Re: The best thing I have ever done for my HT...
As mentioned its not sold retail rather by the instantly untrustworthy multi-level marketing. Try Google and find a dealer near you. They have a 2-stroke specific product and gas conditioner which I am using. Both have the polarised oil of different grades, the stuff in the conditioner is thin grade so will penetrate deep into the metal pores while the 2-stroke additive is more viscous.
The reason I took the risk and tried it is because there are no strange additives like other snake-oil additives so I figured it will either be placebo oil and not hurt my engine or it will work.
