Syd: I suppose that there are as many recommendations as there are products. I started using Marvel Mystery Oil some 25 years ago adding four ounces to every ten gallons of gasoline. Later, a friend who was an outstanding mechanic sugggeted that two cycle engnie oil worked just as well as a fuel additive at a lower cost. That was about fifteen years ago. I have used two cycle engine oil at a rate of four ounces per ten gallons ever since. It has worked well in over 20,000 miles of driving mostly in the Series 33. Some two cycle oils tend to smoke a bit. Valnoline does not so that is what I use. The scale on the side of the quart bottles is very helpful in measuring the amount to be added.
