Is 2-cycle air-cooled engine oil the same as 2-cycle ashless oil?

I use the ashless oil in my Lawn-Boy mower. Can I use the same oil in my Weedeater FeatherLite Plus? It calls for 2-cycle air-cooled engine oil.Is 2-cycle air-cooled engine oil the same as 2-cycle ashless oil?
All 2-cycle oil is the same. Brand names have different gimmicks to intise you to buy their product. I use the same gas oil mix in my Weedeater chainsaw and leaf blower. 4oz to a gallon


is a good ';catch all'; ratio.
