I see that most Napa's are running sales on both the Gold and Platinum series filters for $6.75 and $7.99 respectively (at least in my area). What is the general consensus on one vs the other these days? Looks like they both sport the silicone ADBV and the Gold has a long history as a quality unit made by Wix. Any news on the Platinum? Application would be truck in sig with OCI of 1yr/10k miles/IOLM indication, which ever comes first. Typically I change at <15% IOLM which is in the 8000-8500 mile range.
