I currently use Purolator P1 filters in my vehicles, and my OCI is at 6000 miles, should I be changing this filter at the recommended 3000 miles or keep them in until I change my oil? What would be a good alternative, Bosch Distance Plus filter? I'd like to get away with having to change the filter only when I change the oil. Any recommendations? Currently using Amsoil SSO, QSUD, and Pennzoil Ultra in my vehicles.
