Now this is only personal observation. I am no scientist, and certainly have not the hours or posts logged on this site, as some of the much more knowledgeable here. Just wondering if others have thoughts or input.
I have had my Prius Prime for 4.5 years. It's a 2018. I let the dealership take care of the maintenance. It had very low mileage in those three years, and received three oil changes once yearly. At year three I found this place, and some youtubers. I realized I wanted and should (IMO) change the oil every 6 months. I also came to this conclusion having my 6 month oil in usage from year 3 to 3.5 tested. It has high fuel dilution from the lack of use, and the way the hybrids warm up. Also the EV range on the Prime means the engine was used even less than a normal hybrid. In all those 5 oil changes I have used either dealer installed, or installed by myself OEM Oil Filters from Toyota.
Well 6 months passed from the my year 4 dealer oil change in June, so I changed my Oil. Tried Amsoil SS 0w-20 and an Amsoil EA15K09 (and yes I know it's a Fram endurance (by Champion)and I could have had it cheaper. I bought it before the FE was for sale). I wanted to try a different variety than TGMO. If it was cheaper to get in Canada I'd have also considered HPL.
Now if you read all that, and you're wondering why this is in the Oil Filter section we're there!
I have multiple neighbours that have Toyota's as well. A 2019 RAV4, is a couple houses below me, an HRV across the street, and a 2020ish looking corolla. They all use the same OEM YZZN1 oil filter. Not 100% sure on the HRV however.
One thing WE ALL SHARE in common. They ALL have a rattle at cold startup more often than not, especially after sitting all night.
I surmise the ADBV on the YZZN1 isn't a perfect seal and allows oil to slowly drain back down through the oil filter. I came to this hypothesis after using my Prime for a month roughly since the oil change. In that time with the Amsoil (Champion) EA15k09. I have heard a total of ZERO engine rattles on startup no matter if I haven't used the engine in days. I think the after market filter is attaining a more solid ADBV seal.
Anyone else noticed anything similar on their Toyotas, or anything similar in general? Or any reasons why I must be patently wrong, and the filter has nothing to do with the equation? Input appreciated.
