lookie what i found...there was a discussion on this board about it. see:
http://www.quiltingboard.com/main-f1...re-t42275.html i also searched the internet for it. i haven't looked at everything, but so far, i have not seen a reason to buy it except that it is the juki brand. also, there is a #2, and i don't know what the difference. you might want to check with the juki dealer or a sewing machine repair shop to see what they have to say about it. i would figure out why i would need to use that particular oil before i tried something else. could the juki oil be synthetic or mineral oil or other kind of oil? i don't know. it is best to check with someone who knows more about sewing machines.
