I live in central Canada, and temperatures reach as low as -30C. Just this week, it’ll be -20C overnight and I always park my car outside. From what people have told me I should idle for 10 minutes when it’s extremely cold, and then drive off. What should I really be doing?
Depends if the car is carbureted or fuel injected. If it’s carbureted, then yes let it warm up and get up to operating temperature and adjust the choke as needed, if it’s fuel injected, you can drive off as soon as you start it, as long as the windscreen isn’t iced over then it might be smart to let it defrost for a few mins but even then 10 mins sounds excessive
