My car has a 4qt capacity.
I'm currently using Mobil 1 High Mileage Full Synthetic with 7500K OCIs
my question is: would mixing 3qts of the High Mileage and 1qt of the Mobil 1 Extended Performance(with its 15K OCI claim) let me get a longer OCI , while still letting me get the benefits of a High Mileage oil?...i'm aiming for 10K OCI.
