Use of 0W40 oil in engine that calls for 5W30 -Bad or good idea?

I agree that it is over kill. Sure, $26 for 5 quarts at Wally World may be cheap, but what do you think the least expensive API certified 5w30 oil which is more then adaquate for your trucks, will cost ? Like, $14 for 5 quarts !
I would like to save $12 for every oil change for no appreciable difference IMHO in performance. Too much thinking time…save a buck or twelve and go with mineral 5w30.
