Is 10w 30 in my Mark going to be a problem?

[fonzieguy]

Well I went to a jiffy lube to change my oil this morning and they put in 10 w 30 instead of 5w 30, is this going to be a problem?
I live in Atlanta Georgia so it is hot I remember reading how 10 w 30 would be better in hot weather?
I really don't want to have to go back up there I'm trying to get a nap in before I have to drive to savannah.

Iam using 10W30 and it work good.

It will be OK. Ford actually now recommends switching to 5W-20 so put that in next time.

I think they only recommended the switch for gas mileage
