Gasoline-Oil; Engine Break-In - Yamaha SR10RDG 2015 Operator's Manual

Gasoline-Oil

Recommended Gasoline
The recommended gasoline to use in
these snowmobiles is 87 octane regular
unleaded. In many areas, oxygenates are
added to the gasoline. Oxygenated gaso-
lines 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.

SR10SD46 Models
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-venti-
lated area. Never add gasoline to the
snowmobile gas tank near any open
flames or with the engine running. DO
NOT SMOKE while filling the gas tank.
Do not sit on the snowmobile 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 conditions.
This engine does not require any pre-
mixed fuel during the break-in period.
