Break-in Period, Gasoline

Break-in Period

Help assure your car's future
reliability and performance by paying extra attention to how you drive
during the first 600 miles (1,000 km).
During this period: Avoid full-throttle starts and rapid

acceleration.
Avoid hard braking. New brakes
need to be broken-in by moderate
use for the first 200 miles (300

km).

You should follow these same re- commendations with an overhauledor exchanged engine, or when the
brakes are relined.
Gasoline

Your Honda is designed to operate on unleaded gasoline.
We recommend gasolines containing detergent additives that help prevent
fuel system and engine deposits.
Using gasoline containing lead will
damage your car's emissions
controls. This contributes to air
pollution.
In Canada, some gasolines contain
an octane-enhancing additive called
MMT. If you use such gasolines,
your emission control system performance may deteriorate and
the Malfunction Indicator Lamp on
your instrument panel may turn on. If this happens, contact your
authorized Honda dealer for service.
(U.S. DX, HX, EX models, and Canadian

DX and Si models)

Use an unleaded gasoline with a
pump octane number of 86 or higher. Use of a lower octane gasoline can
cause a persistent, heavy metallic
rapping noise in the engine that can
lead to mechanical damage.

(U.S. Si model and Canadian SiR model)

Use a premium unleaded gasoline
with a pump octane number of 91 or higher.
If you are unable to find premium
unleaded gasoline, you may substi-
tute an unleaded regular gasoline.
The engine will compensate for the lower octane, but you may notice aslight decrease in power as a result.

Engine Oil

The oil container may also display the API Certification seal. Make sureit says "For Gasoline Engines."
API CERTIFICATION MARK The SAE numbers tell you the oil's
viscosity or weight. Select the oil for
your car according to this chart.

An oil with a viscosity of 5W-30 is

preferred for improved fuel economy

and year-round protection in your

Honda. You may use a 10W-30 oil if

the temperature in your area never

goes below 20°F( — 7°C).
Synthetic Oil
You may use a synthetic motor oil if it meets the same requirements
given for conventional motor oil;energy conserving, a service
classification of SJ, and the proper
weight as shown on the chart. When using synthetic oil, you must follow
the oil and filter change intervals
given in the maintenance schedule.
Additives Your Honda does not need any oil additives. Purchasing additives for
the engine or transmission will not
increase your car's performance or
longevity. It only increases the costof operating your car.
