What type of gasoline is recommended for my sterndrive engine? Should I use gasoline that contains alcohol?
In the USA and Canada, any major brand of unleaded automotive fuel with a posted pump octane rating of 87 minimum is safe for gasoline engines. Premium gasoline (92 octane) is also acceptable. DO NOT use leaded gasoline. Outside the USA and Canada, use gasoline that has a posted pump octane rating of 90 RON minimum. Premium gasoline (98 RON) is also acceptable. If unleaded gasoline is not available, use a major brand of leaded gasoline. Reformulated (oxygenated) gasolines are required in certain areas of the USA. The two types of “oxygenates” used in these fuels are alcohol (Ethanol) or ether (MTBE or ETBE). These reformulated gasolines are acceptable for use in your engine. If the gasoline in your area contains either Methanol (methyl alcohol) or Ethanol, you should be aware of certain adverse affects that can occur. See your operation and maintenance manual for details. In older engines that were designed to run on leaded fuel, use Quicksilver valve lubricant to avoid the possibility
