This NPS comes off an older neighbor lady 2004 Honda Civic LX with just over 70k original miles. I can only guesstimate the miles based on the indy shop's window sticker. Pretty sure they go by 3k mi. oci so, between 5-5.5k miles on whatever bulk oil shop uses. When I've cut open NPS before, they were Wix based with nitrile adbv and coil compression spring. This one obviously Purolator 'type' construction, but Wix has been moving in that direction. I was very surprised to see the NPS with a silicone adbv, nice. Be interesting to know if made at Puro plant in Fayetteville, or Wix plant in Gastonia. With M&H, no telling. But this specific NPS jobber, very respectable. Super Tech 10k Full Synthetic 5w20 and Super Tech MP7317 oil filter went back.
