If, if and if. Problem is if the 100 to 1 mix is off even a little leaner the engine will score. If the main jet mixture is leaned out, temperatures go up and the engine will score. If the cheapest low octane fuel is used detonation will occur. Particularly if the main jet is leaned out. Scored cylinders for sure then. When looking at the labels there are several types of "Two Stroke Oil". Some is for oil injection, some if for gas/oil mix, some is for cool running water-cooled outboards, some is for lawn mowers, some is for alcohol blend race engines and some is for snowmobiles with large cooling fins in cold weather Chain saws are the toughest to lube. The highest HP to cooling fin area in order to keep weight and size down. As previously stated use premium gasoline blended at 50 to 1 even if the jug says 100 to 1. As well, run that two stroke rich and tick off the EPA and the environmentalists. The rich mixture keeps combustion chamber temperatures hundreds of degrees cooler. Reading the label and using the proper two stroke oil never hurt either. Outboard oil in a chain saw is just looking for trouble.

you hit the nail right on the head. The reason there is a differance between outboard oils and chain saw oil for example is the ash content. outboard engines use a high ash content, chain saws and trimmer use a no/low ash oil. As for fuel, you need the purest, high octane fuel to properly run a 75:1 or 100:1 mix. with no alchohal at all. Regular 2 cycle chain saw/trimmer oil is cheaper than the Opti synthetic oil we have, so I do not see the use. The Redmax oil I sell, at a 50:1 mix does not smoke, runs very clean, and can be mixed at less than a $1.00 for a gallon of mixed fuel. One reason for smoking 2 cycles is using old gas or not running the engine at full RPM, it makes too much noise, but this is what causes carbon build up in muffler and ports, there is not enough heat to keep it burnt out.So, to add fuel to the fire, in my opinion, synthetic 2 cycle oil is a waste of money for what little good it does.
