Snowmobile Break-In - Polaris MATRIX INDY VR1 Series Owner's Manual

SNOWMOBILE BREAK-IN

ENGINE BREAK-IN
Engines equipped with an electronic oil pump do not require initial fuel premix.
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.
Never mix brands of oil. Serious chemical reactions can cause injection system
blockage, resulting in serious engine damage. Oils may also 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.
Drive with extra caution during the break-in period. Perform regular checks on
fluid levels, lines, and all other important areas of the snowmobile.
