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?
I wait for the revs to drop back down to normal idling range. The car’s hvac won’t put out heat but the engine is good to drive.
Same here…let the high idle die down a bit and start moving. It’s going to warm up faster (and produce fewer emissions) with a load on the engine and you’re not going to be wasting fuel.
