2007 DTS Lux II, 2009 Escalade 6.2L.
I know this might be beaten to death. But the reason I’m asking is not if it is bad or good. I want to know why they say it’s not good to do. Now it’s also been said that is hurts the engine, how? In my mind using just common sense, any liquid via petroleum will slightly thicken as the temperature drops I’m talking New England weather here. Wouldn’t it make sense to run the engine for 5-10 minutes before puttin load on a very cold motor? My rule of thumb is 10 minutes and then I take off. Anybody on this?
