What part of Missouri did you move to? Check out the Heartland threads to see what may be going on.

Myself, I run Rotella 15-40 in everything except the engines that require synthetic.
Being that it is garaged, I would think 5-30 would be a little thin for a engines of those years.

Hopefully HRL will give us his thoughts!
