My Toro commercial lawnmower has a Suzuki 2-stroke engine. I've used Royal Purple, Amsoil and Echo two-stroke oil. I bought this oil because I have owned Lawn-Boys in the past and have only used Lawn-Boy 2-Stroke Oil. Never had a problem. Now that I've bought this oil, I'm not sure I should trust my expensive Suzuki engine with this oil? I gave it 5 stars because I know my lawn mowers love this oil. Glad it's still available.
