M1-103A for the 2023 Prius. Made in Vietnam. The construction looks to be far better than any Fram. The center tube has round holes as opposed to louvers. Let me know if I've missed anything in terms of filter discussions.
The 2023 Prius is sitting at 51.2K miles or 4K miles more than when we bought it. The oil looked absolutely pristine at that time and the dealer said that they had changed it but did not specify the mileage. This filter and 0w-16 HPL Premium Plus are going in soon. There are no plans for a UOA as I have no idea of what oil is in there or the actual mileage. Perhaps I will pull a sample at 10K but that won't be until next March at the current rate of accumulation.
