How do you properly break in an engine?

[tonjohn]

I will soon be getting a new MCS and i was wondering how to properly break in the engine. I want this car to last me for a very long time so i want to break it in as best as possible.

ALl help is greatly appreciated!

This will likely start a lively discussion. There is another thread going on this. I would go/am going with the owner's manual instructions, for the first 1200 miles, under 4500 rpm, under 95 mph. Very your speeds, after the first 1200 miles you can ramp up your rpm's.

Think about it, this car comes with a good warrantee and maintenance agreement, why risk that by not following the manufacturer's break-in (run-in) procedure?


I am up around 700 miles now and the engine seems to be running in just fine.

I asked the same question a couple of months ago. See this thread

I agree, just never flog it in any particular gear for long periods , I kept to 5000 rpm, for 1000 miles, and then started to open it up...I'm due a first oil change next week.Like any 16v engine they get better as they loosen up.

Engine is fine, it's just little things like a noisy fan on the a/c and a rattle in the dash , that let the package down so far.
