Re: 100:1 Mix
If you have an ace or a true value try there, if not napa sometimes will sell something called sten mix which is re-packaged opti-2. The most important thing to understand about opti-2 is how it behave in a 2 stroke engine differently than other oils. There is an additive (I believe it is boron based) that smooths surfaces in the engine to a microscopic finish. When compared to factory fresh cylinders, and cylinders run on conventional 2 smoke oil, the opti-2 is the smoothest by far. I have run it in all of my 2 strokes including my chinagirls and I can say for certain that everything that has gone wrong on my engines so far has been due to vibration and poor construction but NEVER oil failure. If you use opti 2 you WILL like it!
