*2 on the 5w40.

I used to live in the mountains of central new york. Weather was regularly single digits or below zero.

If you have access to a garage, do the following:

1. Get 5w40 in that poor girl. I'd just do a full oil change.
2. Make sure you have a fully functioning glow plug system
3. Do a valve adjustment.

I used to do a valve adjustment and oil change switch to 5w40 yearly every Thanksgiving to prep it for the cold. One year I forgot and the engine was hard to start every now and then when it got close to 0*.

Around March I would switch back to 15w40.
