ATF and Marvel Mystery Oil both have solvent properties, but modern oils now
have high detergent capability to prevent sludge buildup.

I've tried MMO at the recommended 25% in both my '84 and '85 to no avail.
They also thin the oil. I wouldn't know how much ATF to use, but don't
bother with either of them.

In the '80s manufacturers built engines (and cars) for a 100k mile lifetime,
and we are pushing these obsolete designs way past that.  It's just part of
the wear cycle, and my clattering '84 went 250k and was still running fine
when I replaced the engine (just for fun and that was a mistake).  It had
valve clatter for most of its life.

As long as it goes away after a few miles you are good to go.

Anybody try a little ATF in their oil?  That's the prescribed method to
quite them down in other vehicles.
