The oil and Genuine Mitsubishi filter are the key ingredients to engine performance and longevity. Regular oil and filter changes prevent excessive engine wear; keep the engine cool; and ensure long term reliability. When oil changes are extended beyond recommended intervals, engine sludge can form. Sludge obstructs oil passages and restricts oil flow, leading to premature engine damage.
The repair of damages caused because the parts or services used were not those prescribed by the Warranty and Maintenance Manual, is not covered under warranty.
Replacement interval not to exceed 7,500 miles with non-turbo models. Turbo engines require an accelerated oil and filter change frequency. Check your maintenance schedule for specifics.
