Thank you, Richard. Bookmarked.
But in the meantime, if anyone needs 705 equivalent the prices at the site above are better. We'll see how it holds up.
(edit) ordered the oil yesterday morning, it was delivered today. Will test this week-end.

I've heard of somebody making DIY diffpump oil (was ambiguous whether silicone or hydrocarbon), but I really cannot imagine that being a good idea except for learning about where apeizon and the like come from.
