He's making a joke that he's combining 1L of dino-oil with 2L of full synthetic shown in picture which comes out to be "semi-synthetic".

Ah, I hadn't zoomed in on the picture. 😆

Got a picture and/or part number?

one of them is probably for the oil filler cap. The other? Need more info... it might also be for a different model’s oil filler cap if Yamaha specs the kit for multiple models.

One is for the filler cap, the other is a metal crush washer for the drain plug.

I've never seen Yamaha branded 10W-40 synthetic in the US.  All I see is 15W-50.

I did my first two oil changes with Yamaha kits, later switched to Amsoil synthetic.  Zero appreciable difference in engine or transmission behavior between them.  However, I'm lazy sometimes don't immediately change oil when I take bike out of winter storage.  Synthetic seems to come out a little nicer looking after winter storage than mineral.

 

I find a person quoting a dealer as a reliable source of knowledge pretty hilarious...

Still on this topic... the Yamaha websites now show fill synthetic 10w40 oil change kits for the 21 Tracer 9 but semi for the previous gen .  Weird.
