There are a lot out there, you can look up the NSF listing for brands listed. It is basically a group II or better with non toxic additives. In Bolivia I sell a lot of ISO 15 for soybean oil extraction where no additives are used, and some 32, 46, and 100 VG for sewing bags of sugar and flower, air compressors at Coke, and a few other uses like gear boxes over mixing tanks. Also a drip-resistant (tacky) ISO 150 for overhead rails in meat plants and chains in heat shrink packaging equipment.
Chevron also sells a pretty complete line, and should be available almost everywhere. Look for their FM oils and greases.
