I am replacing the piston rings (standard size) on my 1977 300D and would like to know which brand is better: Deves, Goetze, Mahle, or another brand? An independent M-B technician (with factory training and worked at a M-B dealership before opening his own shop) told me that the rings on the early 300D's were not the best and could have been better.

Thanks,
Tom
