Frequently Asked Questions
Honda engines are designed and certified to run on regular unleaded gasoline.
Gasoline is allowed, by regulation, to contain a variety of additives. The same regulation limits how much of some additives, such as alcohol, can be included in the fuel and still allow it to be sold as gasoline. If you look in a Honda product owner’s manual, you will see that a maximum of 10% ethanol is allowed in gasoline (other oxygenates are also listed). Honda engines are designed for good performance and efficient operation using gasoline containing from 0 to 10% ethanol.
E85, a mixture of 85% ethanol and 15% gasoline, has been in the news recently. E85 is an alternative fuel; it is not gasoline. Honda Marine engines are not currently designed or certified to run on E85 or any other alternative fuel.
Always refer to the owner’s manual for your Honda to get a list of recommended fuel and the current approved additives.
For other gasoline related questions, please see the Fuel Recommendations page.
Honda engines are developed, tested, and certified with petroleum based motor oils as a lubricant. We recommend Honda Marine 10W-30 FC-W engine oil or 5W-30M engine oil (see your owner’s manual for recommended oil) available through your local Honda Marine dealer. Honda FC-W Marine engine oil is specially formulated for use in marine engines and has several advantages over automotive oil. See your owner’s manual for oil change intervals.
