Just emptied (into my truck) a couple gallons of about 5 month old mixed gas
and it looked good and didn't smell varnished. Did the manufacturers do
something to 2 stroke oil to keep the mix from souring? I use name brand
oil, whatever Walmart has on the shelf in gallon jugs. I think it's
Pennzoil.
I've always gone by the dump it after 60 day rule.
