My car is due for its 2nd oil change sevice. During the 1st service, the authorized dealship used an oil filter of a brand I hadn't encuntered before. I'm wondering if the M139 oil filter is the same as the one used in the Mercedes-Benz A45s. I bought a Mann oil filter for A45s, it looks quite similar ( or I should say identical) to this one, but price is only 20% of the German one.
