I have been finding a considerable amount of IDGs (Integrated Drive Generators) with low oil qty on the engines. No oil visible in the sight glass. Please see attached pictures of various aircraft. No leaks have been noticed after accomplishing a 5 minute idle run; so; I am not sure what is going on. We need to be serviced or checking the IDGs more often.
Technician reported IDG oil level was low and after servicing and a 5 minute idle run; no leak was noted. Technician also reported other instances of this issue.
