20. USE FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE
REMARK
•
We recommend Komatsu genuine lubricants (Spectrum XXX) oil which has been specifically formulated and
approved for use in engine and hydraulic work equipment applications. (See reference table on page 3-14)
•
Only use high quality oils wich meet internationally recognised specifications.
•
When starting the engine in an atmospheric temperature of lower than 0
SAE10W, SAE10W-30, SAE15W-40 and synthetic 5W-30, even though an atmospheric temperature goes up
o
to 10
C more or less in the day time.
•
Use API classification CE or CF-4 as engine oil and if API classification CD, reduce the engine oil change
interval to half.
•
There is no problem if single grade oil is mixed with multigrade oil (SAE1OW-30, 15W-40), but be sure to add
single grade oil that matches the temperature in the table.
•
When fuel sulphur content is less than 0.5%, change oil in the oil pan every periodic maintenance hours
described in this manual.
Change oil according to the following table if fuel sulphur content is above 0.5%.
Fuel sulphur content I
0.5 to 1.0%
1.0% to 1.5%
Specified capacity: Total amount of oil including oil for components and oil in piping.
Refill capacity: Amount of oil needed to refill system during normal inspection and maintenance.

•
If an engine is operated in ambient temporatures consistently below -23°C (-10°F) and there are no provisions
to keep the engine warm when it is not in operation use a synthetic API performance classification CE or CF-
4 engine oil with adequate low temperature properties such as SAE SW-20 or 5W-30.
The oil supplier must be responsible for meeting the performatic service specifications.
NOTICE
The use of a synthetic base oil does not justify extended oil change intervals. Extended oil chance
intervals can derease engine life doe to factors such as corrosion deposits and wear.
Change interval of oil in
engine oil pan
1/2 of regular interval
1/4 of regular interval
o
C, be sure to use engine oil of
