Unleaded And Leaded Fuels

Unleaded gasoline should meet the specifications ASTM D4814 in the United States and CGSB 3.5-92 in Canada.

If you operate your engine in a country other than the United States or Canada, unleaded fuels may be difficult to locate. Using leaded fuels in your engine is not recommended as engine components will last longer using unleaded fuel. 

Leaded fuel is not compatible with MasterCraft engines.
