Engine Oil

Use synthetic engine oils, approved to MB 229.3 or MB 229.5, such as Mopar part number 05127394AA. Synthetic SAE 0W-40 or SAE 5W-40 engine oils approved to API SL and/or GF-3 may be substituted. The FSS may not alert for an oil change at the proper interval if an unapproved product is used; engine damage and reduced engine life may result.
