And why would that be? Are you suggesting that a Toyota cannot run on the same oil in Japan and Pennsylvania? I understand the question if posed as Japan vs Texas. That wasn't my use case.
For my wife's 2023 Camry hybrid I use Mobil 1 0w-16 and the OEM filter as they were on sale for $3.50 per at the dealer and I bought 10 of them. I also put a Fumoto valve on which I find to be so nice. I change the oil every 5k.
