Who warms their vehicle up when it isn’t negative temps? That is a complete waste of time and gas. Well where I live it gets to minus 40 every year and averages around -20 all winter. That’s what warming up an engine means to me, not at plus 2. So yes I guess your right at the temps your talking about it’s fine to drive to warm up your vehicle but not in the winters where I live.

Ok you start your engine at -40 then drive it instantly and see how long you engine last. While your driving your running at a much higher RPM then idling. All that extra wear will cause premature engine issues. You do what ever you want. I will continue to warm up my engine before I put them under load.

Not when it’s cold. Oil doesn’t pump properly when it’s thick. Even when your driving easy your RPM are still well above idle RPM. I don’t know where you’re reading that from but as a mechanic I can assure you that it’s wrong. With the oil technology further advancing it getting better but it’s still hard on engines.

You’re going to wreck your engine. Oil is very thick as cold temps and it doesn’t lubricate properly because it can’t be pumped as efficiently. Wait the extra 10-15 minutes unless you like replacing engines.

The engine has to warm up. And driving isn’t the best way to do that. Oil gets very thick in really cold temps and doesn’t lubricate properly. Your car might start and run but your probably doing damage to you engine.
