I have a 1 gallon "mixed gas" can and TRY to use it within a few weeks of mixing. I don't get *as worried* about it if I find Ethanol-free gasoline but get downright paranoid if I know I am mixing with ethanol-blended gas.
It is my belief that the Ethanol blended gas reacts differently with 2-cycle oils than straight gas does and I would not advise going leaner on the oil than 50:1 with blended gasolines because the ethanol already leans the air:fuel mixture some causing the engine to run hotter than with straight gas.
