I'm a bit wary of whether sticking an aim-n-flame in a pool of gas is a valid way to test anything. The corrosion test and the run-the-generator test is more interesting.
I'm not sure why you'd put two stroke oil in a four stroke generator and expect anything meaningful out of the test.
I love the mystery oil test. My grandmother swore by that stuff, and I thought she was making it up. Mystery oil? As a teenager, I inherited her car. Poking around the autoparts store I found the stuff really did exist, and had to give it a try. At least it had a nice minty scent.
