There is lots of opinions as to how you should run a new car in. I got a Leon Cupra R 225 yesterday, and was wondering which method I should use. So far I have found.....

Cane it from day 1.
Let the brakes and clutch bed in for 20 miles and cane it.
Run it gingerly for 200 or so miles and then open it up.
Run it gingerly for 800 - 1000 miles and then open it up.

Are there any opinions on any of this ??

I know I have to take it easy until the oil is up to temperature but not sure how else to do it.

I would say the fourth one down.
Mate of mine had a Saxo VTS picked it up from the dealer caned it from day one, Sounded terrible after 5000 miles also had trouble with flat spots through the revs.
Good choice of car but why not a scooby.

 

no higher than 4000rpm for the first 1000 miles on a new scoob,then let her have it.

 

Came across this site the other day...

Run under the 4000 rpm mark for 1000 miles then gradually increase the revs over the next 500 miles, also take longer to brake so you run those in too

Thanks guys, that what i thought.

Its sooooo difficult not to floor it though !!! Will have to put a brick under the loud pedal methinks !!

Barking, just read the webpage.

Surely, if run-in affects ring sealing so much then the difference should be measurable with a compression leakage test?
Where is the data to support the theory I say?

 

I followed that link and....
I see they dont mention running in the rest of the car like the diffs, cv joints, bearings, gearbox, brakes etc, but no doubt the "professional mechanics" didnt look at the rest of the car thinking that it would be ok
Do that method if you want to naff your car up quickly, do the manufacturers way if you want it to last more than 10k.
