I have used 2 cycle oil in my cars, van, with tcw3. Great cleaner and upper cylinder lube too. One oz of the 2 cycle oil to 5 gallons of gas in the car, runs great.
In an older 2 cycle boat engine over the years, just about any good brand name 2cycle oil worked, no complaints....growing up in the 50's, Dad poured one quart of 30 wgt oil into a 6 gallon tank and our old Johnson 15hp ran forever,,,1958, never an issue..
