Any running in required for new D4?

[mojo]

So we picked up our D4 this morning. I'm just wondering if I should be driving it any particular way while the engine is "run in"? Any do's or don'ts?

What does the hand book say - I suspect nothing as technically the engine is already run in. However if it was my vehicle I would just use the vehicle normally - no unduly heavy loads and likewise nothing at the other end of the scale - driving that exercises a wide but not extreme throttle settings.

Mojo, congrats on the purchase of a lovely car.
No not necessary, but if you do not want it to burn oil get it properly warm and give it some heavy throttle up a few hills without going to the redline. This will confirm the rings are properly seated, but DO NOT drive at constant revs and low load on a freeway for any length of time as it will glaze the bore.
I took mine for a drive around the mountains at the back of Coffs and have just turned over 38,000 in 12 months and it goes nicely and does not have an oil consumption problem. Some will say drive it like you stole it.
It is such a fantastic car and I simply love driving it and I am sure you will too.

Haven't had a chance to read the handbook yet, I'll take a gander tonight.

Plane Fixer, interesting what you say about not running at constant revs on the freeway. To me, that means don't use the cruise control, particularly if running on a flat stretch of road. I remember when we bought our Tdi VW Tiguan, I was advised against using the cruise control for any length of time for the first several thousand k's.

It certainly is nice to drive - just a wee bit different to our Defender!

Not necessarily true; I used the CC between Syd-Mel and back, but used the Command Shift on a regular basis to drop down to a lower gear, hence higher rpm.

Does the same job.

Don't thrash it, but make it work.

I didn't tow for 1,500 km but other than that its driven normally.

Accelerate in a varied manner, sometimes soft, other times with a bit of vigor.

An engine that is used (not abused) generally runs better.

The same run in principle that I have applied to my cars over the past 10 years.

Good advice.

Much nicer than my performance car run ins

- Bed cam in at fast idle.
- Run up in Dyno to set tune and mix
- Remove from dyno and fit "old" Tyres
- Pull onto road in industrial area and "light it up" for 5 minutes

Some of the strongest engines I built were bedded in like this....

5 minutes is a long time to light it up,you wouldn't wanna stick around for too long after that

All my new vehicles, i have driven lightly for the first thousand k's or so,including trying not to be hard on the brakes,then drive them normally,with a bit of right foot punch every so often.Never had one use oil ever,or for that matter any engine issues.

Thanks for all the advice guys.
