The difference between third party and genuine oil filter
Most of us have asked ourselves the question “Why should I choose genuine or OEM oil filter, whereas a third party filter is supposingly of the same quality and much cheaper?” At Autohaus Dietler we always try to offer the best value for money to our customer. The real question of course is: “Why is the use of genuine or OEM oil filters strongly recommended by us?” The answer is simple: because of the higher quality. This includes filter body material and exact measurements.
Modern engines generating much higher oil pressure than the older engine generation. This guarantees the lubrication of all moving parts. An oil filter must be hard enough to withstand that pressure but in the same time permeable enough to ensure the barrier-free oil flow.
Bellow is the comparison between a third party oil filter and a genuine Mercedes-Benz filter pulled out of 2.5l diesel engines.
