Well don't I know it! The only reason I started this thread was to find out why Mercedesshop.com sold that stuff if it was supposedly not any good for your car! I guess I got my answer'S'!!

It's unfortunate that you had to realise what most already knew.
At 130,000 miles on your engine, normally it would not require disassembling as you did.
The lower portion of the M/B engine's life could be infinent taken care of properly.
The bearings surfaces are as new, and the cylinderwalls still show the machining marks with little or no top cylinder ridge.
Typically at 150,000 miles and higher, the engine might require cylinderhead service.
What I'm trying to impress upon you is the long engine life to be expected provided it doesn't get a diet of metal objects through the induction system.
