I just took the oil injector pump off of my sons Blaster and drained the Yamalube 2-S out of the tank. I don't have a 2-S bottle handy and was wondering if anyone that had a bottle could look on the back for pre-mix directions. I'm going to run Yamalube 2-R now that I have the pump off, but wanted to use up the 2-S that was in the tank. I don't know if you can mix 2-S at a true 32:1 since the viscosity is so light compared to 2-R? Any help or thoughts are appreciated.

Thanks in advance!

PS...It's 40 miles to the nearest Yamaha dealer from here otherwise I'd just ask them when I pick up some 2-R.

 

If anyone does a search and finds this later...I called three Yamaha dealers and got the same answer...32:1 is fine to mix 2-S...40:1 for 2-R in a Blaster. I think I'll go with 32:1 and 2-R when he goes to the dunes.

 

if i were you i would run Amsoil Dominator in it... www.motosynthetics.com

 

Ouch....at $9 a quart + shipping that Dominator oil should work pretty well.....but well enough overall to justify spending 3X the $ on 2 cycle oil between top end rebuilds, on apparantly a recreational blaster? Not a chance. Yep.....4oz per gallon will be just fine and will still give long engine life with the 2-S. Just because there are higher priced 2 stroke oils available does not mean the 2-S should be disregarded as far as protection goes.
