Probably not though... Modern engine could actually be harmed with too frequent oil changes due to the volatility of oils. You get burn off in new oil of various hydrocarbons that can clog up a lot of things. My guess is that you're unlikely to get issues either way but I think BMWs system is actually kind of smart - essentially the more motorway type relaxed driving you do, the less oil needs to be changed often. This makes good sense and can be calculated from mileage, cold/hot cycles etc... They know this info and give you guidance based on that rather than you guessing on your usage like most manufacturers.
This has been my thoughts for a while too but regularly when I speak to someone who has had an E46 M3 or E9x M3 or even an E60 M5 I am told time and time again that oil changes should be done mid service interval, so every 6-7k miles instead of the BMW stated interval of up to 15k miles (or less depending driving style). The bulk of this notion was to prolong rod bearing shell lifespan but the reality is that even BMW acknowledge that shells should be replaced from ~80k miles and the vast majority of failures are in the 80k to 100k mile range although it does totally depend on the kind of life the engine has been put through by its often many owners.
As some will know from the thread here, my original S54 had bearing shell failure happened at 114k miles. There were no symptoms before this point, was just driving off the motorway then suddenly loud ticking. Again online people said you often hear symptoms beforehand but not so in my case. The S54 is a rattly engine by nature, pop the hood and you'd think something was broken inside but this is how it is.
I guess what you say makes perfect sense. BMW's numbers are sound. It is a bunch of umbers derived from millions of £ in R&D and long term testing. Bearing shells are a wear and tear item and should absolutely be replaced. Prolonging their life beyond 100k miles is a negative effort. Preventative maintenance and mechanical sympathy is the key here with stuff like this. Let the fluids reach optimum temps before going beyond 2500rpm and accelerate smoothly as well. You get the idea.
There’s a guy round the corner from me who will clock anything with a digital odometer for around £20. His customers seem to generally own modern BMWs / Audis etc which have been used for long distance work trips. He regularly takes over 100k miles off, and the smarter owners will go to him every 6/12 months before the service so all the records look like they match up, with the car doing 4-5k miles per year instead of 30k. As a buyer it’d be almost impossible to spot unless you had dealer level equipment.
Typically there are very easy tells for a car's mileage based on its visual condition inside and out. Very very few people who clock their cars will be the same type of people who meticulously maintain the interiors as well. A clocked car that has had 30k miles+ shaved off it would stand out when you sit and look around the cabin.
