  Six months on mine, going for a year. Got a deal at AZ or I wouldn't have tried it. Glad I did though.

  Thanks all for the replys!.. Just bought a new(ish) 2017 Jeep Patriot with 9,700 miles on her and I'll be using 5W20 STP SYN Full Synthetic oil with the STP Extended Life filter... Been hearing good things about both.

  This may not apply to spin-ons, but the cartridge filters I see at the local AutoZone look very much like Chinese Frams in their two lower price levels, and like a Purolator at their top level.

  The previous AZ STP XL was made in S Korea by Daewha and had an ISO rating of 99%>20um. Though regular price compared to equivalent tier filters like FU was/is higher, post use anecdotes posted here of them looked good. No popular 7317 application either. Seemed best purchased as part of AZ oil/filter promo. Newest XL on AZ shelves now have China coo, efficiency rating is no longer on box. Not sure who's making them now.

  During one of Auto Zone's fairly recent oil & filter specials, some time after Christmas, I picked up Mobil 1 and the STP XL 16 oil filter. That STP oil filter was made in the USA. The recent Auto Zone oil & filter special was a better deal, it was Mobil 1 and a Mobil 1 oil filter for less than the previous Mobil 1 oil and STP oil filter. Whimsey

  Are you sure it was/is the XL (Extended Life) and not the newer STP MaxLife (ML)? The latter is made in the US by M&H Purolator. Haven't seen a made in the US AZ STP XL, at least in this area.

  My bad, You're right, sorry. The filter is a "Maximum Life" oil filter, S16ML. It says "engineered to last up to 15,000 miles", that fooled me. What is the difference between STP ML and XL oil filters? Thanks, Whimsey

  Just an FYI...both the XL and the MaxLife lines have multiple suppliers now. You'll see differences at the store level as certain suppliers are covering certain areas. The MaxLife product will no longer be produced by MH. As the current stock runs out...you'll see changes at AZ across the board on the STP product including the STP Blue line. Big difference between XL and MaxLife construction is XL is a blend media while MaxLife is 100% synthetic. XL is rated for 10k miles vs. 15k for MaxLife...whatever that means...like most marketing claims in my opinion...not much. It will drive price though!

  Is extended life oil filter worth it?

  If you have a vehicle that undergoes prolonged oil change intervals, an extended life oil filter is a good idea. Spending a little more on your filter will save you both time and money in the long run, while also protecting your engine more efficiently.
