I was just at O'Reilleys and they had the Mobil Super Synthetic on sale for $3.49/qt, They had 0w-20 and I read the package and noticed it states it only meets requirements for Honda and Toyota whereas the M1 0w-20 meets Ford and Chrysler requirements as well. Why would the super synthetic not work in a Ford application. I run M1 0w-20 on my Mazda 6 and would love to run the super syn instead to save $$ every oil change.
