Have Honda Questions? Ask a Honda Repair Expert.
Hello I will help you with your question,
You can use regular fuel in your engine which is 87 or 85 octane depending on the area of the country you live in.
You can find that information on the Honda page linked HERE

Let me know what further questions you have about this
If you are at sea level to 2000 ft of elevation you can use 87 or higher but the regular grade of 87 will be fine. At higher elevations the octane will be less as there is less cylinder pressure so you can use the 85 octane sold there.
In any case your engine will perform fine on regular fuel there is no need for mid grade or premium but if that is all that is available it will be fine with those as well. Your wallet will take a hit though.
