Would changing to a 0w20 oil help the solution? Or is it irrelevant to the problem? I just got my 05 3.0 and I wanted to know how to tell if it has the new insulated part, or if I should have it changed before winter sets in. I've also seen some electric heating blankets for engine bays, was wondering if these would help if I put them on an hour before heading out.
