What’s the Difference Between Mercedes Service A and Service B

Factory maintenance schedules are developed by auto manufacturers to ensure your vehicle is getting the care it needs throughout your ownership. Most manufacturers recommend a tiered maintenance schedule, covering essential routine services like oil changes more frequently, and larger inspections or services like brake fluid flushes less frequently.

Mercedes-Benz uses an easy naming convention for their tiered services: Service A and Service B. If you are a new Mercedes-Benz owner, this article will help you understand the details of each service, and how often they need to be done to get the most out of your car.

Note: This article covers the services for Mercedes models 2009 model year and newer. Certain diesel, AMG, and V12 engine vehicles will follow slightly different service schedules.

What is a Mercedes-Benz Service A?

Service A occurs at the first 10,000-mile interval from new or one year, whichever comes first. After the initial Service A, the interval changes to every two years or 20,000 miles. Service A performs the following:

  • Synthetic Oil Change and Filter Replacement
  • Check fluid levels and correct them as needed
  • Check tire inflation
  • Inspect brakes
  • Reset the maintenance reminder

Not all models are the same. When your vehicle is getting its Service A performed, the technician will consider the unique features of your specific model and perform any required services that go beyond the basics.

What is Mercedes-Benz Service B?

The first Service B occurs at 20,000 miles or one year after the last service. It then follows a two-year/20,000-mile interval, alternating with Service A. Service B includes many of the same maintenance items as Service A, with the addition of a few more.

  • Synthetic oil change and filter replacement
  • Check fluid levels and correct them as needed
  • Check tire inflation
  • Inspect brakes and change brake fluid
  • Reset the maintenance reminder
  • Replace cabin and engine air filters

As with Service A, this is a general list of services that all vehicles will need. Your technicians will consider the specific needs of your exact vehicle.

Is 10,000 Miles too Long for an Oil Change Interval?

While the factory recommendation is every 10,000 miles, we find that to be insufficient. To get the most life out of your Mercedes-Benz and protect the engine from damage, you should consider getting an oil service every 7500, or even every 5000 miles depending on the vehicle’s age and how you drive it. More frequent oil changes will cost you more, but it will almost certainly be less than repairing a damaged engine that did not receive proper lubrication.
