Picking up my new i30N hatch in a few days and then driving it about 350km home. I’ve done a bit of research on the break in period, but wanted to get some thoughts here as well.

Everywhere says vary the speed, rpm’s, gears etc I can’t find much though on the intervals. For example, how long do you maintain the speed/rpm before altering? 3 mins? 5 mins? 20 mins? It just says not for long periods with no definition on what that is.

Also, some other makes say to keep the rpm 2-4k, but Hyundai say keep them under 3k. Keeping them under 3k, but not lugging doesn’t give much option room to drive the car!

It’s not made of cream cheese,you’ll be fine,just make sure it’s warmed up properly and keep under 4K for 1000km,no redlining and no full throttle.
If you’re on a long motorway trip just remember to go up and down the box At regular intervals.

Makes sense and that’s my understanding. Just trying to get a sense of how often to vary speed on the highway (which is where the trip will take place).
 
Don't over-think it. If in traffic just follow along and don't lug (I'd stay between 2 - 4K rpm) - on open fairly level road catch a gear or two every 10-20 minutes and accelerate to 4k, or the speed limit, then let it coast back down to cruising speed and upshift. You really can't hurt the engine/drivetrain as long as you drive "sanely".

Thanks, kinda what I had planned. Now just have to survive the next 5 days waiting to go pick it up!
 
Hi guys I am currently trying to run in a new i20N how many miles will I have to do before the car is considered run in. I have been told theses engine burn engine oil, up until the 4000mile mark. I am presuming that is the run in period am I right???
 
My i30N is about 44.000 km on clock
I drive it slowly each morning 10 km Downhill>Flat>Uphill and same way around to go back home.
I let it warm up till you hear the exhaust louder (1 min for cold,30-40 sec in warm season)
Each week checking the oil amount to prevent the engine to die on you (Since Turbo can eat oil when full throttle on not warm engine)
When warm don't be afraid to take her HARD as the Carbon build up can cause problemes later on.
Sometimes I do throttle it Hard when the engine oil is warm to mid on the Dash or when you see the Orange line around the RPM meter disappear then its ready to use much better.
But as I daily drive it,I shift above 2k or 2.5k and shift
Using the Rev Match button in Normal drive mode is also recommended in my use,just saves lots of energy by the Trans.
I am after all a former Car Mechanic and know my way around Cars especially around Turbo Charged (Old School).
 
1000km is the spoken minimum, we did 1000 then gently more rpm's each 500km. Ending up full range and load at 2000km, first oil change on 2300km. Now the N hasn't got nearly zero oil consumption, but it is pretty slow. Maybe due the less aggressive break-in period? Who knows 🧐

An engine that was build up new I did a 5000km period and it is very fine.

There are several methods and stories about break-in manners. You can't really tell which is the best, every engine type and materials could benefit more or less.

At least give the material some time to break in and set in, on comfortable temperatures for the material and less stress loads & rpm's.

As said above, just drive it like your off to shops/work and don't kick its arse and you will be fine.
 
Not really "break in" period for me(5000 km), but didn't find a better place to ask. Just did a 2200 km vacation trip, mostly european highways, 130-140 km/h, cruise control, AC, etc. Averaged 8.4 l/100 km. DCT mostly kept it in 8th gear, 2000+ rpm. I briefly used the paddle shifters from time to time, but even in 5th gear, rpm was not really very high. Did 10 hours drive with fuel, toilet, food stops, so I was pretty tired and tried to enjoy the comfort. Would've been better(any advantage?) to use manual mode and keep it for some/longer periods at 4000-5000 rpm, instead of mostly auto 8th gear? Is carbon build up influenced in any way by long highway relaxed trips?
