## Questions & Answers

**Q: Should I really use STA-BIL 360 Marine before every fill-up? Is it truly necessary?**
A: To be blunt, yes, especially if you want to protect your investment. Boats live in a high-moisture environment. STA-BIL 360 Marine is engineered to protect your tank from corrosion and optimize the fuel in the process.

**Q: If the color of the liquid in the bottle is no longer blue, is it still safe to use?**
A: Yes. It is possible for the dye in the formula to fade, but it is still perfectly functional.

**Q: What happens if I add too much fuel additive to my tank? Will it harm the engine?**
A: No. Overpouring will not cause significant damage to your fuel tank. However, it’s best practice to avoid making this a habit. Miscalculating by an ounce here or there, so long as it is not over four total ounces, is acceptable.
