I live in a climate where the summers are in the 90's and the winters are in the 20's. Should I change oil weight depending on the season and if I do, which weight for summer and which for winter?

I currently use 10W-30 Mobil 1 Synthetic.

This was really only an issue when they used to run straight weight oil like 30w and 50w back in the day...

With new oils don't worry about it, unless you live in an area with extreme heat/cold

 

If I did live in an area with extreme temperature differences what would I want to use per change in seasons?

 

I work at Jiffy Lube and we get this ? all the time. 10w-30 in the summer and 5w-30 in the winter. I live in New England so i know how you feel. I actually use the new Mobil 1 0w-20 now for my civic. It says right on the bottle "made for Fords and Hondas"
