Engine Oil

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

An oil with a viscosity of 5W-30 is
preferred for improved fuel economyand 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 vehicle's performance or longevity. It only increases the
cost of operating your vehicle.

Transmission Fluid

5-speed Manual Transmission Check the fluid level with the
transmission at normal operating temperature and the vehicle sittingon level ground. Remove the
transmission filler bolt and carefully
feel inside the bolt hole with your
finger. The fluid level should be up
to the edge of the bolt hole. If it is
not, add Genuine Honda Manual
Transmission Fluid (MTF) until it starts to run out of the hole. Reinstall
the filler bolt and tighten it securely. If Honda MTF is not available, you
may use an API service SG, SH or SJ
grade motor oil with a viscosity of SAE 10W-30 or 10W-40 as a
temporary replacement. An SG
grade is preferred, but an SH or SJ
grade may be used if SG is not available. However, motor oil does
not contain the proper additives and
continued use can cause stiffershifting. Replace as soon as
convenient.
The transmission should be drained and refilled with new fluid according
to the time and distance recommen- dations in the maintenance schedule.
