Another thing that recently occurred to me, is Batteries.
Johnson Controls still makes all it's car batteries here in the USA. Most of the manufacturing is done in Illinois. They make the batteries that are branded Motorcraft, Duralast, EverStart, and DieHard among others.
If you have a choce between a Motorcraft or a Duralast, and the cold cranking hours are the same, pick the cheaper one. Inside the plastic, they re both the same battery.
