Ed,

I no longer can find the source, but this = oil was reportedly produced by PENNZOIL for Wall-Mart.

If you were doing the 50-50 MMO= at the time, that could make a difference.  It contains both toluene = and xylene which are very combustible. Some 2-stroke oils contain other oct= ane enhancers.  The Super-Tech is 'pre-diluted' ("with what"? you may = ask) to make it mix more readily with fuel.
