Go here: https://filterproducts.com/lubricants/l ... reference/

And enter Rotair.

Looks like ISO 46 Compressor oil is what you need.
Options:
You can buy mineral based ISO 46 screw compressor oil
You can buy synthetic based ISO 46 screw compressor oil. Change intervals are about double of mineral oils, and they also prolong the life of the oil separator.
You could use a ISO AW46 hydraulic oil. Cheaper, but less anti-wear additives, and they tend to foam a bit more. (usually not a problem, unless the compressor cycles on & off frequently)

Many screw compressors (I' have been around lots, but not Rollair brand) used Type A ATF, hydraulic oils, and even light viscosity motor oils. They really aren't that picky.
Synthetic, in my opinion, is the way to go. Longer service interval, and they tend not to plug up the separator...which is spendy.
Don't forget to change the oil filter. ;)

When in doubt, check with your Rollair dealer, but they will no doubt push the genuine certified will change your life Rollair branded oil. (That they buy from someone like Chevron) :)
