Here is my sample of Amsoil SS 0w-20, one year in service. 80% Hwy/20% city. MM light calls for oil change around 6000 miles (it assumes conventional 5w-20). This was with a Fram Ultra filter. This oil does a nice job with my one year interval but I have changed out to M1 EP 0w-20 with M1 filter simply due to it being 1/2 the cost. I do not plan on trying to go longer than a 1 year OCI. This time next year we will see how M1 EP compares.
