Gronk,
I'll start the first response (hehehe). I don't know about Jeeps, in particular, but I dumped the big trailer (around 3T) on the back of my 1HZ 100series when it had 28km (that's not a typo) on the clock. No such luxury as a run in time for this car, it turned out to be OK and I am aware of many truck drivers who put their trailers on with very low km's and just drive normal with no side effects. If you have to, it can be done.

Silvercherokee,

well done on a nice purchase, get out there and enjoy it for what it can do and where it can take you.

Regards, Trevor.

I'm with you here Trevor.

I've had better luck, over the lifetime of a car, with cars that I've driven normally since day one. The matallurgy the manufacturers use these days is very high-tech, so what we used to call a "running-in" period is pretty much null and void these days.

Running-in was a period where poorly-matched, standardised cylinder liners, rings, pistons, big & small end bearings, cranks, journals, etc, etc were asked to get along harshly until all the rough bits were graunched off and disposed of in the first couple of oil changes.

These days the production tolerances are so high that very little actually wears over time if oil changes are maintained.

It IS a Jeep...? don't tell me I just brought a bleep box, I drove a few cars above it in price range...like the new diesel Pathfider but the gearbox was increadibly sloppy and drove some cheapies as well, but this suited me for the money and drove well and felt sturdy
Does anyone else have any opinions good or bad about the Jeep, the diesel got rave reveiws from various sources.

The "running in" period that I was referring to was the point at which you get the best fuel economy. I agree that the metalurgy and manufacturing techniques have improved to the point at which the "careful driving" stage is minimal these days.
