## Questions & Answers

**Q: Would this super concentrated cleaner damage my 02 sensors? Literature does not say about sensors.**
A: It's safe for O2 Sensors. Every gasoline vehicle has them at this point (unless you drive a 57 Chevy or something). All Brand Name products have been tested for O2 Sensors and STP has a good reputation. I have O2's in my car and use this all the time with no problems.

**Q: how many gallons will one bottle treat**
A: 21 gallons

**Q: How often should i use it?**
A: After every oil change

**Q: can I use it more ofen?like every time filling gas?**
A: I used every time I fill up my tank. Just don't use more than recommend since if you use too much it can foul spark plugs. I once had a engine not start cuz the fuel was fouling the spark plugs from a fuel additive.
