Three new spin-on oil filters, equipped with a fully synthetic filter medium, for Volkswagen passenger cars have recently been added to MANN-FILTER's comprehensive product range.

The innovative design of the three new filters is obvious even from the outside. The W712/95 filter, which is fitted horizontally to the engine, and the W712/93 and W712/94 filters, which are mounted vertically with the opening at the bottom, are all painted silver to symbolises the fully synthetic, high-performance filter medium used. The colour also distinguishes the filters from the previous black models with a cellulose-based filter medium (W712/90 – 92).

The fully synthetic filter medium ensures an improved oil supply to the engine because the differential pressure of the filter medium is lower and the grid structure allows the lubricant to drain far more effectively. This minimises wear on the engine and extend its life. The significantly lower differential pressure also causes the bypass valve to open less frequently and for a shorter time. This means that more filtered oil reaches the lubrication points. The differential pressure advantages of the synthetic medium with drainage grid are particularly important during cold starts when oil viscosity is high. Fully synthetic filter media is also much more resistant to embrittlement than conventional products over the service life.

The two vertically installed spin-on oil filters W712/93 and W712/94 have a further benefit in that they can be changed more easily and efficiently, because they are equipped with a tried-and-tested attachment containing a seal that is pressed onto the drainage channel via spring force. This ensures that the drainage channel is sealed when the filter is screwed in place. This design means that the oil flows out of the filter and the flange into the sump before the main seal is opened during filter changes.

MANN has already started serial production of these high-performance filters for the 1.0 litre, 1.2 litre and 1.4 litre petrol engines of many Volkswagen Group models. The new line of spin-on aftermarket oil filters provides a like for like OE replacement.
