Running in period....

[whitenemesis]

What is it with this running in all it takes is one day to clock up 1000 miles.
South of France then on the way back give it some pastie over the alps

Whilst I guess this was slightly tongue-in-cheek, it's worth mentioning "motorway miles don't count". So unless one were to drive to the south of France only using rural roads you'll not be doing the engine/drivetrain much good.

And it would take longer than 1 day

Interesting. I've had discussions with both Brabus and Vaeth on breaking in a freshly built alusil engine and both companies recommended using standard (Brabus) and thick grade (Vaeth) synthetic oil whilst driving the car on the motorway for at least 800 miles with as less turning the ignition off as possible, gradually increasing the load on the engine but not exceeding 70mph.

I've always been told it's the variation in revs and load that bed the components. Running at a constant speed on the motorway was considered bad practise.

Then I was also advised to do an oil change after 500 miles.

Guess times (and oil and engines) have changed...

Get it up to temperature (the oil that is) and give it some stick!

Il gaurentee that on the pdi road test at the dealer nobody paid any attention to any running procedure.

and then there is this approach:

Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power

Has a certain logic to it?

That's been around for years ... does "some bloke on the Internet" really know more about running-in car engines than the people who make them?? I wouldn't personally gamble on it with a vehicle I'd bought with my own money and planned to hang on to - I'd do what the handbook said!

The pdi and fuel fill only clocked 11 miles and the sales guy who dealt with it all was pretty **** about the AMGS he was more excited about mine than me I recon he looked after it but who knows. Im not too concerned i used to be an m3 nut, I owned a gorgeous 04 cab which was 6 years old when I got it, I read lots of horror stories about them but it was a fantastic car. I also bought a 3 year old Impreza turbo with 90k on which I did another 20000 trouble free miles in. I'll look after the AMG and I'm sure it will look after me

I'm currently running in a new OB C63 saloon, only 250 miles to "hammer time", gradually of course.

I've had a couple of ex demo cars in my time, a R172 SLK 55AMG and a Honda S2000 and I'm sure that no one ragged them during test drives :roll eyes: but both cars had no apparent engine issues further down the line despite what a lot of members of various forums said.

However where possible I always try and stick to what the manufacturer recommends as they should really know best, so it's 4500rpm max for the next 250miles......

Yes, I agree, nothing new there, but that doesn't make it wrong (in principle). This is very similar to other descriptions of race engine build and running in process to achieve highest power.

Having said that, I follow the manual instructions, don't rack up too much motorway mileage, and avoid high-load/high revs or high load/low revs early in the process and increase loading over time.

Cheers,

I could very easily be wrong but If it was as straight forward as he suggests I would have presumed it would be easier doing this at the factory instead of having to wait 1,000 miles knowing that most of these engines will have been on a bench for testing at the factory anyway.
