I'm not sure how the results of using 2 stroke oil in gasoline engines is going to be quantified. Use in diesel fuel is well tested, and TC-W3 is so-so as a lubricity additive, but what on earth would the benefit be in gasoline engines? It will likely reduce octane, and at the low levels being tested, the very low lubricity of gasoline is likely not affected (not that extra lubricity is necessary).
Post results. I am curious to read more than anecdotes about smoother idling, you know to save fuel you should not be idling much anyway, right?
