I'm impressed that your wife knows what an oil filter is...let alone knows a brand! Mine wouldn't know where to look for the filter...OEM Toyota Denso YZZD3, Fram Ultra 3600,or Mobil 1 209 For the truck.
Usually a Fram Ultra for the car but my wife is an Alexander Rossi fan (Indycar) and insists on a Napa filter. So be it.
Subie, I agree with you 100%. I wouldn't use Wix filters if I couldn't get them on sale for 1/2 off.Mostly Fram with a mix of the PH9688 and the XG/TS9688. The last three runs have been on the extra guard's with 4k to 5k OCI's on syn blends. Never really buy the tough guards because the pricing for the 9688 doesn't make sense to when the ultra is something like $2 more and I don't run filters that long.
It's just hard to beat Fram's efficiency, availability and reliability for the price. Wix makes solid filters but with worse efficiency I don't see the benefit in spending $9 per filter for worse filtering over a 6k max OCI.
Napa Gold/Wix, and since there are 3 different parts chains within 5 miles of home, no backup.
