Will two-stroke fuel ruin my lawnmower?

What would happen if I put gasoline with two-stroke oil in it into my conventional four-stroke lawnmower?

A while back, I borrowed a roto-tiller with a two-stroke engine. To fuel it, I mixed in a little bottle of two-stroke oil with gasoline a plastic gas can I had in the garage, the lid to which I lost a long time ago.
I tilled my rotos, and I've since given the roto-tiller back to its owner, who lives a considerable distance away and whom I don't often see.
I still have about a gallon and a half of gas/oil mix left over, in a container that has a piece of tinfoil and a rubber band for a lid, and I don't know what to do with it. Obviously I can't just dump it down the storm sewer, and I can't keep it in the garage because the can isn't airtight, so the garage fills up with fumes.
So I was thinking I'd just use it to run my lawnmower, a well-used cheapo Sears push mower with a Briggs & Stratton engine. What will the result be? A fouled plug? Nothing? A huge explosion?
Barring using this gas - which has an estimated value of $5.50 and would likely serve a summer's worth of lawn-mowing - how else could I properly dispose of it?
