First make sure the car isn't leaking any oil from anywehere... If it
is, then synthetic will make it leak faster.
I switched both my old Buicks over to Mobil 1 (5-30 in that case) after
about 100K miles of regular oil. Just make sure it's not leaking
first, and then when you first swtich, make sure to change it with the
engine HOT, so as much of the old oil/sludge as possible is out of
there... Use a high quality filter and change as recommended by the oil
Works great for me. I will switch my 190e very shortly, when I get to
my first oil change (113K) and replace the valve cover gaset :~)
Your car is gas engine and you are running diesel engine oil... that's fine
actually... I done this myself too... However, I am a big believer in
synthetic now... Way better engine response and synthetic is far superior to
dino... I like the extended oil change too.
I suggest you go with 0W40 as MB uses on all their cars now... You should be
able to buy them at Target or Walmart... cheaper than auto places.
