The basics still apply and most manufactures do have a recommended driving method listed in the hand book;
*Drive moderately at different speeds and dont do large long kms at highway speed for that typically first 1500kms or so.
*Keep rpm to a limit of about 3000rpm (so just under that sweet gear change point for a Defender TDCi) but dont labour the engine, so dont use 5th in a 80kmph zone, 4th is a better choice, dont use 6th for freeway 100kmph, 5th is a better choice.
*Dont sit there is the morning with the vehicle idling to "warm it up", it doesnt, it will get to correct operating temp with light acceleration.
*If you want to do the occasional high rpm to see how it accelerates, do so when its at normal operating temp.
*Light to moderate driving for that for 1500kms will also allow other components to bed in correctly such as brakes.
*Check under bonnet fluid levels weekly.
*Do an oil change at prolly 5000kms, why not the Ol 1000kms first oil change? As already mentioned build quality of engines and oil quality is far better than it was 30 or 40 years ago. But there will still be metal particles from that initial running, it would prolly also be fine to extend that first change to 10,000kms giving you any easy to remember engine oil change interval every 10K.
*For a Defender TDCi (puma) change out all driveline fluid levels round that 30,000kms, you will find the Transfer case and especially the diff oils, will be black and metal loaded.
