Just to add some fuel to the fire, I don't use it nor would I ever use it, but I found it rather interesting that new BMWs use Castrol. My friend's M5 with the high tech V10 has the Castrol only stamped on the oil cap. Their oil change intervals are in the 15,000 mile range too.
I would love to see a pic of one of those engines after a few years.
You mean these


I found the real story on this BMW. He went 60K miles between oil changes. This sludge problem has NOTHING to do with the scheduled OCIs and oil BMW recommends. Just to set the record straight.

Hi everyone,
This is my first post on the forum and I hope I am bringing something of interest. I'm a member of the toyota supra community and this thread was brought to my attention. I've read a lot on this forum, but have never posted.
I had a look around on BITOG, and didn't see this posted. forgive me if it has been.
Anyhow, this is NOT my car and I do not know the people involved. This thing has gone 60,000miles without any filter or oil changes. sounds like this all started with a malfunctioning vanos...and I think it's clear to see why it wasn't working!
They have removed a lot of sludge by hand, and intend to run a couple cycles of autoRX through it. I wonder if it's up to the task??
Fingers crossed oil passeges aren't plugged while cleaning..
