Can I tell if oil has already been added to gasoline?

Is there a way to tell if I have already added the oil into the gas can for my two-stroke trimmer?

Breaking out my the Stihl trimmer for the season and I found a 2 gallon gas container, full - sweet! But I realize I have no idea if I have already added the oil to the mix. (My gut says probably not, but then I was surprised to find a full gas can in my garage.)
Is there some distinctive odor or appearance that will indicate whether the gas in this container has already had oil added?
My gut instinct is that it's almost certainly better to run it with too much oil than too little. If I add another premeasured container, I potentially make a 50:1 mix into a 25:1 mix, with the caveat that but 25:1 is far better than 0:1. But is too much oil just as disastrous as too little?
In that case, maybe it's best to not assume anything and start from scratch - $300 trimmer vs. $6 worth of gasoline... (Say, did I just answer my own question?)
If that's the case, then my followup question is, how do I dispose of the gasoline currently in the can in order to refill and add new oil?
