2 cycle oil

[Genofish]

Is Yama lube & Quicksilver equvilant? They both are a TC-W3

[YourBobersDown]

quicksilver is just mercurys brand of oil, but since yamaha used to make them both im sure they are close. I run amsoil in all of my stuff truck and boat, I will never go back to conventional oil.

They should both be fine for running in your motor.

I'd try and run as close to out as possible before switching over to minimize any issues, but you should be just fine.
