> Napa now has a “premium” oil filter. Who makes it? (Wix makes the “gold”, which is what I use, and won’t ‘step up’ to premium, just curious. My guess is it’s a Mobil 1)

Off topic, but we offer five filters now:

\*ProSelect: For the cheap ass guy/girl or the junk ass car  
\*Silver: Better than ProSelect but still nothing to write home about. If you dont wanna be the guy who buys “cheap” but are still a Hebrew, you buy this.  
\*NASCAR: Special spin-flow technology but same filtering element as Silver.  
\*Gold: 40-50% more filtering element than the ProSelect and anti-drainback valve where applicable.  
\*Platinum: Designed for extended length synthetic oil changes; 5k-7.5k miles (Amsoil, Royal Purple etc. Oils)

Platinum & NASCAR are only offered as Oil filters. Silver is Air & Oil. ProSelect and Gold are Air, Oil & Fuel filters.
