Break in period

I am taking delivery of my new E320 Friday and have a 1000 mile trip planned immediately thereafter. My dealer says my car will not need a break in period. I did not give my last luxury car a break in period and there were no problems. However, I've talked to a few other MB owners, and have done a little reading, and the consensus seems to be there should be a 500 mile or so break in period. I do not have the owners manual at this time. I'd appreciate any advice you can give me. Thanks.

RE: Break in period

MB does include a "break-in" procedure for new cars in the owners manual and I would highly recommend doing a "break-in" or you will regret it later. Here is what I've done with each and every one of my 30 cars so far (including 9 MB):

For the first 500 miles:

1. Keep engine RPM below 4000
2. Keep speed below 75 mph
3. Do NOT drive at any one speed for more than 10-20 minutes - vary speed up and down
4. No "jack-rabbit" starts and no hard braking - easy does it.

For the next 500 miles:

1. increase RPm's with an occasional shot to almost redline
2. drive as fast as you want, but not "full-out" for extended period
3. drive at any one speed for 30 to 45 minutes
4. brake hard occasionally to prevent glazing

After 1000 miles: drive normally and just enjoy the thing.. I would also NOT change oil as recommended by the FSS - I change mine every 5000 miles and use full synthtic Mobil 1 for European cars. Good luck.

RE: Break in period

I would agree with most of this except: Don't drive at any steady state speed for ANY length of time, definitely not for 10-20 minutes (no cruise control). Don't be afraid to get into the throttle, but never give it WOT. If you can, dump the break in oil after 500-600 miles. After 600 miles (and the first oil change), drive it like a rental if you want. New mass produced motors aren't built "tight" enough to need more than that. This has served me well for almost 30 years.

RE: Break in period

I believe that's what break-in periods are for. You should allow all the gaskets and oils to properly seal and lubricate the engine to maximize it.

Diving into the 1000mile trip immediately after delivery is just like running into a marathon without any conditioning or any warm-ups.

RE: Break in period

This was written for motorcycles but it is appropriate reading here. Something to consider anyway.....
