...that I spoke to said that if it's diluted with your car's gasoline, it would love it!

Silly Question!!!!

It just shows how ignorant americans are becoming!!!!!!! Dumping water into your tank is a bad thing. Dumping two-cycle oil into your tank doesn't hurt. I've done it a long time. Two-cycle oil is designed to burn well in an engine without fouling anything. Sure running a tank ful of 25:1 two cyle oil will smoke as it will in a two cycle . But look if you are starting with 50:1 and then dilute a couple of gallons into a tank full of say 20 gallons that oil is diluted to 500:1. No engine is so sensitive that it can detect 500:1 oil!!!! But I've ran staight 50:1 gas in my lawnmower after the 50:1 sat in the garage all winter with no ill effects. Again 2-cycle oil is designed to burn clean otherwise you would have to change the spark plugs too often. During the break in period my out board manual recommends 25:1 oil mix and it smokes more but no fouled plugs...at 25:1!!!!!!!!

Another Idea

As you can see from all the definitive answers below, the answer to your question remains cloudy. What I like to do when boating is to mix the approximate amount of gas/oil for the expected trip and also carry a spare can of unmixed gas and extra oil. Af the end of the boat trip add a little stabalizer in what remains in the mixed fuel before shuting outboard engine down, and later pour the unmixed gas into the auto. RK

I once had a car with a badly worn

engine that burned a quart of oil for each tank of gas. That thing laid down a fog of blue smoke everywhere I went. Ran it like that for two years before I finally got rid of it.

oil it

i used to put the leftover outboard fuel from the dink into my truck, but the truck was old and didn't have fuel injection or a catalytic converter.
