History of Motor Oil Filters. Motor Oil
Filters Have Come a Long Way Since the
First Design was Introduced in the1920's
Motor oil filters have come a long way since the first design was introduced
in the 1920s.
One of the most important functions of motor oil is to capture and suspend
contaminants and wear particles, preventing premature wear on an engines
internal parts. Acting alone, motor oil would quickly become saturated with
these contaminants and wear materials and would require very frequent changing,
perhaps as often as every 500 miles, in order to effectively guard against wear.
It is an engines oil filter which allows motor oil to last for an extended
period of time.
The earliest automobiles did not have any sort of oil filtration, and it was
common to change oil every 500 to 2,000 miles. Later, as pressure lubrication
became standard on automobiles, some kind of oil filtration was necessary in
order to protect the oil pump from damage and wear. Early designs were quite
primitive, often consisting of nothing more than steel wool, wire meshes or
screens placed in the oil pump intake. Many designs were cleanable and reusable.
The earliest incarnation of the modern oil filter came about in 1923, when
Ernest Sweetland introduced his invention known as the Purolator, a combination
of the words Pure Oil Later. Incorporated into the lubricating system after the
oil pump and before the oil flows into the engine bearings, the original
Purolator featured an upright series of seven twill weave cloth-covered,
perforated plates encased in a heavy-duty cast container. It also had a sight
feed glass on one side, enabling the owner to see the oil flow and change the
filter when flow slowed to a trickle.
James A. Abeles saw enough potential in the Purolator to convert a New York City
garage into a company called Motor Improvements Inc., developed primarily to
manufacture Purolator filters. The Maxwell Chalmers Company also saw promise in
this new product, installing a Purolator on a Maxwell automobile which was
test-driven on a round-trip from Detroit to the West Coast in 1924. The longer
oil drain intervals, cleaner oil and reduced engine wear offered by the
Purolator ensured endorsement by the automotive industry, and they soon became
standard on many popular automobiles of the day, including Studebaker, Pierce
Arrow, Hupmobile, Peerless, Cadillac, Oakland, Gardner, Moon, Jordan, Buick and
Oil filter technology continued to progress over the years. In the late 1930s,
cotton waste material was introduced as filtration media, providing the first
filter replacement capability. Various woven fabrics were also used in some
filter designs. By 1946, as disposable filter models became the norm and
interest in saving production costs increased, materials such as pleated paper
and cellulose became the filtration media materials of choice, materials that
are still widely used in todays oil filters.
Prior to 1943, most oil filters were of the by-pass variety, only filtering
about 10 percent of the oil at a time. The first full-flow oil filter, capable
of filtering 100 percent of the motor oil, was introduced in 1943 and became
standard on mass production vehicles by 1946.
The modern disposable "spin-on" oil filter design was introduced in 1955,
replacing cartridge-type filters which had to be placed in a special housing or
canister. The technology progressed throughout the 1960s and spin-on oil filters
soon became standard on virtually all American, European and Japanese automobile
Todays spin-on oil filters resemble metal cans that encase the filtration media,
which capture and hold the various organic and inorganic contaminants and wear
metals within the motor oil. Organic contaminants include bacteria and other
organisms that make up sludge, while inorganic contaminants include dust and
An engines oil pump pumps motor oil from the oil sump to the oil filter. Dirty
oil passes through the oil filter media, where it is cleaned before flowing to
the central tube and back into the engine through the mounting stud. Oil is then
distributed by oil passages throughout the engine.
By-Pass Oil Filters Secondary by-pass oil filters act separately from an engines
full-flow filter and only filter a small portion of the oil in a system at a
time, subjecting it to additional and more thorough cleaning than the full-flow
filter is able to provide.
Various styles of by-pass systems exist on the market today. Some feature
centrifuge or thermal action, spinning or boiling out contaminants, while others
feature extremely efficient media that remove smaller contaminants. Originally
marketed as a way to effectively extend equipment life, the use of by-pass
filters are also effective in keeping oil clean and capable of extended drain
The AMSOIL Advantage - AMSOIL is the Only Supplier of a 25,000 mile or 12 Month
Oil Filter in the World.
