The OE series is fairly recent and is comparable and in many cases better in price than the more popular brands. About $4.40 less for a qt of OE than the 1 year Signature oil. No special filter either and since it's designed for changes per the owner manual, it seems to be more suited to the typical consumer who is more comfortable with the 6k change. Motorcycle still up there at just under $12 a qt.
