OPERATION
BREAK-IN PERIOD
ENGINE BREAK-IN
Polaris recommends the use of POLARIS Blue 2-Cycle Semi-Synthetic Oil for
your snowmobile, including extreme arctic conditions with a sustained
temperature at or below -40° F (-40° C).
NOTICE
Use of any lubricants other than those recommended by POLARIS may cause
serious engine damage. We recommend the use of POLARIS lubricants, or an
equivalent product, for your vehicle.
Always follow these recommended break-in procedures for new or rebuilt
engines. The first tank of fuel is considered the break-in period for the engine.
Premix the first tank of fuel and fill the oil bottle with the recommended oil. Oil
added to the fuel and oil injection systems will provide the necessary engine
lubrication.
INITIAL FUEL PREMIX
The first tank of fuel should contain a 40:1 ratio of fuel to oil premix.
NEVER mix oil brands. Serious chemical reactions can cause injection system
blockage, resulting in serious engine damage. Oils may be incompatible and the
result could be sludge formation, filter blockage, and reduced cold weather flow
rates. All POLARIS oils are compatible with each other.
Always premix fuel in 5 gal (19 L) increments in a separate fuel container. Never
add oil directly to the fuel tank.
POLARIS BLUE 2-CYCLE
FUEL SEMI-SYNTHETIC OIL RATIO
Each 5 gal (19 L) 16 oz (473 mL) 40:1
FIRST THREE HOURS OF ENGINE USE
Excessive heat build-up during the first three hours of operation will damage
close-fitted engine parts. Do not operate at full throttle or high speeds for
extended periods during the first three hours of use. Vary the throttle openings
and vehicle speeds to reduce friction on all close-fitting machined parts, allowing
them to break in slowly without damage.
Drive with extra caution during the break-in period. Perform regular checks on
fluid levels, lines, and all other important areas of the snowmobile.
OIL INJECTION SYSTEM
Always check and fill the oil bottle during pre-ride inspection and refueling.
