I had this same problem, hard to read, and as others have said here, the stick would catch oil on the tube as I put it in... very frustrating. It would sometimes take me 15 to 20 minutes til I could get a read I was confident was ok to fly with, I even used the method of laying read end on a clean rag or paper, still with inconsistent results.
So I called Jabiru and got a new dipstick that has 3 holes on the read section, which catches oil if it is at the right level, and it has a zig zag part just above the read section so you can guide the dipstick down the tube without getting the read section contaminated.
