About 100:1 Pre-Mix 2-Stroke Outboard Oil
A premix two-stroke outboard oil; use only the mixing ratio permitted for the product and engine. Compare the current AMSOIL application information with your equipment’s service documentation before planning the job. Keep the product code ATOBC-EA handy when reviewing package options or asking Jeff a question.
Before you choose
Check whether your engine uses premix, oil injection, or another lubrication arrangement. Follow the specified oil standard and mixing directions for this exact product and engine.
Can I use any two-stroke oil?
No. Air-cooled, marine, racing, and injected engines can have different requirements. Match the application and manufacturer instructions; a shared two-stroke label does not establish compatibility.
