to run-in or break-in...

[Guest zerod]

i know the manual has a run-in caution. (some says this is to protect MB lawfully)

According to online web http://www.mototuneusa.com/break_in_secrets.htm Break-in makes sense.

Also looking at the video on C-Class making in factory.. they actually run you engine to max... so why that manual run-in caution?

Any opinions from pros?

[Guest snsd555]

i think there are 2 school of thoughts, hard to say which one is really correct.

i do the normal run-in though..

[Guest zerod]

yeah i think so too its hard to say.. i personally feel normal run-in till i saw the factory in Bremen runs the engine hard

Bench run in as seen in the video is different from actual on the road run in. What the manual says actually helps running in not only the engine but the entire drive train. Both need to be run in together.

I will follow what the manual says.

I followed the manual. To me - it's a short 1500km to take it easy so that I can worry less about the many times more km to follow so no point risking anything. It's now completed and behind me and I can enjoy my driving henceforth.

Personally fully agreed w bro Jtang.

Always followed e manual recommended mileage to run-in my ride. Drive as per normal daily footer.(NO J.Lopez on e flr) :silly:

Look at those huge machinez handlg heavy items: panaramic roof, top to bottom chassis, doors, deskboard, engine etc... My word: Solid!

You can see these robots at work close up when you visit the factory in Stuttgart. It is indeed amazing to see it twist and turn to fit a complete dashboard through the door opening and assemble it in one action; insert and bolt.

What I find clever is the logistic part of having different configuration on a same assembly line; different spec and color.

Mr. Yap - More than 20 years ago when I visited Madza Plant in Yokohama Japan, not only they have diff specs and colors but diff models of car running 929, 626, 323 all running on the same line :ohmy:

My FL C180K passed the 2000km after close to 2 months, this week.

I was driving on the traffic filled PIE on Wed morning, when it cross the 2000km mark. Once I passed the traffic obstruction, I accelerated gently, and I could feel the difference. I felt that the engine has become smoother and the changing of gears were much smoother as well, too bad only up to 5th gear. I wound down the windows at a quieter road, and heard that the engine was quieter as before when reving it.

When my wife (new driver) drove the next day, she asked why it seem more powerful.

So can conclude that there is still the need to run or break in.

My experience to share with you.
