Mercedes Engine Running-in

I have a 1982 500SL and just putting the finishing stages to a new rebuilt engine .

Appreciate your views on upto date methods of running-in a new engine .

If I follow the Mercedes 1982 owners manual, it states that you treat the engine very gently for the first 1500KM and to vary the engine load and RPM during that period, but not to rev high or stress the engine .

Is this information the same today for new Mercedes engines .

I have read views that the engine should be driven hard from the start to " Bed the rings in "

Appreciate your comments and help on this topic.

The first 250-300 miles are the most important ones...NO full throttle..no lugging... BUT constant engine speed changes..

I agree with MBDoc but would only add that I think that lugging a fresh engine is the worst thing that you can do. That's not to say that you should spin it up to the redline. I guess what I'm saying is to take care to follow MBDocs instructions but avoid lugging at ALL costs. That is pretty easy to do with an automatic. Lugging usually only occurs with a manual.

Good luck,

And change that first charge of oil soon after, such as 500-1000 miles.

I'm just curious (and I feel a bit dumb) but what do you mean by "lugging"?

Skiier, lugging, is being in too high a gear, with too much throttle. You're on a ten speed bicycle, in 8th gear, going up a steep hill. Seond to lugging, is idling. Prolonged idling of a new engine will also cause it's demise.
