Oil Change Time

OK I am getting ready to do my pre summer oil change. In the past I have run Mobil 1 5w40. I am thinking of running the Mobil 1 10w40 due to the weather here in South Carolina. Any thoughts or issues I might be missing. As always, thannks in advance.

The manual for my 92 recommends 10/30 for temps from 0 degrees up.

I would go with which ever was cheaper bc there is very little difference between them
If the same price just go with what the manual says

Switching to 10W-anything from 5W-same will only cause more wear at startup. You want the least-thick oil at startup as possible.

Here's some good reading for you:
