2016 MB E350, Mobil 1 0W40, 18,092 miles

[The Critic]

Oil was in use for 11 months. Mostly highway miles. OEM interval is 1/10K.

Polaris ran this sample twice due to my concerns about the additive levels. However, the CA, P and Z levels remain unusually high for M1 0W40; not sure what's going on.

I personally installed this oil and took the sample. The owner did not top off the oil during this interval. The car was at the dealer for an unrelated electrical repair and they did not perform any mechanical work.

Edit - looks like the M1 0W40 add pack has varied depending on the batch?

This VOA from 2020 shows 3437ppm:

Ca and Zinc are a tad high, otherwise looks great. Oil still had life left. 20k was doable here.

M1 0w40 just keeps on rockin' along.

So going off that are you going to try another 15k interval?

I would prefer for him to stay with 10K. It is a higher mileage car that benefits from periodic inspections and the tires should also be rotated.

This 18k interval looks perfect here! But 9k would put them exactly at 2 times per year change. These are great results. This MB & this oil is a perfect match!

Looks like the oil held up fine.

My wife had a 2006 E350 4MATIC I ran exclusively on M1 0W-40 up to around 130,000 miles before selling it. Changed oil myself ever 10K. No issues apart from some electricals and the dreaded known camshaft misalignment failure that was resolved under warranty after a class action lawsuit. Was a comfortable and classy ride. Replaced with a C300 4MATIC SUV. Less comfort and rough riding on imperfect roads when NOT loaded. Blaming the Pirelli run-flats. Looking forward to their replacement but anticipate at least another 20K on them before done.

Well, a DI motor by Mercedes and the oil is fine after 18k miles!

@The Critic, you say your client does mostly highway miles? Do you reset his trip odometer at an oil change to see his actual average speed by the oil change time? My wife has the same car (2016 too) and although her commute feels like “mostly freeway”, in actuality her average speed by the oil change is a mere 28 mph, time after time

It's about the same. Lots of traffic on the highway here.

18,000 miles at 28 mph translates to 640 hours on the oil. this is just awesome . Mercedes’s 1year/10k mi interval errs on a safer side

That's quite an impressive result. No make oil over 18k on a modern MB gas engine is something as well.
