Sawdust as Oil Dry

I use my garage for more uses than storing motorcycles and tinkering with contraptions. I also do a small amount of woodworking, mostly of the carpentry sort. The table saw is the most significant item that produces dust, so I have a dust collector attached to it to keep the garage a little cleaner.

Well the dust collector has a pretty large collection bag, and whenever I have an oil spill (actually an oil drip spot from one of my Harley's) then I use the saw dust to dry up the spill and remove it.

I think it works as well as Kitty Litter, but I'm not planning on doing a comparison test either. It works for me and doesn't cost a thing, so it's all good.
