Is this oil ok??

What do you guys think? Just need to top off each motor and at the time this is what is available. Most of what I can find online says it is fine.

I asked this before and was told no.

That's fine. Why wouldn't it be?

I would say definitely fine for topping off!
Not the dedicated Yamaha oil for these boats if you are a stickler, or during break-in.

Something about the 4m should be a 4w.
Everything I’m reading says it’s about revs but should be fine for topping off

Here's a list on the back of a Yamaha oil changing kit if this helps any.
