2018 E400 Wagon
break in period
Just got a 2018 e400 wagon, a leftover from last year, in designo diamond white. I want to know, do I need to follow the 1000 miles break in? I have a amg package, and now going over 500 miles on it. I have kept it under 3k rpm, and looking to see what is necessary. I am coming from owning 5 bmws, which I never abided by any break in policy. any input would be appreciated!

Just my $.02:
When I used to have English cars there was a theory that every now and then you had to rev them during the break in period. Further driving at a constant speed, for example 60 mph was not recommended - but rather varying your speed.
The exception were brakes: gradual braking not hard stops so as not to leave burn spots on the rotors.
With today's modern engines and lubricants much of what we used to do are relics and no longer applicable.
Personally, I do not drive my E450 hard, it is after all a luxury car!
Is there anything specific in the owner's manual about break in? If so, to be on the safe side, follow whatever it says. If not, be conservative in your driving for the first 1,000 miles and Good Luck!

Yes, follow the 1,000 break in recommendation. I have finally hit 1,000 miles on my car and today was the first time I drove in Sport mode.

You just spent a lot of money. Do you think the MB engineers know what they are recommending over what owners itching to see what their new car will do off the line. I remember the same debate when I was a teenager in the 60's, you have to get into it with that new 348 cu in engine or it will be a dog off the line.

Well I figure if I could keep it under control on the autobahn I can maybe do the same on the NASCAR track we call I-17 in Phoenix.
