As we already know that MAHLE oil filters are often reliable. They prevent contaminants from entering the vehicle’s lubrication system. This in turn enhance the performance and efficiency of the engine.
“Thanks to stable pleat geometry, cold start stability is assured. Load peaks up to 20 bar are compensated due to the high pressure resistance of the housing. A pressure relief valve guarantees the oil supply under all conditions – for viscous oil encountered during cold starts or at low temperatures, for extremely contaminated filter elements, or when the replacement intervals have been exceeded. A non-return flow valve prevents the draining of the filter when the engine is switched off and ensures adequate oil supply when the engine is started. High-grade sealing materials and custom-fit connecting pieces assure reliable separation of contaminated and filtered oil.”

Let’s take a different type of MAHLE oil filters
MAHLE Oil Filters Cartridges
With filter cartridges from the OX program we offer particularly economical solutions for repair shops: instead of replacing the complete filter, only the dirty filter element has to be renewed. This is an ecologically sensible solution that saves material and disposal costs. In the Eco version, the cartridges are metal-free and can therefore be completely incinerated. Oil filter cartridges are available for all oil filters with removable housings.

MAHLE Hydraulic Spin-On Filters And Filter Cartridges
Hydraulic spin-on filters with increased wall thickness and more stable end plates are specially matched to the high pressures in hydraulic systems of up to 40 bar. Often the multifaceted collar is eliminated to allow greater pulsation dampening. More durable materials such as special non-wovens and synthetic media are used in hydraulic spin-on filters and filter cartridges, since hydraulic oil contains different components.
Special spin-on filters and filter cartridges that are suitable for use with hydraulic oil are available.

Spin On Filters
If one considers the tendencies in the original equipment sector it becomes clear: in addition to a trend towards increased type variety for replacement filters—due to new engine designs and restricted space in the engine compartment—a distinct increase in service intervals can be noticed.
Filter service life spans of 30,000 km and more are now common for many new vehicles and some manufacturers are even quoting 50,000 km—driving patterns and the quality of engine oil taken into account. However, a longer service life does not necessarily mean less sales revenue. This is because the longer the replacement interval, the more important the quality of the oil filter.

Cellulose Free Filter Medium
Increased service life makes also higher demands on the filter media in oil filters, particularly as the new engine generations with direct injection increase the problem of oil aging. With the use of new fully synthetic high performance oils, replacement intervals of up to 50,000 km are reached—with a trend to even longer intervals.
However, due to the new general conditions, conventional filter raw materials are becoming less suitable, especially as the excessive nitration of the oils leads to embrittlement of the filter medial. The response from MAHLE: a fully synthetic two-layer fleece made of polyester, consisting of a support and a filtration layer. This makes it possible to achieve highest filtration performance with best stability—and at the same time block forming in the pleats can be avoided. Compared with cellulose fibres, the aging stability of the new oil filter medium is 7 times higher—and it offers the same or even lower pressure drop at significantly increased dirt pick-up capacity. The new cellulose free filter media are, for instance, available for Mercedes-Benz vehicles in the Aftermarket.

Spin On Oil Filter Mix Up
A spin-on oil filter consists of housing and filter element, which are inseparably connected and must therefore be changed as a unit. However, the problem is that many filters look identical but have completely different insides depending on the engine.
For example, they may be with or without anti-drain valve or have different connection threads. They also can differ in the oil pressure of the bypass valve, filter media, the fineness of the filter or the permissible operational overpressure.
