Owner's manual slight confusion about engine break in period...

Some extra reading if you'd like:

It's just another point of view. I, personally, am not saying it is right or wrong. I simply don't have the experience.

It also says that before doing anything you should warm up your car for about 5 minutes. I think this is the only thing that everyone agrees on. =P

oh crap... in that case i've been doing it slightly wrong. I just wait until the rev drops then i slowly take off, not revving pass 2.5k through some small streets, my car warms up by the time i hit the main roads.

Yep thats exactly what ive been doing. 5 minutes seems like aaggeess... but its probably better during the break-in period Won't make a massive diff though, as long as you don't fang it when its cold lol

That should be fine. Just don't get on it till it's warmed up. The 5min mark is arbitrary. Obviously it the time required to warm everything up will be different depending on the ambient air temp. At 20F outside it will take much longer than 115F.

That's about -6C and 45C for everyone playing at home.

My apologies, and thanks. Sometimes I don't recognize where I wander in here. :happy0180:

i had quite a blast in the hills on the weekend while keeping it under 4k rpm. Its WOT all the way till 4k, change gear, WOT till 4k etc etc. On 500ish now, another 1000 to go :/

thats what I do

Just drive it normally, get up it, drive it normally. However you normally drive any other car.

The Porsche Boxster manual said not to warm it for 5 mins but rather drive it straight off.. obviously gently until up to temp ... could this be a boxer motor thing??

I've had a bunch of people tell me the same thing. My guess is it's to do with oil pressure and providing maximum lubrication - especially during warmup.

I'm actually curious about a technique I read about years ago which was basically getting the engine up to running temp then booting it. If I find it again I'll post up some links.

Edit: Here's the link http://www.mototuneusa.com/break_in_secrets.htm . Maybe it's a load of garbage like intake vortex generators and fuel line magnets etc. ... or not

Just follow the book if you are not able to decide. You will get 100 different opinions on the web and they all are probably right in their own way. Below is one I prefer

The first 100kms of any new engine is the most important stage of it's life, they way you use the rev range and load the engine will determine how good the piston & cylinders seal forever.The better the cylinders seal the more compression, therefore more power...

Here is a example,
Have you ever driven a very similar car, eg typical Holden Commodore that has been a one owner can in the family from brand new, always service & looked after but has ONLY been driven by an elderly driver, compared to the same model car from the rental or ex-police department and the drive completely different. (grandma never revved the engine over 2500rpm), but rentals or persuite cars get thrashed from day one. They go much better!!!!

Never baby the engine & stay at the same rpm for long periods,
always try to use the full rev range, & try not to red line or over-rev engine.

They say it is very important to change the engine oil after 100kms or so to get any metal particles or shavings out of engine, and replace with the same grade and viscosity oil that was originally in the engine. Do not use synthetic oils just yet.

hey guys, long time reader about this, but never expressed my question at all.

firstly, i do the same, i wait until the needle is below 1k before moving the car and I've never waited more than 3 minutes, minimum 1-2 mins...

my question is:

proficience, do you mean you put ur foot down on the accelerator on neutral? and hold it on 2.5k? until the engine is warmer sign returns to the middle? usually how long does it take? cuz I've never heard anyone doing this....in your view is this better? I'm asking why is it better because ........... - >

IM GETTING REALLY REALLY rough 2nd gear changes like going from 1st gear to 2nd gear during my first 5-10km or 10-15mins is really bad.....does your way in making the engine warmer correlate with heating up the gear box? because i find that after 5-10km, the longer you drive it, the easier it is to PUT 2nd gear into place...considering that i go from eastern suburbs to *** nearly everyday, i only enjoy like 5mins of fun time with the car, the first 10-15mins is hell lol...

No, I don't mean to hold your revs up in neutral, that's ridiculous and probably worse for the engine. I mean, until the needle in the oil temp guage reaches its 'normal' position, I try to keep it under 2.5k rpm max when driving. This reduces stress in the engine while its still not at 'warm' temp.

Do you have an auto box? I find the first 5 minutes are sometimes rougher as well (only sometimes ), but then it settles down nicely.
