As I posted earlier in week, the new Mobil1 oil filter appears to be made by Purolator and resembles the Pure one in construction and materials.
You may find that relatively easy locally.
Otherwise, KN, RP and Amsoil filters are all same manufacturer with slight differences. You'll pay more for those vs Puro or M1. All good choices.
