Engine Oil
The SAE numbers tell you the oil's
viscosity or weight. Select the oil for
your car according to this chart.
Ambient Temperature
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).
Maintenance
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 cost
of operating your car.
Changing the Oil and Filter
Always change the oil and filter
according to the time and distance
(miles/kilometers) recommenda-
tions in the maintenance schedule.
The oil and filter collect contami-
nants that can damage your engine if
they are not removed regularly.
Changing the oil and filter requires
special tools and access from
underneath the car. The car should
be raised on a service station-type
hydraulic lift for this service. Unless
you have the knowledge and proper
equipment, you should have this
maintenance done by a skilled
mechanic.
1. Run the engine until it reaches
normal operating temperature,
then shut it off.
