Nov 22, 2004 · I've used STP oil filters for a while now. Part of it is due to convenience- when I'm at Autozone buying Mobil 1 I can take two steps over and grab an STP filter. I have used them on both my 91 Nissan 240SX and my 95 Camaro Z/28 (although I think when I get my Camaro rebuilt and back on the road I'll switch it to ACdelco).

Nov 30, 2013 · Been purchasing the Autozone discounted bundled deal for a 5qt container of oil of your choice plus an STP filter. Filters have been fine so far and has been the best pricing for M1 ESP 0W30 plus filter that I can find so far for both, when purchasing oil and filter together.

Jul 23, 2008 · Recently purchased an STP engine air filter and when I compared it to my OEM, it was of poor quality, so I returned it.
