do most people let their vehicles warm up to a certain temperature before taking off?
Thanks,
SparkyCanada

About as long as it takes you to put your seat belt on and shift into the right gear.
Ideling does nothing good for your car, environment or wallet. Start and go. Keep revs down until operating temps have been reached.

nope. not true. idling actually extends the time it takes to warm-up. as said I tend to keep RPM's below about 3000 until the oil temp gets up into the ~200 degree range, then I have no hesitation running it to redline.

The faster everything comes up to temp the better.
I start and go ......... now I do wait for the idle to stabilize -- that can take an extra few seconds in really cold weather and I don't gun it through the first shift since it is in 1st.
Now ..... everybody else in the family normally has it in gear before the starter has turned off and then I hear it scream for the first 100 yards.

How cold?
Zero farenheit? -10, -20, -30? When it is below 0, if you don't allow the engine to warm up a little, your breath will frost up the inside glass immediately and you will be driving blind...
There will be time for the tranny to warm up as you crawl along waiting for the flat spots on your tires to go away.

The Germans are **** when it comes to engine oil warm-up. They are more concerned about engine oil temperature than with coolant temps.
General rule of thumb is to start the car and let the idle control valve run the rpm at a slightly-higher-than-normal idle which may last anywhere from 15 to 60 seconds. Afterwards, drive off but try not to over-rev the engine until full warm-up occurs.

Completely agree with No HTwo O's suggestion. Ony my 997.2 I take it easy with revs until engine (not coolant) oil temps are above 175 degrees. Avoid short trips especially on cold winter months if you care about the engine.

From what I understand too, start up and drive conservatively once you can ambiently see and sit in the car. The synthetic oil was built to withstand these conditions above regular oil............it coasts much better.
Remember that old late night infomercial where they would drain the engine and let it keep running........and Mobil 1 never seized up.....

In subzero weather I make sure to warm her up for a while until I take off. Makes a big difference and gives the heater, heated seats and steering wheel time to get toasty! In good weather I wait for the initial high idle to stabilize then go. I don't think this habit of mine is bad, but correct me if I'm wrong.
