What I'm saying is that engines last longer and longer despite even

about. Both oils and engine manufacturing techniques - and or
materials - are improving all the time, so there really is no need to
change oil more frequently than the maker's recommendation.

You have to remember that makers have extended the service intervals to
appeal to the 'Fleet' / contract hire market, they don't actually care
what the mechanics are like post X [[1] mileage as the car will have
gone though the auction market by then in most cases.

In which case engines would be failing earlier than before due to oil
related problems. This simply *isn't* the case. They last longer than
ever. Failures like cambelts and head gaskets excepted.
Strange the way some think that oil changes are a major cost in a car but
ignore cambelt changes which in some cases can cost hundreds.

anything from 12k to 50k in most cases

The servicing costs over 50k miles is peanuts compared to the deprecation.
