Hi All,

Simple question, I don't drive my Turbo much in the winter. However, when I do, and it's decently cold out, should I let it warm up a bit before taking off? I'm asking because I know in many BMWs they say to just get moving and not wait for the car to warm up a bit.

Thanks,

On a modern fuel injected engine in cold weather (with the correct oil), a minute or two of idle is more than enough, just keep the rpms low and the shifts slow while it is fully warming up.

No banging into the rev limiter until everything is *completely* up to temp :-)

maybe a minute or so, then drive off. keep the revs no higher than 3k until the engine oil and coolant are warm.

Yes, and tranny needs to warm up too.

manual says "no warm up necessary, but not over 3k rpm until full 'op temp" has been reached. it's a ( once ) high end german porsche. start and drive.

how cold are your winter temps?

Idling a car is no good. Start and drive off.

Once the the engine smooths out (not more than a few seconds) after starting, you can drive off. I like to describe the action of the initial cold drive as putting the car in limp mode. Just go easy and watch the tach reving no more than 2.5K. This will take less time in warming up your car. Letting it idle in a long period of time is not recommended because of the rich fuel it dumps and thus thinning out the motor oil.

In my Alfa, I'm actually supposed to let the car idle to warm it up - even when it's relatively warm out. Most Italian cars, especially older ones, have small oil passages so it takes a bit of time for oil to flow through.
