It’s really easy to use Just add water to the water line mark the fuel on top of it. Shake for about 10 seconds and then let stand for about 10 seconds. You will have your result. Nothing else needed for this test. **Q: How can a plastic bottle with just simple graduations cost so much? It cannot cost more than $0.35 a piece to make this thing.** A: The graduations are written on tape and then stuck on the bottle. I can see a price tag of maybe $3.95 not $14.95 like I paid. But it does work. **Q: does this test diesel fuel?** A: No, it tests for alcohol percent in gasoline. **Q: What if the gasoline your testing has sta-bil 22264 360 protection in it? will this still work?** A: I honestly can't say but I would think so.
