Break in, hard or easy

[Ray_mon]

Im confused atm, my dc5 has done about 100km.

I've been taking it rather easy just as the manual says. However i've heard of people saying to break in hard, it will make for a better engine in the future, and plus the k20 motor was built so u can redline it straight from the dealership.

Is this right or should i stay on the safe side and go slow

DC5 Lux, drive it normally.
The k20 that they are referring to is the k20a2.

Nice and slow mate,
100km is next to nothing.
Give it at least a couple thousand.

And like Aaron said, ur K20 is different to the DC5R.

i thought it was for the first 1000km. mmm... if ur engine is not the k20a2 then yeh better to be on safe side than regret in the end and drive smoothly.

best thing to do is do high way driving. it puts less strain on your engine than if you were doing city driving, even if you drive nice and smoth. you'll also rack up the kms faster yo.

i thought it would be best to drive the car reasonably heard?

I remember reading an article which said that the common practice of driving slow in order to allow the seals in the engine (pistons etc) seal properly. The article stated however that driving hard within the bedding in period caused the seals to seal 'better'. Apparently after 100k kms, the difference between stock engines, one bedded in hard, the other soft were around 10-15kw.

imho, makes sense to drive the engine hard.

Here we go again another never ending thread with everybody's opinion on break in.

Yup and I'll say what I always say... 100 miles nice and easy then slam that throtle to the floor and make her work! Once the rings break in there really isn't much to worry about except the bearings and those break in fast too. Rings break in within the first 20-45 minutes the motor is running, about the time the smoke stops puking out the tail pipes!

usually it's the first 1000km you have take it easy....

Sounds like common sense to me.

If all fails, you do have warranty.

Drive it slow initially - the piston rings wont seat properly and the car will stay slow
Drive it normally initially - it will stay normal
Thrash it initially - it may cause excess wear and will become slow


Well thats my Theory


Here's an interesting Break-In article~

You're not meant to thrash it. Even mototune says not to trash it. Just 3-4 2nd/3rd gear runs up to 5000, 6000 and then 7000rpm. That's all. After those few minutes, you run your car in GENTLY for the remainder of the 1000km.
