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 re-

System (U.S. vehicles) or FSS (Canada 
vehicles). For a listing of approved engine 
oils and oil filters, refer to the Factory Ap-
proved Service Products Pamphlet, or 
contact an authorized Mercedes-Benz 
Center.
Using engine oils and oil filters of specifica-
tion other than those expressly required 
for the Maintenance System 
(U.S. vehicles) or FSS (Canada vehicles), or 
changing of oil and oil filter at change inter-
vals longer than those called for by the 
Maintenance System (U.S. vehicles) or

damage not covered by the 
Mercedes-Benz Limited Warranty. Please follow Maintenance System 
(U.S. vehicles) or FSS (Canada vehicles) 
recommendations for scheduled oil 
changes. Failure to do so will result in 
engine damage not covered by the
