Wilson 4JR Oil

I know the manual calls for 10-10W oil for the oil pot. Can’t seem to find it anywhere. All I have is 10W-30. What oil are you guys using in these old Rockwell testers?

ISO 32 is SAE10w. Put this number in at AMZ: 'B07BQNC8T2' It's light compressor oil. SlientAire is another brand you can search at AMZ. It's 10w, also.

Lucas motorcycle fork oil, can be found in 10w. Got mine at O'reilly Auto.

My oil pot is a bit more than halfway full, so def need to top it off. Do I remove all the old oil and just replace with new? If so, does the oil pot come out to empty it or is it gonna be a pain?
