Engine oils
Engine oils are specifically tested for
their suitability in our engines and
durability for our service intervals.
Therefore, only use engine oils and oil
filters required for vehicles with the
Maintenance System. For a listing of
approved engine oils and oil filters
contact an authorized smart center.
!
Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System, or
changing of oil and oil filter at change
intervals longer than those called for by
the Maintenance System will result in
engine or emission control system
damage not covered by the smart Limited
Warranty.
Please follow Maintenance System
recommendations for scheduled oil
changes. Failure to do so will result in
engine or emission control system
damage not covered by the smart Limited
Warranty.
Viscosity grades for engine oils

according to the lowest air temperature
