Got a brand new Yamaha outboard
The recommended oil is synthetic 10W-40 API SJ, SL
I have trouble finding a Mobil oil (Mobil is what I use for my cars, the bigger boat with inboard diesel engine etc.) fitting this spesification without API service class SM and SN as well. I understand that newer API service classes are backward compatible with previous classes. But why the heck do Yamaha put a SJ, SL spesification on a 2021 outboard? I am thinking there must be a reason and I dont want to come in conflict with the recommended oil spec on a brand new engine under warranty.
