You do realize you're not supposed to blend different brands of oils right? Each company has a different mixture of detergent and oil bases used in their final product. Mobil 1 would have a certain mixture designed for just that oil. Royal Purple has certain detergents designed to work with just that oil.
Mixing different brands could lead to negative effects that will cost you money down the road. Just mixing RP 10w40 with RP 10w30 isn't an issue. Royal Purple has certain additives and detergents unique to the brand. Mixing RP and RP won't pose any problems.
As far as RP in a Versa? Sure, it won't hurt, but it's a little overkill. RP is a synthetic designed for high performance engines. You should be fine with a synthetic blend or a synthetic from Castrol or one of the "other" synthetics.
