I have a Gast vacuum pump with a small glass jar attached that has oil in it. I have not been using this pump yet - but want to. But I do not know what kind of oil to use in this small glass jar. Anyone know?
I also have another Gast vacuum pump with out the oil jar. Is it better to use the pump with the oil jar or the pump without?
Thanks
Hugh