As previously mentioned, many of todays conventional oil filters make use of
pleated paper or cellulose as their filtration media. Although these filters
usually display good flow characteristics when new, they tend to become
obstructed fairly quickly. In addition, these conventional filters exhibit
limited capacity, longevity and ability to catch fine particles.
AMSOIL Absolute Efficiency Oil Filters (EaO) are designed for maximum
efficiency, capacity and longevity, while meeting the high flow demands of
modern engine designs. In fact, with its advanced filtration media composed of a
special Cellulose, Nano Fiber Technology, Synthetic and Glass Blend, extensive
testing shows that AMSOIL Ea Oil Filters achieve a near-perfect absolute
efficiency rating. The exclusive new technology used in AMSOIL EaO Filters
provides filtering efficiency to 98.7 percent at 15 microns. EaO Filters are the
most efficient filters that are available for auto/light trucks.
AMSOIL EaO Filters are also approximately 50 percent efficient at 7 micron
nominal particles. In addition, AMSOIL Eao Filters are designed for extended
drain intervals of 25,000 miles or 12 months (whichever comes first), making
them ideal for use in conjunction with premium AMSOIL Synthetic Motor Oils.
AMSOIL By-Pass Filtration Advanced engine designs place tough demands on an
engines full-flow filter, most of which are capable of efficiently filtering out
only coarser wear particles, generally greater than 20 to 25 microns. However,
approximately 60 percent of engine wear is caused by particles in the 5 to 20
micron range. These tiny particles closely match the precision clearances
between critical engine components, entering the spaces between bearings, rings
and other components and damaging metal surfaces, altering tolerances, fatiguing
components and generating additional debris. For the ultimate in filtration
efficiency and wear protection, AMSOIL offers the Spin-On By-Pass Oil Filter.
The AMSOIL EaO By-Pass Oil Filter provides the best possible filtration on the
market, protecting against wear, oil degradation, rust and corrosion. Situated
outside the main line of oil circulation, the AMSOIL By-Pass Filter works in
conjunction with the full-flow filter, thoroughly filtering 10 percent of the
oil at a time and removing wear-causing contaminants down to less than one
micron in size. The AMSOIL By-Pass Filter effectively filters all the oil in a
six quart system in about five minutes at an average speed of 45 mph.
Water enters motor oil as a combustion by-product or as a condensate. When it
contaminates motor oil, it can cause serious engine damage by causing metal
surface rust and corrosion, which increases friction and wear and deteriorates
the close-fitting tolerances between engine components. It can also react with
other contaminants to form corrosive acids, which also damage metal components.
The AMSOIL By-Pass Filter effectively removes up to a pint of damaging water,
significantly increasing the time oil can be safely left in the engine.
The effectiveness of the AMSOIL By-Pass Filter lies in its construction. Its
high-capacity filtration medium is a special blend of virgin wood, Nano
Technology Synthetic Fibers, and cotton fibers, formed into discs, stacked and
compressed. The center tube is all-steel, perforated for oil flow and wrapped
with a fine mesh cotton screen. Each filter includes a mounting unit with a
spin-on filtering cartridge, connected by hoses to engine ports. The entire
by-pass system fits into most cramped engine compartments, allowing quick and
easy access. Particles sized down to less than one micron are trapped and
removed, while the filters thirsty cellulose fibers remove water.
By-Pass Filter Accessories: The AMSOIL Dual Remote Oil Filtration System allows
an AMSOIL Super Duty Oil Filter and an AMSOIL Spin-On By-Pass Filter to be
attached onto a remote mount, providing easy access for both filters. Remote
placement of the Dual Remote system allows larger oil filters to be used and
increases oil sump capacity.
The AMSOIL Dual-Gard Filtration System links two AMSOIL By-Pass Filter elements
together for engines with sump capacities greater than 20 quarts.
