Best/proper way to run in your engine?

[joey_kev]

Hi,

Just bought myself a new accord, its only 17km on the clock now and I know how you drive in the first few k's are very crucial for its long term.

Any input?

How long should I warm up the engine first thing in the morning before I drive off?

Drive it hard. Don't redline it, just load up the engine. For example 60km/hr 4th gear plant the foot till 80-90km/hr

Let it warm up and then you can drive it hard, that's the same on a new or old motor. I run them easy for the first 300-500 miles then harder for the next 1500 miles. Once I hit 1700-2k miles I drive like I normally would. Do oil changes at the first 250 miles, then 500 miles later, then 1k miles later, then 2k miles later, then you can start doing them every 3k or 3 months or what ever you want.

That is like the worst thing you can do on a new engine.

Drive it how you normally would, but avoid going too high in the RPM range. Also don't do hard launches or anything like that...

What you want to do more often than usual though, is to let the car engine brake (if it's manual)... i.e. you're 100m off the traffic lights and they're red... drop it down a gear or two (depending on your speed) and let the revs/momentum of the engine/tyres slow the car down, this helps the ring to seal as there is load on the engine but it is not at high RPM.

So yeah, use the available rev range - up to a certain point... for my car when I was running it in, I didn't go above 5000RPM (H22A) - but I varied the load on the engine... quick acceleration in low gears (2nd/3rd) up to that 5000RPM... lots of engine braking when going down hills or coming up to traffic lights, etc...

Use it, don't abuse it.

It's really a grey area...

Some say baby it
Some say thrash it

not sure about breaking in a new engine but try and get the oil and filter changed at the 1,000km/1 month service if you are going to break it in hard (imo)

. Do oil changes at the first 250 miles, then 500 miles later, then 1k miles later, then 2k miles later, then you can start doing them every 3k or 3 months or what ever you want.

for all current AUDM honda's they have additives in the oil from the factory and Honda actually recommends AGAINST any oil changes until the 10,000km mark.

the Euro still has the oil change at 1000km or 1 month (whatever comes first)

drive it like its stolen.. ahahah kidding..

dont thrash it in 1st and 2nd... give it abit in 3rd
redline is ok.. but dont WOT.. never WOT

I would do a hell alot of 3rd gear engine brakes from high revs all night.

[ACTI0NMAN-1]

as blitz says, also a bit of loading like accelarating in higher gears.

Hi Guys

I ran-in my recently rebuilt D16Y1 SOHC VTec using the hard method as per the instructions here::

http://www.mototuneusa.com/break_in_secrets.htm

She’s now done about 10,000Km since the re-build and she hasn't missed a beat, plus I red line her daily

Believe what you want but the article made sense to me, hence the reason I decided to try it..

i agree...its a very grey area ?

there was a thread a while on this

as stated earlier
some people say baby it for first few thousand km's
others say gun it from start.
