Not wishing to lob hand grenades, but the spec of the oil is wierd, GL-4 is a rating for gear oil and API FS is an obsolete rating, no longer used, and I also notice it hasn't got an SAE rating, which I presume means the SAE haven't tested it, which then leads me believe its no better or worse than Minispares blue bottle stuff and probably the same.

I'm sure it'll be ok, and that they'll respond to any specific technical queries. Fair dues to the MCR for getting involved.
