honestly, that is one of the worst things you can do for it. When you run an engine like that (especially in the colder winter months), all you are doing is giving the engine just enough time to warm up and create condensation inside the engine and exhaust. If you really think about it, there is no way that moisture can get out of the system, so it's just sitting there allowing everything to rust.
Also, do you think it's really worth having your car go though a cold weather start-up every week? It only takes a matter of hours for warm oil to completely drain back into a pan, but it takes much longer for cold oil to circulate though an entire system.
I'm not saying that I'm completely right, or you're completely wrong, but sometimes you have to step back and really think about things that you are doing.
Also, what weight oil are you running for those cold weather start-ups?
