This is the first filter I've cut open from my Highlander. Got it used at 120K, it came with the proverbial stack of repair receipts an inch and a half thick, oil changes every 5K, primarily Toyota conventional, ACDelco Dexos, and then TGMO synthetic. I wasn't thinking that this engine had a lot of deposits, but before I go for 10K FCIs I just wanted to be sure. This filter was put on with PUP 5w20 from 128,622 to 136,675, from Sep 2020 through Feb 2021. It was replaced with Kirkland 0w20 and a Wix filter. Just as with the EG that I cut open earlier this morning, I was surprised at how supple, and light, the silicone ADBV was. The only other filter I've cut open was an ACDelco for the Camry in my sig, and the ADBV was nitrile, and nowhere near as supple. Marks on filter media in last pic were caused by me. I was thinking of cutting the media off from the wire backing, but it didn't budge so I decided to leave it alone.
