I'm going to have to look on my receipt... I know that he said "the oil filter is $10 to $15 more expensive than the standard one." I'll get back to you guys about it.

Here's an interesting little bit of info I've come across:
The FSS on some MB cars was standard at about 10,000 miles per oil change and on some would go up to 20,000 miles before a recommended service on even non-syn oiled cars. According to one site, even for older cars, MB now uses the solely fleece oil filters on all of their cars. The paper to fleece switch, now recommended on all MB cars (which also involves a standard oil to syn oil switch), is probably MB's way of trying to dodge any additional payouts / engine rebuilds on those older cars. It just so happens that we're stuck under the same specification...

IMHO: The FSS was a bad idea from the start. All they are doing is giving people a reason to change their oil less frequently.
