"Idiot. 1 gallon of gasoline containing a few ounces of oil, mixed into a 15 or 20 gallon tank, once a blue moon, is NOT going to ruin the converter, or contribute anything meaningful in terms of pollution. If the guy's got many gallons of oil/gas mix, then he'd be wise to get rid of it a little at a time. But you knew that. You're really smart. "
You know the best part? Watching how your feeble mind works. Someone has a problem with a neighbors dog, you advocate poisoning it. Someone has a few gallons of left over 2 cycle fuel, you recommend putting into a car's gas tank where it will only add to pollution that we're all trying to eliminate. Both of these are classic examples of how your whacko mind operates. Everyone else would think of all kinds of reasonable solutions, yet you jump to the worst, and/or illegal ones. In the case of the left over 2 cycle fuel, it could simply be given to anyone who has two cycle lawn/garden eqptl, like a leaf blower. Ever hear of those, genius?
Maybe you should stick to giving advice on how to maintain lawns through benign neglect.
