Fills uneven surfaces in engine
The oil must maintain a lubricating oil film between load bearing surfaces. In rod
bearings this film ranges between 5 and 15 microns in thickness. This film prevents metal
to metal contact reducing wear.
Lubricate
Most of the heat produced by a diesel engine is waste. One job of the oil is to absorb some
of that waste heat and transfer it to the air by way of radiation to the atmosphere or transfer
to the cooling system through the oil cooler.
Cool
Even with today’s machining processes, sealing surfaces are not perfect. The oil fills in
the gaps in areas such as between piston rings and liners to act as a seal, improving
engine performance.
Seal
The oil is also used to transport additives to all parts of the engine. Detergents keep the
engine clean, while dispersants keep small particles from becoming large, wear causing
particles.
Clean
The hydraulic properties of oil are used to operate items like hydraulic valves
and exhaust brakes.

Evolution of Products
OBJECTIVE
To give understanding as to the role of lubricating
crankcase oil filtration from its grass roots concept
through to a new patented filter concept extended
oil service
The presentation is formatted to show how
Fleetguard’s dedication to achieving finer filtration
has not been disregarded at the expense of
achieving greater service intervals and filter life.

Real World Contamination
75% to 90% contaminant
ORGANIC (sludge)
Fleetguard's extensive field tests have shown, < 20% of total
matter trapped by a lube filter is inorganic (dirt), the
remainder is organic sludge material.
Combustion By-Products
Consist Of…
By-products of combustion form at
least 80% of the oil contaminate
Effects Of Sludge
Oil fails because the
dispersant package is no
longer capable of keeping
the soot in suspension.
• As soot builds up it agglomerates and falls out of suspension.
• Then forms sludge and interferes with the desired functioning
of the oil.
• It also becomes somewhat abrasive in the system.
• Plugs filters.
• Removing sludge forming materials from the system allows oil
to perform effectively for longer periods.
Stacked Disc Bypass Media
Stacked Disc removes
3 to 5 times as much
material as the full
flow element.
Compressed fibres,
NO RESIN BINDERS
Stacked Disc bypass filter media not only removes fine
damage causing particulate, it provides the attraction
medium (cellulose) for sludge holding.
