OIL FILTERS QUALITY THAT PAYS OFF
Mercedes-Benz Genuine Oil Filters really are the best option for your customers according to an independent report. The IFTS – International Filter Testing Service – conducted a variety of tests on both petrol and diesel oil filters from four different sources including Mercedes-Benz. The IFTS looked at key requirements including manufacturing quality, pressure resistance, dirt-holding capacity and separation efficiency. The results speak for themselves.
PRESSURE RESISTANCE
The pressure resistance of the oil filter is measured in a collapse/burst pressure test. The oil pressure in the engine gives rise to a difference in pressure between the entrance and the exit of the filter. If the oil filter is unable to withstand this pressure and collapses, unfiltered oil will find its way into the engine. This is usually not discovered until the next vehicle service, with increased wear and tear, reduced engine performance and, in the worst case, expensive engine damage with corresponding time off the road as the outcome.

Mercedes-Benz GenuinePart: The Mercedes-Benz genuine oil filter had no problem coping with the high difference in pressure. Hengst: Likewise, the Hengst oil filter coped well with the increased difference in pressure.
FRAM: The FRAM oil filter was not able to withstand the increased difference in pressure. Following the test, the filter pleats showed considerable deformation and, in some cases, had stuck together. The filter showed leakage in the area around the adhesive at the end cap. Unfiltered oil can reach the engine.
Pirated version: In this test, the end cap became detached on one of the two test speci- mens, leading to a total failure of the filter. In this case, unfiltered oil reaches the engine.

Major European manufacturer: Likewise, this oil filter coped well with the increased difference in pressure. However, the lines of glue on the filter, responsible for keeping the pleats in place, have a tendency to break. The filter loses its shape somewhat.
