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.
The AXYS engine management system utilizes both a fuel injector break-in period and oil pump enrichment program. The duration of these break-in programs are independent of each other and are timed-out based on engine run-time. Regardless of these automatic engine break-in / enrichment features, the following engine break-in procedures must be performed when the engine is new or overhauled.
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.
