Advice sourcing Mineral Way Oil ISO Grade 150 for my lathe

[Madhattan]

Thanks everyone for you responses and advice. My mill uses Mobil Vactra #2 and I can source that in one gallon containers from MSC Direct, McMaster-Carr, and Amazon. My shop isn't heated so the lower viscosity will benefit me in winter.

I use iso 68 way oil most of the year, and ISO 32 when the shop goes under 2 degrees C. I use about a quart a year, on 8 machines.
