That's true, my last winter's UOA was with 10w30 Schaeffer oil, with my car parked outside all night long with no block heater used (I was too lazy to use it last year) and in a 4,400 mile interval here were the results:
Iron-25
Lead-7.8
Al-6.2
Copper-3.3
Chromium-1.3
Then I did a 4800 mile interval from April to June and got the following results
Iron-21
Lead-11
Al-5.8
Copper-3.5
Chromium-1.0
Both runs were using an AC Delco air filter and a K&N oil filter.
So my winter UOA wasn't much different than my summer UOA, so obviously my driving habits are ok.
Also keep in mind that for the first minute I don't even touch the gas, I'm basically idling along at less than 5mph, so it's kind of like idling with no load on it anyways, I'm just not wasting time in my driveway.
It ticks me off seeing my neighbor two doors down who idles her new Toyota Matrix for at least 5-10min every morning, even if it's above 32F in the early spring she still sticks to that habit. I also used to work with a lady who started her Honda Accord 20min before leaving work, and would stick with that habit for the first few weeks of spring, I even saw her doing it on a day that was almost 70 degrees!
