Tips for breaking in a brand new engine?

[Maz]

Queanbeyan/Canberra:
Around the ACT I think the Canberra to Batemans Bay drive & return is choice. If times permits – Canberra – Batemans Bay – Bega – Canberra – loop would be a good drive for a break in drive. Plenty of ascents & descents for the motor to load & unload with a big hill climb up the Clyde Mountain (or Brown Mountain if including Bega loop).

Thanks for the detailed response WJ - appreciate your time.

Coolant Pump (EA888 motor):

The thermostat begins to open at 95°C and is fully open at 105°C on the EA888 – TSI motor in the Mark 6 Golf GTI.


This implies that the Mark 6 GTI motor oil temp sweet spot is between 95 - 105 degrees Celsius. Any less than 95 degrees and she isn’t quite warm enough; any more than 105 degrees has a fair degree of friction/load happening in the motor.


Best time to boost up the turbo is a bit like asking how long a piece of string is. At the very earliest: 1500km. On the conservative side: 15,000km or after first service going from the mineral based oil to super slippery synthetic oil.


Volkswagen builds & tunes motors with a degree of margin regarding reliability. No doubt increasing the boost levels reduces that margin; But by how much? Again, it’s a bit like asking: How long is a piece of string? Biggest factor for motor reliability & longevity is most likely condition(s) of use and driving style.

Sorry to revive this old chestnut, however I've had a good look but I cannot find anything in the owner's manual on running in the engine.

Can anyone point me to the correct page?

Look in index at back of owners manual, under "R" for running in......thats where my info is

Cheers for that, page 263.

Only driven the GTI several times in metro city traffic (don’t count Canberra/Queanbeyan as city commuting despite what locals think about traffic jams in the National Capital). Not surprised to see that oil temps hover around 99-104 degrees on a winter’s day while driving around the CBD of Sydney in very slow going traffic. Temps out on the open freeway hover around 96-100 degrees most of the time – the difference being that extra-urban driving puts a lot more load and air cooling on the motor – city commuting just has the piston rings slapping around and not expanding to mate with the bore sufficiently so. The Mark 6 GTI does have an oil cooler that cools the oil for the motor and turbo bearings.

Fourth drive from Sydney South – Wollongong via freeway - up Macquarie’s Pass mountain climb – Bowral – Picton Road to base of Mount Ousley for return freeway journey looping back to Sydney and covering @ 250km has me thinking that the almost 2 month old GTI has hit a plateau in terms of breaking in the motor. Now revving the motor up to 5,000rpm with the paddles in DSG manual mode on some of the hill climbs with similar ambient temps as the prior 3rd Kangaroo Valley climb has oil temps rising and settling to same temps as on the previous occasion when revving the motor up to 4,500rpm: 90 degrees coming down Mt Ousley – 107 degrees with a short spike up to 109 degrees nearing the top of the ascent.

Hill climbs for breaking in the motor are great imo – 10-20min ascent with very light, very slow and no more than half deep depression of throttle application has plenty of load & friction on the motor, heating things up and expanding motor components together.

In contrast to the Kangaroo Valley hill climb – a drive up and down Mount Panorama, Bathurst had oil temps only climbing up to 102 degrees. Oil temps suggest it was time to try out ‘S’ mode in the DSG transmission (exciting ... the GTI does have 4,500km on the odometer). Looking to now cover the last 1,500rpm -2,000rpm from 4,000rpm to 6,000rpm to complete the mating process between the piston rings and bore.

DSG in Sport mode proves to up-shift gears quite a bit earlier than the old MKV GTI. The older version MKV DSG would hold gears forever and a day. Also impressive was the lack of wheel spin from down low when pulling out onto the Hume Highway from a stationary position at a T-junction B-grade roadway. At times, it feels like the EDL/XDS electronic diff is slowing things down to prevent wheel spin, while at the same time making the power application more usable in terms of moving forward at a more pronounced rate.

The break-in process so far has been a success in that absolutely no oil has been consumed in 4,500km.

Great read as usual WJ.

I can't believe how patient you have been to go 4500 km without using the 'S' mode at all.

+1. Come on WJ, time to open up the taps!

According to the manual, the run-in period is 1500km.

I had the best of intentions for my run-in period, using a method not dissimilar to yours. But the GTI's been too much fun for me to hold off all the time, and my car's seen 4,500rpm on a few occasions thus far, and 5,000rpm once. The car's done just over 2,000km.

I'm now driving pretty much as I normally would from a torque application perspective (so not taking it easy), but not flooring it, and keeping the revs below 4,000 under most all circumstances.

The vast majority of my driving is in metro areas (albeit faster-flowing ones), but I am careful to warm the engine gently and not let it get hotter than 100 degrees or so under those conditions. My car's also seen 106-109 degrees a couple of times on more aggressive hillclimb drives.

I'm seeing a small amount of oil use - when the car was brand spankers the level was at the top end of the roughly-graded section of the dipstick; it's now about 1/3 up that same section. Not sure how much oil this translates to, but it's still comfortably above min.

the length of the crosshatched section is approx 1litre. so you are about 300ml down at a guess.
