This may sound silly but.....

How do I know if I mixed my gas and oil? I usually run a 50:50 mix of VP C12 and ethanol free pump and 927 at 32:1. I brew this up in my fuel jug leaving the rest of the VP (2 1/2 gallons) in the 5 gallon can for the next time I fill up. The chanceability I already mixed this while drinking beers in the garage is 50:50. I grenaded my bike and haven't ridden in a few months so I was going to mix up some new fuel with the 2 1/5 gallons I still have in my VP can.....but I can't remember if I already mixed it or not.
