I can't believe this old oil thread is still going. I just checked my post which said I have 305k on my wagon. I now have 345k on the same engine. You guys with all the extra discretionary income can keep feeding the corporate ads by buying into the tauted special oils, but I will continue to buy any name brand 20/50 oil on sale. Although my 83 300TDT with 345k on the clock doesn't burn any oil, has plenty of power, and fires right up on cold morns, there is a chance that by not using expensive special oil I may not reach 500k. I guess I will just have to take my chances. The other drawback to using cheap oil is that I have nothing to brag or talk about at cocktail parties. I guess that is why I never get invited. These are just the ramblings of a 30 year MB mechanic with millions of miles on MBs if you include client cars with trouble free miles. By the way MB says you should not go to 10 weight on turbos because of the high thermal stresses.
