2 Check the oil level in the engine

The oil level in the engine should be

checked each time the fuel tank is filled.

The check should be carried out with the

engine switched off but warm and, in order

to obtain comparable values, about 1

minute after the engine has been stopped.

Wipe the dipstick before measuring. The

oil level should be between the two marks

on the dipstick. It must never be per-

mitted to go down below the lower mark

but, on the other hand, it should not be

above the upper mark since oil consump-

tion will then be abnormally high. If

necessary, top up by filling through the oil

filler hole on the rocker-arm casing with

new oil of the same type already in the

engine.

3 Change oil in engine

With a new or newly reconditioned engine,

the oil should be changed after the first

2500 km (1500 miles). Subsequent oil

changing is according to the intervals

given below. The intervals will depend to a

great extent on the type of oil used. For

engine lubrication, oil quality "For Service

MS", is to be used. As far as viscosity is

concerned, multigrade oil is recommen-

ded. These oils are better suited for de-

manding driving conditions, for example

continuous driving in city traffic with in-

cessant stopping and starting and with

l engthy idling periods.

For engine oil with viscosity SAE 10 W-30

(multigrade),10 W-40,10 W-50 or 20 W-50

the oil should be changed every 10 000 km

(6000 miles), or at least once a year.

If engine oil with viscosity SAE 10 W sing-

l egrade), 20/20 W or 30 is used, the oil

should be changed every 5000 km (3000

miles), or at least twice a year.

At very low temperature (below -20° C,

-4° F) multigrade oil SAE 5 W-20 is re-

commended. However, this oil should not

be used when the temperature is conti-

nuously above 0° C (32° F).

The old oil is drained off by removing

the drain plug on the sump. Drainage

should take place after driving when the

oil is still warm.
