Function in detail
The oil filter plays a vital role in maintaining the health of the engine. The materials and geometry of the folded paper within each filter is of critical importance. The more refined the folding technology, the more efficiently the filter surface can be deployed so that the oil filter
works more effectively. The result: the engine oil can remain serviceable longer and the oil change intervals can be extended.
Benefits
Optimal cleaning
Dirt particles in the oil are normally smaller than 5 ΅m that is less than 0.005 of a millimeter! Genuine BMW Oil Filters hold these smallest of particles and even smaller wear particles or residues in the filter and pass on only pure, clean oil.
Long operating lifetime and less engine wear
Genuine BMW Oil Filters are manufactured from cellulose reinforced with synthetic fibers. This helps to prevent the filter medium becoming brittle or forming cracks, so preventing dirt particles from reaching vital lubrication areas. Engine and lubrication parts are significantly better protected by the high filter properties. This in turn leads to reduced engine wear and maintains performance.
High dirt particle capacity through large filter surface
An especially important criterion for the quality of a filter is its folding geometry: the goal is to maintain the greatest possible filter surface with minimum space. That is because the larger the surface of the Genuine BMW Oil Filter, the more dirt it can capture. Unfolded, the surface of a Genuine BMW Oil Filter would cover between 1,900 and 3,800 cm2. BMW Oil Filters also maintain the correct rate of oil flow
for each specific engine.
Perfect sealing quality
As well as perfect filtering, BMW Oil Filters also ensure that the return flow inhibitor functions optimally and that no unclean oil from the filter intake or the bypass valve gets back into the oil circuit.
Outstanding protection
Oil filters are extremely important components. When oil filters are contaminated by use beyond their replacement mileage, they not only increase fuel consumption but also are often the cause of massive damage in the engine. With Genuine BMW Oil Filters, you are
guaranteed when changing the filter that the replacement filter exactly matches the BMW specification for this component.
Easy installation
Genuine BMW Oil Filters have an extremely compact design that is exactly matched to each vehicle model. The accuracy of fit and easy access in the engine compartment make installation simple and uncomplicated.
Environmentally friendly construction
In the past, screw-on oil filters were common: when the oil filter was changed, both the filter medium and the filter housing were replaced. Today, BMW widely uses environmentally friendly and easy-to-maintain oil filters that through the additional impregnation with phenolic
resin are highly corrosion-resistant and thus durable. The filter housing itself is made of aluminum. For service, however, the filter medium is usually replaced.
Quality assurance
Genuine BMW Oil Filters protect engine and lubrication parts from contamination. Their quality directly influences the
lifecycle of these components and is therefore of vital importance. BMW tests the following five key performance factors on a regular basis:
Filter unit
The dust separation efficiency (criteria for the filter performance) is tested to precise tolerances with comprehensive tests of the filters ΅m range.
Mass per unit area and caliper
Samples of the filter paper are stored at +100 °C for at least 30 minutes and subsequently conditioned to a standard. Quality control takes place only after this endurance test to check whether the mass per unit area still matches the exact specifications. The specified paper
strength is also checked against the reference paper.
Tensile strength
The hardened and brittle filter paper of the reference sample may only give way under excessive load. That allows precise conclusions to
be made about the stability of the paper in a moist, oil-saturated state.
Bursting strength
In order to prevent oil from escaping in the event of an accident, the entire oil filter is tested to destruction. The higher the sustained
pressure before it bursts, the better the component quality.
Bubble test
The pressure required to let air bubbles pass through a paper sample saturated in liquid is measured.
