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

vehicle production date) or FSS PLUS (Canada
vehicles, depending on vehicle production date),
or changing of oil and oil filter at change intervals
longer than those called for by the Maintenance
