Can't find where I read it, but Chevron doesn't recommend Techron Concentrate Plus for 2-cycle engines, instead they recommend the 2-cycle formulated version of Techron, Ring-Free.
JMO, If you ran it very diluted, an additional 10x from the concentrated dilution (1 oz. Gallon), I don't think it would do any harm, as that's the level that's present in their pump gas. I suspect that the concentrated dilution keeps the 2-cycle oil from doing its job of lubricated the engine.
