What is the ratio of oil and gas that I need to mix for my Nissan 2-Stroke outboard?
With the exception of our outboards which have oil injection systems, Nissan 2-stroke outboards require a 50:1 (2.5 ounces of oil for each gallon of gas) oil/gas mixture after the initial break-in period. Nissan outboards which have oil injection will automatically mix the correct amount of oil and gas depending on the engine requirements; you don’t have to pre-mix your oil & gas with these systems. We’ve put together a handy chart to help you calculate the amount of oil/gas to mix.
