I am wondering too if synthetic will reduce the gear noise
in my W124 (87 260E). I was told by the mechanic that the
noise from the back when I drive is from the differential
which he says has been quite worn out. However he says you
can still drive it for years without any problems. However
the noise bother me sometimes. I wonder if I switch over
to something synthetic it would reduce it. If it does the
I think its worth teh money.
