Hi Sandra, I hope you didn't really put oil in the Honda outboard fuel tank. The lubricating oil is in the closed crankcase, and most likely that doesn't need filling or attention for a whole season. The ONLY thing you put in the fuel tank of a 4 cycle HONDA outboard is clean gasoline - not a drop of oil! A Honda engine is a four cycle engine. The lubricating oil for the engine is in the closed crankcase. The engine only requires gasoline to operate. No gasoline / oil mixture. ~~~~~~~~~~~~~~~ A two cycle outboard engine is different. It requires a mixture of gasoline and oil - the usual ratio is about 50:1 - and this fuel/oil mixture is what goes in the fuel tank. The oil is mixed with the gasoline which then provides the necessary lubrication for the two cycle engine. Happy sailing Connie
