*Respectfully means letting everything get up to temperature.
With any 4x4 vehicle, the worst thing you can do is drive at a constant speed on the motorway for ages. That creates an uneven wear pattern in the ring & pinion sets. Varying your speed avoids this.
Thanks you 2. Now........ that is interesting! Conflicting advice always intrigues me. Decisions decisions. To give it some, or not to give it some, now that is the question. Mmmhhhhh???

Yes, but to be clear neither he nor I are advocating thrashing anything. We're both strong advocates for the concept of mechanical sympathy. His perspective was that pootling about everywhere like an old lady with blue hair leads to a vehicle with stunted performance.

I basically drove it gently for the first 1200 miles not really exceeding 4000 rpm. Between 1200 and 2500 miles I gradually started accelerating a little harder and taking the revs higher though not sustaining high revs for any length of time. All through that period the engine has felt very tight. I am now at 3200 miles and the engine is feeling a lot better, free reving and sounds less harsh.
So I now drive it basically ‘normally’.
