I usually get 5w-30 mobil 1 synthetic motor oil at sams club or costco by the case. Now that oil change time is around the corner, I went to both stores and they have only 10w-30. Any big diferrence between 5w-30 and 10w-30. I live in the snow belt

is it still snowy? 10-30 is ok

I'm pretty sure my manual said to use 0w-30, isn't that a little thin? just seems like it could be a typo to me

WJM

if you are in temps above 80 regularly that may get burnt up quickly, aka you will add more quarts

0w-30 Absolutely correct.

Is 5w-30 alright for the summer??? And is it ok for highway driving???
