That is NOT way oil, and is designed for an entirely different application. Engine oils are for hydrodynamic bearings, where the spinning journal provides the shearing force that floats it.
The ways of a machine tool move MUCH too slowly to produce this force, so they depend on an intricate balance of viscosity and surface area. All the machine tool dealers carry some brand of way oil in 1 Gal. bottles. The oil for a Bridgeport should be ISO VG (viscosity grade) 68, which is approximately SAE 20. but, if you FEEL the way oil, you will immediately see there is something different, it is a LOT "stickier" that engine oils, and will remind you of a gear oil. That is what keeps it in place on the ways, where the SAE 20 will film off and end up on the floor overnight, the way oil will take a MONTH to get there.
