    I have a 1954 Elgin 7.5. I have been using "Amsoil Saber 100:1 outboard oil" at 40:1. I'm scared to go much less than 40:1 but have been doing so for a couple of years. It is the everyday motor for my sailboat so although it doesn't get long haul use it does get used often enough. This has virtually eliminated the smoke and makes starting easier.

    Avoid it if you can, you motor was not engineered for today's blended gas. Try to locate straight un-blended fuel
