Oil leaks

Is there any chance of Blue Devil causing harm to the engine?
I have no idea. I’ve only used the German product I linked to. Ive done about 80k miles in the Toyota with no adverse effects. And I’ve used it on two other Italian cars (my 850 doesn’t need it) so I’m comfortable with that.

Thank you for relying. I did not see a link. Can you tell me what product you used?
