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 1,000 km (600
miles).
During this period:
Avoid full-throttle starts and
rapid acceleration.
If you need to add oil, use the
engine oil recommended in this
owner's manual.
Avoid hard braking. New brakes
need to be broken-in by moderate
use for the first 300 km (200
miles).
You should follow these same re-
commendations with an overhauled
or exchanged engine, or when the
brakes are relined.
Before Driving
Gasoline
Your Honda operates most effec-
tively on 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.
We recommend gasolines con-
taining detergent additives that
help prevent fuel system and
engine deposits.
Using gasoline containing lead will
damage your car's emission
controls. This contributes to air
pollution and can void certain parts
of your warranty.
Oxygenated Fuels
Some conventional gasolines are
being blended with alcohol or an
ether compound. These gasolines
are collectively referred to as
oxygenated fuels. To meet clean air
standards, some areas of the
United States and Canada use
oxygenated fuels to help reduce
emissions.
If you use an oxygenated fuel, be
sure it is unleaded and meets the
minimum octane rating require-
ment.
Before using an oxygenated fuel,
try to confirm the fuel's contents.
Some states/provinces require this
information to be posted on the
pump.
