Running-in
 
Is 1000 kms enough for running in a new Pajero? I think the book says 1500 kms but I am itching to drive "normally". The sales person said to keep under 2000 rpm during running-in and that is what I have done.

You can drive 'normally' from day one.

Salespeople don't have a clue.

The 1500 is more for doing the first service this is because factory engines typically run diffrent addatives to help engine run in from new. The idea is for you to drive it normally (traffic, highway, etc) and not flog it. The idea of under 2000rpm or don't do 100km/h would have ben good advise in 1960. Manufacturing techniques and metallurgy have moved on.

Forget the salesman - what does the Owner's Manual say?

With modern engine manufacturing, if it hasn't blown up by the time it hits the showroom, it's good to go.

I've read a few articles that suggest you're better off "running in hard" - use power to produce high combustion chamber pressures, to ensure rings bed in properly. Psychologically, it's hard for most of us to do with a brand new car, but now that you're past the "early failure" window (manufacturing defects) don't be afraid to use some pedal. If it's going to break under load, find out sooner rather than later.

Drive it 'normally', put it under load and without load, run it through the rev range. Just don't drive it at the same revs, such as down a freeway yet.

Mate is a GM of a MM dealership = engine assemblies are bench tested and run in prior to assembly into rolling chasis...

Just took it a bit easy the first tank and drove normally including a bit of a run through the dunes last week in MY 19 NX using 4H 4HLC and 4LLC. Just cruised up the highway 400km mostly 110km and achieved 12.1L p. 100km. Tank reading bit over half.

Cheers
Eski
