Manufacturers make money on faults developing outside warranty but it costs them inside it.They work out the probable fail rates and stretch servicing as much as they can,to make running costs meet other manufacturers costs so when you choose a vehicle and take service costs into consideration,their cars remain a viable option.
If i were to buy a new car with the intention of keeping it years outside warranty i would be doing regular oil changes,oil costs very little but its the life blood of any engine.You dont need to change the filter if doing interim oil changes just the oil.
With that said,engine parts are made nowadays to much better tolerances and only a fool would run an engine in slowly other than a few miles especially a diesel which 20 mile aside want driving normally and occasionally using more briskly.Revs were never the issue although manuals keep it simple for average folk,its excessive heat you dont want and that can be gained at all revs.
So to answer your question,if keeping it in warrenty before binning it,no,if intending to keep it long term i would.
