4.4.2. Lubrication oil exchange

Engine oil and the oil filter are important factors affecting engine life. They affect ease of starting,

fuel economy, combustion chamber deposits and engine wear.

The first engine oil change should be after 50 hours of operation and next exchange will be

performed every 250 hours. At the end of the break-in period (50 hours), change the engine oil

and replace the oil filter cartridge to new one.

(1) Oil drainage

•

While the oil is still hot, discharge the

sump oil or marine gear sump oil by

rotating oil drain pump manually.

•

Refill new engine oil to the oil filler

neck on the head cover in accordance

with the oil capacity of the engine. Be

careful about the mixing of dust or

contaminator during the supplement

of the engine oil.

Then confirm that the oil level gauge

indicates the vicinity of its maximum

level.

•

For a few minutes, operate the engine

at idling in order to circulate oil

through lubrication system.

•

Thereafter shut down the engine. After waiting for about 10 minutes, measure the quantity

of oil and refill the additional oil if necessary.

•

Recommendation for lubrication oil

Initial factory filling is high quality break-in oil (API Service CH-4 grade). During the break-in

period (50 hours), check the oil level frequently. Somewhat higher oil consumption is normal

until piston rings are seated. The oil level should be maintained in the safe range between

the Min. and Max. mark on the dipstick. To obtain the best engine performance and engine

life, Engine oil is specified by API Service, letter designations and SAE viscosity numbers. If

the specified engine oil is not available, use a reputable brand of engine oil labeled for API

Service CH-4 and SAE viscosity 15W40 or 10W40.

Refer to oil identification symbol on the container.
