    Engine Oil and Filter - Change

    ! WARNING

    Hot oil and components can cause personal injury.

    Do not allow hot oil or components to contact skin.

    NOTICE: A 500 hour engine oil change interval is available, pro- vided that the operating conditions and recommend- ed multigrade oil types are met. When these require- ments are not met, shorten the oil change interval to 250 hours, or use an S·O·S Services oil sampling and analysis program to determine an acceptable oil change interval.

    If you select an interval for oil and filter change that is too long, you may damage the engine.
