Yamalube Substitute?

I always used Quicksilver in my 90 Yamaha with no problems

Just the traditional 2 cycle outboard oil that quicksilver makes?

Yes, you don't need to use anything fancy in that motor.

I use quicksilver.
Dont know how true it is but someone told me that you should always stick to the same "color oil" . you can change the color but only if youpretty much empty out the oil tank. I've never stuck to the rule. I'm guessing the color hasxto do with the chemical makeup.

I have run pennzoil synthetic blend in my Yamaha 2 stroke for the last 200 gallons of fuel. That's equal to about 70 ish hours of run time. I use a little startron if my boat is going to sit for more than a week or two.

Never a single issue. One easy pull and it starts right up, even when it's cold. No issues with excess smoke.

I think frequency of use is more important that oil brand.

Any kind is fine. I have used the wall mart brand super tech for years is has the marine association aproved logo on it. $12 a gallon. TW3.

Penzoil Premium Plus, a synthetic blend. Can get it most anywhere for $20/gallon.

If you can find it, Mystic makes great 2-stroke oils. I've used their synthetic PWC oil in my old Kawasaki with great results. Their outboard oil runs very clean.
