Today I went through the frustrating and infuriating experience of changing the differential oil in my '31 Model A. The old oil was, of course, easy to get out, but getting the new stuff back in was another matter entirely. After experimenting with three different arrangements of tubes and funnels, one of which dumped a cup of the thick oil on my head, I finally arrived at a solution with a small funnel and a short length of tube that barely worked, taking a very long time to finish the job. The tube was just small enough to fit into the filler hole, but too small for that thick oil to flow at more than a trickle. But at least it's finished.

I know there's got to be a better way to do this. What works for you?
