Hello all,

So if you get a new car i hear a lot that you don't need to run them in as everything is built better now a days.

Is this the same for sport cars? Since they run boost would this do damage?

Cheers.

Jump in and give it death mate, don't think it's mattered in the last 10 years at least.
My mk1 focus Rs was off the limiter in every gear from the factory, no issues

I was told you don't need to these days

But

It doesn't hurt. I ran my fiesta in properly just because it ain't gonna hurt

Depends on the car manufacturer.

An example is the new M cars from BMW, they use the same oil as the "normal" cars now, but still have to have the original "running-in" oil and diff oil changed @ 1200 miles and should not go over 4k until then.

Saw an M3 that was sold via my place that the driver took it straight to the Nurburgring. Came back to us on a trailer for warranty as the engine was knocking badly and the diff whining. Testing showed he had the TC turned off completely almost every time the ignition was turned on.

BMW threw the claim out as he had not followed the instructions.

When you buy a new car there will be specific to that model instructions regarding if it needs to be " run-in ". To avoid any warranty problems that could occur stick to whatever the manual says. It is unlikely that you will need to with most modern cars but its no big problem if you have to.
What new car are you thinking of buying?

On Tuesday i ordered the new RS3 but won't get it just yet as they need to build it but didn't want to ruin it in the first week lol.

Think ill have to have a little look in the manual before setting off then as when you ask these things at the dealers they never seem to know anything and will say boot it from the gate.

Cheers

I had a new Yamaha wr in 2013 and u had to not go over a certain amount of revs untill the first oil change after 1500 miles

They did a test on motor bikes a few years back and the one that had been run in properly had more bhp than the one that had been thrashed from the word go , I ran my bike is as it should so maybe take it easy for the first 1500 i'd say .

Just do what it says in the handbook, if your engine develops a serious fault and you haven't followed their procedure there's a good chance your warranty will be void. I'd put money on the ecu having datalogging so they can check

Agree entirely. I wouldn't risk it with any car no matter what the manufacturer says. Fifteen hundred miles of taking it relatively easy pays dividends further down the line in my book.

I think it's common sense tbh...

This "give it death bounce it off the limiter...kill the c*nt" mentality is just childish....

Wheres the harm in doing 1000miles normal driving?

A friend of mine bought himself one of those GT86 things brand new, he had it on the limiter sideways at the first roundabout!

cossynut2

Has he written it off yet as that is just stupid!

cossynut2

Agree with you, if the manufacturer says it needs to be run in ,do it as you could invalidate your warranty.
When I ran in my Cossy i stuck to around 3000 rpm which was still over 80mph
in 5th so you dont need to be crawling along at 40 or 50mph.

Cos500

it was normal driving, it had a change up light?

Im sure i was reading where someone about April time took their RS3 from the dealer and did a launch from the forecourt (cry)

Not much of a thing these days, but it won't cause any harm by doing it

You can't hit the limiter in it, so I wouldn't worry about running it in.

Adam-M

I don't get why you wouldn't need to run it in but if you went to a tuner right now to get an engine rebuilt then you'd need to run it in, so are the tuners behind the car manufacturers?

I'd do it out of principle tbh it's not as if your only going to be given the opportunity to drive it for 1000 miles Then hand it back

The running in process is done at the factory after the engine is built. By the time you get the car it's run in and already had an oil change.
Of course there is exceptions to the rule.

I got in my Focus and drove it like I drove any car. Took it in for an oil change at 6250 miles.
