Has anyone used Duralube in the wasserboxer or recommends it.

A friend just told me about his motorcycle which has an aluminum engine
which had duralube in it. his oil plug was not tight and fell off on the
freeway. He checks his oil after every long trip he ways. No oil. He drove
130 miles home without damage to this engine.

Sounds like an infomercial but this guy I trust and he is a trivia buff.
Seems to know a lot about the stuff.
