New gasoline blends, since 2006 in CA and since 2009 in other states, can contain up to 15% ethanol and other substances, as a clean air additive. This is mandated by the EPA and these fuels have a shelf life of 30-60 days. They are very corrosive to engine and carb parts, especially alloys found in lightweight components.
You cannot mix or blend these additives away, once they go past their shelf life, you have nothing more than a brush fire starter...and while we are on that subject, do not ever dump, pour, burn or otherwise crap in your nest (planet earth).
There are legal and free disposal sites in most areas and the reason we have the government acting like a big nanny is that too many people don't get that a gallon of gasoline can ruin a million gallons of river, stream, lake or ocean.
The chemicals now used in our fuel are not easily absorbed naturally and they are pretty much non-combustible after 30-60 days. These new blends cannot even be transported by pipeline, they are too corrosive.
I've re-built enough of my stored chainsaws and brush cutters to know this the hard way. Using Sta-bil or some other ingredient AS SOON AS YOU BUY THE FUEL helps, but no amount of blending or mixing is going to make spoiled fuel work again.
