Gasoline-Oil

Recommended Gasoline
The recommended gasoline to use in
these snowmobiles is RON 95 octane
regular unleaded. In many areas, oxygen-
ates are added to the gasoline. Oxygen-
ated gasolines containing up to 10%
ethanol are acceptable gasolines.
When using ethanol blended gasoline, it is
not necessary to add a gasoline antifreeze
since ethanol will prevent the accumula-
tion of moisture in the fuel system.
Recommended Engine Oil
The recommended oil to use is Semi-
Synthetic Yamalube 0W-30 oil.
CAUTION
Any oil used in place of the recom-
mended oil could cause serious
engine damage
After 800 km (500 miles) of operating,
the engine oil must changed and the oil
filter replaced. The engine oil should be
changed every 4000 km (2500 miles)
before prolonged storage and the oil filter
should be changed every 20,000 km
(12,500 miles).
Filling Gas Tank
Since gasoline expands as its temperature
increases, the gas tank must be filled to
its rated capacity only. Expansion room
must be maintained in the tank particu-
larly if the tank is filled with cold gaso-
line and then moved to a warm area.

Also, if the snowmobile is to remain on a
trailer after filling the gas tank, the bed of
the trailer must be maintained level to
prevent gasoline from draining out
through the gas tank vent hose.
WARNING
Always fill the gas tank in a well-ven-
tilated area. Never add gasoline to
the snowmobile gas tank near any
open flames or with the engine run-
ning. DO NOT SMOKE while filling
the gas tank. Do not sit on the snow-
mobile without first installing the gas
tank cap.
The SR10SD46 features a 15.9 L (4.2 US
gallon) auxiliary gas tank. A separate gas
tank cap is located beneath the cowling
just behind the operator seat. The auxil-
iary tank is plumbed directly into the
main gas tank.

Engine Break-In

The engine (when new or rebuilt)
requires a short break-in period before
the engine is subjected to heavy load con-
ditions.
