How to accelerate new car?

[mikhaelnen]

Hi, all forum members

I'm getting my new AUTO CU2 next Tuesday, would like to know some advice of how to accelerate the new car (the first 1000km) for it's best performance (not only engine, but also breaking, gear etc.) in the long run.

Your advice is much appreciated. Thanks.

Drive it gently on first 8 mins untill everything is warmed up.
After that progressively increase the throttle to full.
Avoid long constant rpm if you can. It means no freeway driving.

Thanks, twing. I am going to the south coast a week later after the delivery, how can i drive on the freeway without long constant rpm? So, no cruise speed at all?

Full throttle on 1st and 2nd gear, before 1000km?

[spastic]

no he means constantly sitting on same speed.

the only way to avoid this is to either avoid freways or to vary ur speed say do 90-100 drop to 90 etc.

No problem on full throttle on 1st and 2nd gear as long as the car oil is warmed up. Note that it's the car oil temperature that's important. The temperature displayed on ur dashboard is the coolant temperature. Oil should be warm enough after 10-20 km drive.
It's better on the 2nd gear because it's more pressure loaded to the piston ring.
Please do it on a safe environment.. it's a new car and it takes sometimes to be accustomed in a new ride.
Full throttle is NOT a must.. take it to the level you are confidence in.

ey twing why not constant rpm in new cars?

ey twing why not constant rpm in new cars?

Constant RPM means very little load which causes the piston rings to not seal as well as if you drove it with varying RPM and load during run in. As a result, you can get an engine with no apparent problems but have lower compression test results compared to another engine of similar age.

This is how I run in my engine. http://www.mototuneusa.com/break_in_secrets.htm

There is other threads asking the same question.

Maybe should add this to noob sticky..
errrrr... but people won't use search anyway. Oh well, we can just do so much.

Hi, I actually visited the above Jazz forum before starting this thread. Because I feel that the engine capacity is different, so should have a different approach of optimizing the engine performance and other parts of the car.

Anyway, thanks.

+1 to a hard run in, should give you better fuel efficiency later on as well

slip in a few redline changes if you want it to perform well. Try to constantly revs. Ran 2 identical work cars in. One got putted around in the other got a bit of a kick in the pants from new and ran much better. More responsive.

I did this with Mum's CL9 euro. 110,000kms later and still runs beautifully. It actually goes better then my CL9.

Drive it like you stole it!

exactly people are scared to with a new car though....strange. Engine is half run in from the factory so its not the same deal as running in a freshly rebuilt engine.

Or the car's ECU learned the lead-foot driving style for that car and simply responds. But I too think that once the engine is warm, it needs to be loaded-up.

[mikhaelnen]

How to practically/effectively warm up the engine before driving it hard? Will the warm up period wear out the ring as well?
Well, how long usually is the warm up period? How many KM should be run?

Sorry, newbie

hmm you know with the new car u meant to break in the engine first just follow ur log book :D and drive it normally without trashing it.
