Engine oils

Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters
required for vehicles with Maintenance
System (U.S. vehicles, Canada vehicles,
depending on vehicle production date) or
FSS PLUS (Canada vehicles, depending on
vehicle production date). For a listing of
approved engine oils and oil filters, refer to
the Factory Approved Service Products
pamphlet (USA only), or contact an autho-
rized Mercedes-Benz Center.
