Your Mercedes-Benz vehicle requires specific fluids to avoid engine failure and to maintain its optimum performance.
Approved Engine Oils
Engine oil must satisfy many different industry standards and manufacturer requirements. The most common oil ratings are:
Mercedes-Benz has very specific engine lubrication requirements and only oils that have a MB approval number and the approved viscosity ranges are to be used when servicing your engine. The MB approval number is marked on the oil container similar to Figure 1. Verify the correct MB approval number on the individual oil container or accordingly for oil available in bulk quantities.
Current diesel engines absolutely require low SPAsh oils. Use the newest oils with optimal viscosity protection and with the latest MB approval number 229.51.
For U.S. Vehicle Models prior to MY2007, please refer to the Factory Approved Services Products brochure on STARTekInfo.com.
Engine Oil Viscosity Range Chart
The oils and viscosity grades with MB approval numbers are for the US market. Use the newest oils with optimal viscosity protection and with the latest MB approval numbers, such as MB approval 229.5 or 229.51 (except SLR 155 engine). Select oil viscosity grades according to the lowest and highest air temperature expected before your next oil change.
