I am convinced that the chemistry of gasoline has changed quite a bit. My nose suggests there is much more toluene (and of course ethanol) in it than ever before. As it gets old (a few months, not years) it gets sticky, fouling a lot of fuel filters and carbs. I think old gas is responsible for some of the sticky valve problems we are seeing. And then it is much more destructive to rubber gas lines, fuel pump diaphrams and all small engine fuel systems.
Old, I think you are correct...this isn't the gasoline we used quite reliably for decades. If you look up the chemistry of gasoline, there is no chemical definition or formula. The refinerys can mix a bunch of volatile waste products together and sell it for high prices. So their profits are at record highs, and their competition from smaller refineries is gone. They own the market, and we get toxic crap.
Rant temporarily over...until I have to fix another engine having bad gas problems.
