Mercedes-Benz E-Class Maintenance Schedule (2017)

Your 2017 Mercedes-Benz E-Class opens the W213 generation (2017–2023). Two engines cover the 2017 model year: the 2.0L turbocharged inline-four in the E 300 (engine code M274) and the 3.0L twin-turbocharged V6 in the Mercedes-AMG E 43 (engine code M276). Both engines follow the same maintenance schedule below — the intervals don't differ by engine for the 2017 E-Class.

Mercedes-Benz runs two alternating service packages: Service A and Service B. The first Service A lands at 10,000 mi or 12 months, then Service A repeats every 20,000 mi or 24 months. The first Service B lands at 20,000 mi or 24 months, and it also repeats every 20,000 mi or 24 months — so an A or B visit shows up roughly every 10,000 miles or 12 months, alternating between the two. Whichever letter is due, the visit is built around the same underlying oil-change rhythm; the letters mostly tell you what else happens alongside it. For the broader Mercedes-Benz service framework this schedule sits inside, see the Mercedes-Benz maintenance schedule overview.

Oil and the Service A/B Pattern

Service B covers everything Service A does and adds the cabin activated-charcoal dust filter, which is replaced at every Service B for the E-Class. Engine oil and filter service happens at every Service A and every Service B, so effectively every 10,000 miles or 12 months. Mercedes-Benz USA's prepaid maintenance chart confirms synthetic oil and filter at every 10,000-mile step.

It helps to think of Service A and Service B as one continuous 10,000-mile rhythm rather than two separate schedules. At 10,000 mi you get Service A. At 20,000 mi you get Service B, which repeats the Service A work and adds the cabin filter. Then Service A comes due again, and the two keep alternating on that same 10,000-mile, 12-month cadence. Oil and filter change every time, regardless of which letter is due — there's no visit on this schedule where you skip the oil service.

This matters more than it sounds. An owner who only remembers "Service B" as the real service and treats Service A as optional ends up going 20,000 miles between oil changes instead of 10,000. Both letters carry the same oil and filter work; the letter tells you whether the cabin filter also gets swapped that visit.

Transmission and Drivetrain

Automatic transmission fluid service on the 2017 E-Class is due at 60,000 mi. No time-based limit is given alongside this figure and no severe-service variant is listed, so mileage is the only trigger for this service on either engine. That means a car that covers 60,000 miles quickly is due sooner by the calendar than one driven lightly, even though both reach the same number on the odometer eventually.

Neither the E 300 nor the E 43 gets a different transmission fluid figure in this schedule — the 60,000-mile interval applies across the 2017 E-Class lineup covered here.

Brakes, Cooling and Spark Plugs

Brake fluid is a time-based service: every 24 months, regardless of mileage. The maintenance booklet states this plainly — "Every 2 years – Replace brake fluid" — for all E-Class models. Mercedes-Benz USA's prepaid chart places the same service at every 20,000-mile step, which lines up with Service B, so in practice you'll see it done at each Service B visit.

Spark plugs go 50,000 mi or 60 months for both the E 300 (M274) and the E 43 (M276). The maintenance booklet lists this interval for gasoline engines, which covers both the M274 and M276. Mercedes-Benz USA's prepaid chart shows the same service repeating at 50,000 and 100,000 miles, which confirms the interval holds steady rather than shortening on a second pass. Severe use — short trips, excessive idling, or sustained high-speed driving — may call for earlier replacement, per the booklet. That severe note is not a separate mileage figure; it's a reason to check the plugs sooner if your driving matches that pattern, not a shortened default interval.

Because both engines share the same spark plug figure, there's no need to look up a different number for the AMG E 43 versus the standard E 300.

Engine coolant is the longest interval on this schedule: 150,000 mi or 180 months. Both the M274 and M276 share this interval. Most owners will never reach it during a normal ownership stretch, which is exactly why it's worth logging rather than trusting memory. A car bought used with an unclear service history is the one case where checking coolant condition matters more than trusting the odometer against this interval.

Filters

The engine air filter interval is 50,000 mi or 60 months for both the E 300 and E 43. The 2017 booklet lists this for the engine family that covers the M274 and M276 among others. Replace it more often if you drive in heavy dust, per the booklet's note — that guidance applies regardless of which of the two engines you have, since the booklet doesn't split the dust note by engine.

The cabin air filter — the activated-charcoal dust filter — is replaced at every Service B, which lands at 20,000 mi or 24 months and repeats on that same cadence. This is the one filter tied directly to the Service A/B cycle rather than its own standalone mileage figure, which makes it easy to track: if you know your last Service B date, you know your last cabin filter date too.

Between the two filters, the cabin filter comes due at every Service B, while the engine air filter runs to a flat 50,000-mile mark. Keeping the two straight means you won't replace the engine air filter early or let the cabin filter run past its Service B visit.

The fuel filter sits at 150,000 mi or 180 months, matching the coolant interval. Like the coolant, this is a service most owners won't hit within a typical ownership period, but it belongs on the same long-range checklist rather than being ignored entirely.

Between the two 150,000-mile items and the 50,000-mile pair of spark plugs and air filter, the E-Class schedule really has three tiers: the 10,000-mile Service A/B rhythm, the 50,000-mile mid-range items, and the 150,000-mile long-range items. Tracking which tier a given service belongs to is the easiest way to avoid missing one.

Easy to Miss

A few items are easy to skip:

• Spark plugs and the engine air filter share the same 50,000 mi/60-month interval, but neither is part of the standard Service A or Service B content. They're separate line items, so when your E-Class approaches that mileage or age, check that both are actually on the work order rather than assuming the visit covers them.
• Brake fluid is time-based at 24 months. A low-mileage E-Class that's simply aged past two years still needs it, even if Service B hasn't come around on mileage alone.
• Transmission fluid at 60,000 mi has no companion time limit in this schedule, so it comes due on mileage alone.
• Coolant and the fuel filter both sit at 150,000 mi/180 months — the longest intervals on the sheet, and the easiest to forget across years of ownership.
• The engine air filter and cabin air filter share a name but not a schedule: the cabin filter rides along with Service B every 20,000 mi/24 months, while the engine air filter runs its own 50,000 mi/60-month clock independent of the A/B cycle.
• Spark plugs and the engine air filter both land at 50,000 mi/60 months, so they're natural to handle in the same visit if you're already tracking one of them.
• Neither the E 300 nor the E 43 gets a shorter interval anywhere on this schedule. Every figure above — Service A/B, oil, transmission fluid, brake fluid, spark plugs, both filters, coolant, and the fuel filter — applies the same way across both 2017 engines.
