Engine Oil Maintenance Information

Poor oil maintenance reduces the engine oil
lubrication and cooling capacities. As a result,
internal engine parts can be damaged resulting
in abnormal wear to internal engine parts,
excessive carbon deposits, sludge, and other
various conditions. An inspection for these
conditions and others may be required prior to
engine approval.

Piston Ring Deposits

NOTICE
Engine oil is used to lubricate, cool, and
operate various engine parts. Engine oil
changes and engine oil level checks are
required on a regular basis for all engines.

Oil Sludge

Engine oil level checks and top-ups are
recommended if they are needed prior to
the end of an oil change interval.

Excessive Wear
