Z4MC running in procedure (SteveD)
- Thread starter gidge2010
- Start date
I've always driven my M cars as they should be driven right from the start, as soon as I allow enough time for the engine to warm up. I've never had an engine failed prematurely on me. This below 5000RPM for XXX miles is a waste of time, IMO

No it doesn't, you trolling twat. Why don't you try to contribute instead of posting like the child you are?
To OP - I will dig out the relevant SteveD commentary and post as soon as I can locate it
Why don't you tell him what you really think Giles
I used the SteveD method and my car is just great!! I do not plan to keep it more then 3 years.... So - can't speak for how long the engine will last....

From what I recall as the post no longer remains, the key to Steve's running in procedure is in the first 200 miles from new.
A series of taking the car up to maybe 7000 rpm on several progressive runs, in a straight line so not to put strain on the diff. Once the top suggested rpm is reached allow the car to rev down to 2-3000 rpm and repeat this procedure several times over several occasions during the 1st 200 miles. Always do this with the engine nicely warmed up.
Theory is this will assist in ensuring that the piston rings seal nicely in the chamber, additional speed through the increased rpm will help smooth the chambers nicely, much like sand papering something more quickly to get a smoother finish, resulting in a good tight engine.
First two hundred miles is the key, not much point thereafter as the piston rings will have sealed as best they can.

A serial M series owner and the reason all the Z4MCs have got CSLs, Aero skirts and strut braces.

As much as I hate to admit it, you're very likely right about that. As soon as I saw SteveD's pictures I knew that my car would be sporting those wheels also! And then the aero skirts....
Haven't done the strut brace yet, but that's because I'm going for something a little different... :shifty:
