Fuel Information
Fuel recommendation
Unleaded premium gasoline, pump octane number 91 or higher
4-cylinder models
Use of a lower octane gasoline can cause occasional 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.
6-cylinder models
Your vehicle is designed to operate on premium unleaded gasoline with a pump
octane of 91 or higher.
If this octane grade is unavailable, regular unleaded gasoline with a pump octane
of 87 or higher may be used temporally.
The use of regular unleaded gasoline can cause metallic knocking noises in the
engine and will result in decreased engine performance. The long-term use of
regular-grade gasoline can lead to engine damage.
Top tier detergent gasoline
Because the level of detergency and additives 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.
Fuel Information
NOTICE
We recommend quality gasoline 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 recommend, 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, and cause the malfunction
indicator lamp on your instrument panel to come
on. If this happens, contact your dealer for service.
Some gasoline today is blended with oxygenates
such as ethanol or MTBE. Your vehicle is designed
to operate on oxygenated gasoline containing up
to 10% ethanol by volume. Do not use gasoline
containing methanol. If you notice any undesirable
operating symptoms, try another service station or
switch to another brand of gasoline.
