C43 engine break in


Baby the engine for the first thousand miles per the manual, or just let her rip?

Change oil after 1000 (or sooner) or wait for the first factory scheduled change?

What's your opinion and is there any consensus?

Driving in C mode drove me nuts. Would dog the rpms and put car in 9th gear at 45mph. Went to S at about 400 miles till hit 1000.
No need to change oil before the one year service I was told. Thats what I intend to do. Have '18 coupe and love it. Use only S and S+ all the time. Had about 4 months and have about 2500 miles on it.

It is not necessary to change the oil after break-in? I found a pretty good sale on 0W-40 and am debating whether or not it's really necessary for a "fake" AMG.

Break it in properly, no need for excessive oil changes unless that’s your thing.

I never break-in an engine... I've had a Ferrari 430 and a bmw m5 before now I own a audi RS4 and a maserati (also a Shelby cobra but i'm 3th owner so no need to drive in that 5.7L engine).

Never had engine problems before and I drive very sportive. But I drive very calm when engine is cold! From the moment the oil is warm I floor it even in its first 1000miles.

I've talked to my mb salesman and he told me the same, when you start driving an AMG just open the AMG menu and check the numbers till they go white instead of blue and then you can do what U want to. If you floor the car when the numbers are blue and you've got an engine problem then I won't be fixed under waranty.

It's always amazing, to me, that people pay attention to "stuff read on the internet," people with little or no automotive engineering expertise (e.g., most sales reps) and personal anecdotes instead of the car's manufacturer ... in this case, Mercedes and AMG -- organizations that have world-class automotive engineering expertise, decades worth of experience producing and supporting vehicles, including in numerous racing/competition modes, and who spend billions of dollars in engineering, development and testing. If you've ever seen what happens inside engines at various points when they're relatively new, you'd know that the break-in advice in your Mercedes' manual is worth following.

Its worser to floor the car when the engine is cold than floor the car in his break-in period. I didn't read stuff about it on the internet I just told my experience, and my ferrari/maserati sales men is an ex rally driver.

Best way to get service adviser to not so something is to tell them you read it on a forum.
