Kestas,

I think part of the reason that you never heard of this with other brands is because the MB dealers began using a very nice oil suction system in the dealerships. This was done for shop efficiency, not because it does a better job.

Taking this to the next step, there are those that think that if the dealer does it this way, it must do a better job.

Thus, the topsider entered the picture.

I, as you, never, ever heard of using such a device at home before finding mercedesshop and sharing much dialog with all these great MB owners.

Have a great day,
