## Questions & Answers

**Q: How many gallons does it treat?**
A: The front of the container states "Treats up to 21 gallons" -- my husband uses this product in our 1965 Mustang, which has a tank size of  16 gallons.  Depending on how often he drives the car and fills the gas tank, he uses 1 bottle with each fill up.    I hope this answers some of your question.

**Q: does this work on a 2 stroke?**
A: Does your 2 stroke recommend a higher octane - 89+ and you can't get the fuel? if so, use it

**Q: Is this safe for use with catalytic converters?**
A: I am using it in a 66 Mustang and a 73 Z28 neither have converters, so not sure

**Q: Will this stuff boost 93 octane to 95?**
A: Yes, I think it is a gain of just under 2.5 octane numbers when added to 12 or 14 gallons.
