Make sure you use 2-stroke oil specifically for air cooled engines.

It depends greatly on the oil. There are several "smokeless" oils on the market now for outdoor power equipment, that are "one mix" for all engines. Some are better than others. I have been using Interlube's Optimol 2 cycle mix in all my engines, two AND four stroke for several years, and recommending it to my two cycle customers for even longer. I started using Optimol in my two strokes when it was first introduced in the US. Back then, they would extend the original warranty by 50% if you ran only their oil from day one in an engine. Due to the vagaries of mixtures and carburetor mis-adjustments, they no longer extend the 2 stroke warranty, but I still use and recommend the oil as it is virtually smokeless from the first pull of the engine. At home I use it in all my engines because I don't use more than a gallon or two of gas all summer long, and depending on the snow fall amounts, maybe another gallon all winter. By using it in everything, I only need one gas can in the garage, and can never end up putting straight gas in a two stroke engine by accident. The oil doesn't hurt my four stroke engines at all, in fact, it helped free up a sticky intake valve in my chipper / shredder that I was too lazy to take apart. And since many newer two cycles now have catalytic converters, it has to be formulated to not harm them anyway. I do mix it a little more oil than recommended though. I mix it at 64:1, or one "pouch" (1.8 oz.) to 0.9 gal (US) 89 octane unleaded gas. The manufacturer recommends up to 100:1, but I keep my two strokes running a little lean for performance, and the extra oil keeps me from having heat seizure issues. I also always recommend my customers do the same 0.9 gal mix, as I cannot know what their carburetor settings may be.
Optimol is also sold as Sten's Mix, and Snapper / Simplicity and comes in "pillow packs", sealed plastic pouches that look like a miniature body pillow.
For Poulan, Echo, Stihl, or other saw manufacturer oil, I would run that at the mix labeled on the bottle (except Homelite or the new McCulloch, these I would only use in their products).
