I use 5w30 like normal and was going to use 5w40 cause higher Milage , she got 5w20 oil

Will this hurt my engine swapping like that to a lighter oil??
P.s anything bad will be used for further disagreements against her

Consider yourself lucky that your gf will have anything to do with cars! Don't hold it against her, ever.
