The coldest it gets where I live is the low 30s rarely (that’s Farenheit for all you outside the US—near freezing), so I don’t have much experience with cold weather driving. I have heard, however, that it’s always a good idea to let the car run for about 30 seconds before pressing on the gas. When the engine is not running, there is no oil pressure, so all the oil drains out of the block into the oilpan. It takes a few seconds for the oil to start circulating back into the engine at startup, so giving your engine the time to allow this to happen before getting your RPM’s up saves lots of wear and tear.
