Take a deep breath . . .
Better?
As you will note - perhaps - my sentence included the modifying phrase "within reason." I readily acknowledge that an extreme position on either end is unwise.
Now, relying upon the lead article you cited, we find in the synopsis:
"The composition of tribochemical films formed on the surface with the 3000 mile drain interval is similar to that formed with the 12000 mile drain interval as seen before."
There are many other similar nuggets to be had leading inexorably to the conclusion - it really does not matter what you do, within reason.
The bottom line remains that this is a silly topic to worry, argue and fuss about; your car's engine is going to be perfectly happy with 3,000 mile oil changes; 7,500 mile oil changes; 12,000 mile oil changes, etc.
Amusingly, rare is even the anecdotal story revealing the horrors of too frequent oil changes or too few, coupled with causally related engine failure.
And no, BMW is not going to take your warranty away if you change your oil "too frequently."
