ENGINE OIL CHANGE AND FILTER
REPLACEMENT
The recommended oil and filter change interval is based
on FSS or 1 year. Please refer to the heading FSS System
in this section for a full description of the use and
interpretation of symbols in the FSS system. Only use
synthetic engine oils, approved to MB 229.3 or MB 229.5,
such as Mobil 1 SAE 0W-40. The FFS may not alert for an
oil change at the proper interval if an unapproved engine
oil is used; engine damage and reduced engine life may
result. Information is available from your authorized
dealer. The oil filter should always be changed when the
oil is changed.
