I have to chime in here -
First off, that's ugly... really ugly. I wonder if the guy was running with the oil cap off, or with no air filter.
That said, there are a few oil companies that spec a 20K mile oil change. Amsoil comes to mind. International Harvester 4300's have a factory oil change spec of 15K and believe me, diesels get dirtier than gas engines. With modern synthetic oils the days of the 3000 mile oil change are really over in most cases.

Supposedly AutoRX is supposed to work much slower and therefore be safer to the seals. Regardless of the choice, it is supposedly running, apparently pretty well, and the guy is extremely lucky it didn't do any damage.

They were concerned that ATF is too aggressive of a solvent and could cause microleaks in the gaskets.

Mixing a quart of ATF in with the engine oil and letting it idle for 10mins then flushing it out isn't going to cause any "microleaks" in the gaskets.

The OP on bimmerforums declined to answer someone's question regarding the reason for this occurrence which makes me worry that it might NOT have been a scientific experiment
Your engine oil is like your underwear: it's going to get dirty before it gets "worn out" and that's why you change it... the difference is you can't put your engine oil in a washing machine.

they seriously say 15K OR 1 year? That makes even less sense, theres nothing at all about oil, especially synthetic, that makes it go bad in a year.
So if I have a BMW that put a 2K miles on in one year its time for a change but if I have a BMW that I put 12K miles on in 2 months Im good for another 10 months or 3K miles??
