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?
10 minutes is way too long. Wait until the RPMs drop (choke is off) and you are good to go. Especially now when every car is using 0 or 5W weight oil.
