Ok, I give up. I can't find any way to buy way oil on Vancouver Island. KBC is back-ordered.
Here is Way Oil on Amazon.
Mobil - 105480 Vactra No. 2, Way Oil, 5 gal, ISO 68

At $433 + 80 shipping + tax, it's not cheap but you do get a lot of it. I got what I have from Grizzly in the USA and had it delivered to a friend in Michigan.
I bet you could also drop into a few local machine shops and buy just a few litres.
I believe that the primary additive that is in way oil is a sticker that make the oil stay on the surface instead of slowly running off. I think that additive is worth paying for. I wouldn't use a straight oil without it unless I had no choice and even then only temporarily.
Basically, I think that the heart and soul of a lathe or a mill is its ways and its spindle. I believe these two elements especially need all the love and care I can give them, so I would not compromise on the oil I used. That's my view of it anyway.
