Oil brand/type, climate, load, jetting and the engine design itself makes more difference than the engine size in this case.
2.6 oz/gal is 50:1 - this would work with a broken in engine and a very good oil, but not necessarily low cost oil.
What brand is this Lowe's oil?
So ... what you are telling me is that a 70cc is actually 67cc...GOT THAT:-) so,im guessing the 80s are the same no? I simply want to know the correct mix so I dont have to guess anymore.
I am running the same type of chinese 2 stroke as most of the people here. Im not running 50/1 I run 32/1 because the guy that sold me the motor reccomended 30-35 after break in so I figure 32 is about right but that was specified for an 80 not a 70 are they the same motor? I wouldnt be surprised,ive been told they are.I dont know about this lowes oil,I dont trust anything that is a magic fix across the board,there is a reason for 32/1 and 4 0z/gal, if I cooked my motor with this oil on thier recommended mix you could bet they would be buying me a new one as thier misprinted bottle was being surgicaly removed from thier ummmm....shelf! LOL!
Thanx for the input,im still a bit confused Ill check the threads
