Have a Ford Fusion V6. use it for 30%city/70% highway miles. Ive been using Motorcraft Syn Blend/TropArtic syn blend 5 w 20. Thinking about upgrading to Full Synthetic. Usually change out twice a year at around 6,000 miles. I plan to use the Motorcraft fl820S Filter. Temperatures are below freezing to over 100. What extra benefits will I see if I upgrade other than I lighter wallet. I see Platinum/Ultra/Ultimate Durability/Mobile EP as readily available.
