So what is your number? As I mentioned, AZ has my number in STP. Delco or MotorCraft are often available at reasonable prices. Also check Value Craft, Total Grip, and Power FLO. I would watch Purolator carefully. I never have liked their dome end bypass. Now they are owned by Botch, who knows. Of course, Botch could upgrade all the brands Purolator sells to the Motorcraft design.
If Champ is losing the Wal-Mart account, they may be aggressive about getting into other places.
Don't suppose protesting to Wal-Mart will do much good. Still many Frams are foreign made, and Filter Guy claims the Mexican made Champs are no more. ''Where is my @#$%^*&^%#$% American made filter?'' I ALWAYS buy American where there is a good option like the Champ filters.
