I think it's because the different fuels have different burn characteristics/ energy output so of course they will burn differently. Your saw cannot automatically adjust between two different fuels so you need to tune them for the fuel you run and stick with it. This is why I never use anybody...
If you're only using small quantities it is fine. I burn a couple gallons of mix per week so I'm not paying the price for premix. If a gallon of mix will last you a few months then by all means use the premix stuff and save yourself the headaches of old fuel.
