Here's the absolute bottom line about pre-mix from a widely acclaimed authority (namely me). Yamalube 2-R mixed with 91-93 octane NON-ALCOHOL pump gas at a 32:1 gas to oil ratio.

Yep

[hodakamax]

Yep, I listen to authority and agree.

I have been currently using the Yamalube 2R. Prior to that I was using the 2S. I like the 2R better! Mixing it at 32:1 joe 4 Oz per gallon! Victor

Me too on the 32:1 2R. But I run avgas since I can't get ethanol free pump gas.

Also remember, Yamalube 2S is formulated for oil injection applications and 2R is for premix. Not interchangeable. 2R is too thick to run through oil injection pumps accurately. (That tidbit actually came from a real authority ). Just an anecdote here - one of my riding buds premixed with 2S at 32:1 in a pinch and with that, fouled plugs every 5 minutes.
