No, unfortunately, I don't know what the difference in blends are. I
just know they use a formulation in the winter than allows easier
starting in subzero weather. I think the blend has a higher RVP so that
it is more volatile at low temps, but I don't know what the chemistry of
the winter blend is or summer blend either.

Not sure of the blend. Mine jumped after 5K bu it was still the same
"season" (winter). We have now switched to a Summer blend but I am still
getting the same mileage
