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

NOTICE
Certain types of engines may have
crankshaft with drill-through type drive
plate mounting holes. Apply threadlocking sealant to prevent any oil
seepage through the drive plate bolts.
➢ Apply on all threads a low/medium
strength thread-locking adhesive
that seals fasteners and are tolerant
to engine oil.
