I have an old Sullair tow behind screw compressor, powered by a John Deere diesel engine.
The compressor oil in it appears to be all dirty.
I have a can of 5 gallon of "Kaeser Sigma 460" screw compressor oil. Would such an oil work in this Sullair screw compressor? How specialized are those oils?
I would prefer not to spend money buying new screw compressor oil, it is expensive.
Thanks
