I just purchased some Valvoline Full Synthetic High Mileage at the Walmart Black Friday sale and now noticed Valvoline Full Synthetic Advanced at the store. Also shown is some Maxlife High Mileage from last year. The advertising department must be working overtime. Feel free to comment on the differences. ( beyond the obvious grade difference and high mileage aspect of the selected oil) Maxlife vs Full Synthetic vs F.S. Advanced.
