Fuel Information
■Fuel recommendation
Use of a lower octane gasoline can cause a persistent, heavy metallic knocking noise
that can lead to engine damage.
Use of a lower octane gasoline can cause oc casional metallic knocking noise in the
engine and will result in decreased engine performance.
Use of a gasoline with a pump octane less than 87 can lead to engine damage.
■Top tier detergent gasoline
Because the level of detergency and additive s in gasoline vary in the market, Honda
endorses the use of “TOP TIER Detergent Gasoline” where available to help
maintain the performance and reliability of your vehicle. TOP TIER Detergent
Gasoline meets a new gasoline standard jointly established by leading automotive
manufacturers to meet the needs of today's advanced engines.
Qualifying gasoline retailers will, in most cases, identify their gasoline as having met
“TOP TIER Detergent Gasoline” standards at the retail location. This fuel is
guaranteed to contain the proper level of de tergent additives and be free of metallic
additives. The proper level of detergent ad ditives, and absence of harmful metallic
additives in gasoline, help avoid buildup of deposits in your engine and emission
control system.
Unleaded gasoline, pump octane number 87 or higher
Unleaded premium gasoline, pump octane number 91 or higher

NOTICE
We recommend quality ga soline containing
detergent additives that help prevent fuel system and
engine deposits. In addition, in order to maintain
good performance, fuel economy, and emissions
control, we strongly reco mmend the use of gasoline
that does NOT contain harmful manganese-based
fuel additives such as MMT, if such gasoline is
available.
Use of gasoline with these additives may adversely
affect performance, a nd cause the malfunction
indicator lamp on your inst rument panel to come on.
If this happens, contact a dealer for service.
Some gasoline today is blended with oxygenates such
as ethanol. Your vehicle is designed to operate on
oxygenated gasoline containing up to 15% ethanol
by volume. Do not use gaso line containing methanol.
If you notice any undesira ble operating symptoms, try
another service station or sw itch to another brand of
gasoline.
