# Mercedes-Benz E-Class Oil Change: Three Generations, One Indicator

Every E-Class from the 2010 W212 on schedules its oil through ASSYST Plus, and Mercedes-Benz dealers place the first Service A at about one year or 10,000 miles, then about every 20,000 miles or two years, with oil and filter at both Service A and Service B. The 2.0-liter four in later E 300 and E 350 models is commonly listed at about 6 liters with an MB 229.71 oil, while the E 450's M256 six holds far more, about 9.9 liters on Engine Oil Journal's chart, with approvals your manual names.

★★★★★ 4.7 stars from 952 Google reviews

The E-Class is the long-distance Mercedes, and around Carson City it is often the car that does the state-government commute in the morning and the drive to Reno for dinner. It has run through three generations here: the W212 (2010 to 2016), the W213 (2017 to 2023) and the W214 that arrived for 2024. Engines changed with each one, from V6 and V8 gasoline engines and a BlueTEC diesel to today's turbo four and inline six with 48-volt assist. The oil changes with them.

## E-Class engines and what they list

The four-cylinder capacity is from AutoPadre's E 350 lookup and the E 450 figure from Engine Oil Journal's Mercedes capacity chart; AutoPadre gives a lower figure for some E 450 years, so we go by the manual and the dipstick or electronic level reading on your car. BLAU Parts lists MB 229.71 for the 2.0-liter turbo four in the E 350.

| Generation | Common US engines | Oil commonly listed | Oil with filter |
|---|---|---|---|
| W212, 2010-2016 | 3.5 V6 (E 350), 4.7 V8 (E 550), BlueTEC diesel | MB 229.5 gasoline; MB 229.51 or 229.52 diesel | Read the manual for your engine |
| W213, 2017-2023 | 2.0 four (E 300, later E 350), 3.0 six (E 450) | MB 229.71 on the four; six per manual | About 6.0 L on the M264 four |
| W214, 2024-on | 2.0 four (E 350), 3.0 six (E 450) | Per manual; E 450 shown with MB 229.52 or 229.61 | About 9.9 L on the E 450 |

## How ASSYST Plus words it

Mercedes's ASSYST Plus system does the counting. Mercedes-Benz of Arcadia describes it as calculating service needs from driving habits, time, mileage and environmental conditions, and an indicator lights when a visit is due. The display names it as Service A or Service B. Mercedes-Benz of Buckhead lists motor oil and filter replacement in both.

If you ignore the reminder, the display counts overdue days or miles. We would rather see an E-Class before that happens, and we reset the oil service in ASSYST Plus as part of every visit.

## Carson City cold, Carson City heat

The Carson City weather station averages 146 nights a year at or below freezing and about 40 days at 90 F or hotter (NOAA 1991-2020 normals). An E-Class parked outside a state office on a January morning starts in serious cold, then spends August afternoons in a hot parking lot. That swing is the honest reason to keep the approved low-friction oil the manual lists, and to have the coolant level and the battery looked at before winter.

Carson City households have a mean commute of 20.5 minutes (ACS 2020-2024). Short commutes are fine for an E-Class as long as it gets a longer run now and then and its oil is changed on the ASSYST Plus date.

## The older diesel and the newer mild hybrids

A W212 E 250 BlueTEC or E 350 BlueTEC has a diesel particulate filter and calls for a low-ash diesel-rated MB approval, typically MB 229.51 or 229.52. We pour diesel oil only with the sheet number your manual lists. The latest E 350 and E 450 use a 48-volt starter-generator; the oil service is the same, but the engine stops and starts more often in traffic, and ASSYST Plus counts that.

## What else we look at on an E-Class

- Transmission: the seven-speed and nine-speed automatics use Mercedes-specified fluid. We check for leaks and point you to the booklet's interval; our [transmission fluid service](https://xpressoilandlube.com/services/transmission-fluid-service/) page explains our approach.
- 4MATIC transfer case and front axle checked for seepage.
- Engine air filter and the dust or combination cabin filter pulled and shown.
- Coolant level, brake fluid level, tires, lights, wipers and a battery test at participating locations.

## Questions people ask

Still have a question? Call your service center or drive in; there is no appointment to make.

### What oil does a 2019 E 300 take?

Its 2.0-liter turbo four is commonly listed with an MB 229.71 oil. We read your cap and manual and pour the approved oil.

### Why does an E 450 take so much more oil than an E 350?

The inline six has a much larger sump. Engine Oil Journal's chart lists about 9.9 liters for the W214 E 450 4MATIC.

### Can you do the oil on a BlueTEC diesel E-Class?

Yes, with a diesel-rated MB approval such as 229.51 or 229.52 where your manual lists it.

### Does Carson City require a smog check on my E-Class?

No. Vehicles registered in Carson City are not in a Nevada DMV emissions testing area.
