quote:Patman, Here in Minnesota where I live, about 6 years back the actual temperature was -54(F) below zero. In the winter it is not unusual to have -30 and -40 below with highs of -10 to 0. And this can go on from January through early March. It is nice to have an oil that will allow easy starting on these mornings. I do have a garage, but not everyone here does. 0W30 is not overkill, it is an oil (Amsoil or Mobil 1) that successfully works in a very broad temperature range (super sub zero to hot and humid), I know because the proof is in my engine (224,000, 3.1 v6, runs great). Good Day, Steven
