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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Additive for fuel *by N***P on March 1, 2026* This stuff works.
