What is the highest QUALITY Mobil 1 30 weight - Mobil 1 Advanced Fuel Economy 0w30, 5w30, 5w30 Truck & Suv, 5w30 Extended, 10w30, 10w30 High mileage, or 10w30 Extended ? Which one has the most PAO ? Any one have analysis of each back to back ? I know Extended has 50% more "Super Syn" than regular & that Truck & Suv has a boosted level in between. What is "Super Syn"? I am in Sunny Florida where I rarely see any early morning temp below 40 during winter. It is going in a 4 cyl 16 valve [censored] engine with less than 20,000 miles. Thanks in advance for the replies.
