## Questions & Answers

A: You can use it many times. 
It’s really easy to use

**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: 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?**
