Frequently Asked Questions

Honda engines are developed, tested and certified with petroleum based motor oils as a lubricant. Synthetic oils may be used; however, any motor oil used in our engines must meet all oil requirements as stated in the owner’s manual. In addition, recommended oil change intervals must be followed.

Please see your owner's manual for detailed instructions for your specific model.

Never. Honda's internal timing belt is 100% maintenance free.

As the name implies, overhead cam (OHC) engines have their camshafts positioned in the cylinder head above the combustion chamber. Valves are located in the roof of the combustion chamber (instead of at the side) to offer the same combustion-related advantages as OHV engines.

The OHC layout builds on these advantages by reducing the number of valvetrain components and allowing them to be lighter and stronger, thereby making the engine more compact and lightweight overall.

OHV stands for “overhead valve.” Intake and exhaust valves are located above the combustion chamber for superior efficiency, performance and durability.

Honda engines are designed and certified to run on regular unleaded gasoline containing no more than 10% ethanol (E10).

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 (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 engines are not certified or designed 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 more information, see our Fuel Recommendations page.
