    Anyone here ever used this stuff? My grinder tag specifies it for way oil but I can't find any reference to it. It's obviously obsolete but I thought there'd at least be a datasheet so I can match it to a modern equivalent.

    Thanks for that. The grinder has an odd system where you traverse the table to one end then supposedly use a can to pump oil into a long trough above the ways, then it trickles along and down a weep hole. I'm worried that if I use my lathe way lube which is quite heavy, it might not travel fast or far enough.

    Well, I got a reply back from Castrol tech support with a very surprising reply:

    You might be able to get ISO VG10 in smaller quantities from the likes of Smith and Allan

    I sent a follow-up asking if the ZA spec oil came in any other viscosities, just in case. The reply was that ZA is 10 weight but he agreed that it was unusual for a slideway.

    I think I'll get the 32 I can always thin it out a bit.

    Possibly to counteract the light floating table

    Could be, it really doesn't weigh much. Perhaps I will try it on ISO10 and see how it behaves.

    Slideway oil is sticky so my only concern with using 10sae hydraulic oil is ‘drying out ‘and gouling . I think Id rather use 26 hyd oil
