What car u drive??? Usually most car manuals won't recommend more than 110km/h.

Also, you can maybe run-in on a Dyno, the sosphicated way....just make sure u don't end up like this guy...

If Auto trans how to break in...?

either use "P" and rev engine when under stationary condition or use "2" to rev when low speed...

okie, thanks~~

yes...u need to break in
auto or manual is the same technique
drive it like u stole it

for me, rev gradually to higher rpm, do it for each gear

i did for my car... each gear rev till 4k rpm at tolls, traffic lights but kept it under 120km/h

Simple,

To break-in the new engine, just drive as you will normally drive lah..
If you are a fast and furious driver, then drive it hard.
If you are a slow and steady driver, then drive it slow and steady.

No need to drive it hard but in actual fact you will only drive it slow.
No need to be so gentle if you like to press the pedal to the metal.

New car and still in warranty right? then by all means drive it hard.. any problems just get back to SC and claim.. hahahha.

Drive it like how you want it. Just don't crash it or crash into something else not belonging to you.

depend on what TS believe... if u think break-in is necessary, go ahead...

for me, i didnt do any break-in and low rev as possible on my myvi to save fuel, the best FC i can get is about 19km/L for the first few months... but now average can get 17km/L due to heavy foot bit... hence no engine failure issues within 4.5 years with my nanny driving style without proper engine break-in...

still thinking n not decide yet either to do the break-in or..

Just keep the rev to cover most of the RPM range. This should set your piston ring nicely.

actually for new car its better to drive the car hard
but not really hard like redline
cuz the oil pan seal gasket seal, piston ring all those need to rev it for it to settle in or for it to be more tighten or something like that

semua suruh push the car ..ikut hati masing2..maybe its more like do you need to warm up engine before you jalan..

some say no need to warm up ..some say need to warm up 2min..

omg, this is one class debate. Never-ending discussion on this. The two school of thoughts swears by their own style. As for myself, i drove gently before 1st service

I know someone who swears by pushing his car to the redline
