When the replacement arrived today, I opened the one-page 'User Manual',
that is in French only. It states that the gun is to be used only with
grease, and that anything else, such as liquids, are no good. But the
Amazon page from which I ordered it clearly said that it was an Oil
Gun, I took a snapshot just in case.

Here's the page:

Cogex seem to be French, and searching that part number comes up with
"Graisse", not "Huile". I think this could be an Amazon cockup.
