Someone at work found out that I'm into MBs. Maybe he got close enough to smell the Diesel fumes on me He asked me why his mom's 99 E300 with ~40K miles vibrates like the stereotypical Diesel. Makes clacking noises it didn't used to make. Glow plugs and motor mounts are new. Are there typical causes? Water? Delivery valves?

Will it harm a 606 to have a Diesel purge treatment or pour a gallon of Mazola in the fuel tank?

Thanks,

Start with the lubro moly treatment. My 99 E300TD Responded very well to it.
There are two lines right rear side of the engine bay (feed and return). Disconect the two clamps and shove on two 12" hose extentoins with some copper tubing to join the existing hoses. Then an extra piece of hose to connect the two steel lines together. Use an old coffee can stick the two hose ends in the can. Crack open the LM pour it in the can . Start up the car and let it run
Follow the directions on the LM can.

Is the check engine light on? If not, I'd go with Anthony's reccomendations.. or just run a few tanks with some Redline in it.. did wonders for my car too in terms of quietness/nailing/injector knock.

Thanks Anthony and td.

For Red Line, do you recommend 85 Plus or Diesel Fuel Catalyst?

How about trying a couple bottles of gas dryer and fresh fuel filters.
