Lubrication Points

For the details of lubrication points and types of lubricants to be applied, refer to the Illustrated Index and various work

procedures (such as Assembly/Reassembly, Replacement, Overhaul, Installation, etc.) contained in each section.

*1: If Honda MTF is not available, you may use an API service SG or SH-rated motor oil with a viscosity of SAE

10 W-30 or 10 W-40 temporarily. Motor oil can cause increased transmission wear and higher shifting effort, so you

should have the transmission drained and refilled with Honda MTF as soon as possible. The transmission should be

drained and refilled with new fluid according to the time and distance recommendations in the maintenance schedule.ProCarManuals.com

Engine Oil

Replacement

CAUTION: Remove the drain plug carefully while the en-

gine is hot, the hot oil may cause scalding.

1. Warm up the engine.

2. Drain the engine oil.

API CERTIFICATION MARK

The numbers in the middle of the API Service label tell

you the oil's SAE viscosity or weight. Select the oil for

your car according to this chart:

Ambient Temperature

An oil with a viscosity of 10W —30 is preferred for im-

proved fuel economy and year-round protection in the

car.

You may use a 5W —30 oil if the climate in your area is

limited to the temperature range shown on the chart.

4. Fill the engine with oil up to the specified level, run

the engine for more than 3 minutes, then check for

oil leakage and oil level.ProCarManuals.com

Engine Oil
Inspection
1. Check engine oil with the engine off and the car parked on level ground.
2. Make certain that the oil level indicated on the dipstick is between the upper and lower marks.
3. If the level has dropped close to the lower mark, add oil until it reaches the upper mark.
CAUTION: Insert the dipstick carefully to avoid
bending it. Replacement
