Just switched to PP @ 42000 on a Nissan Titan. Used Mobile Clean 5000 on 2 previous oci's @ 3000 miles. All previous changes done by dealer @ 3000 to 4000 oci. Wanting to do 5000+ in future or twice a year with the PP. Should I do a short oci on this change or just run it to the fall eg. Oct. or Nov.? I average about 11000 miles a year on this truck.
