Depending on the quality, type and source of the gasoline, as well as storage conditions, doubling the dosage rate of STA-BIL® brand could prolong this storage time to up to 2 years. However, any gasoline stored for more than 12 months will tend to lose volatility (ignitability), which could lead to hard starting or no start conditions after this long storage period. NO additive, STA-BIL® brand included, will prevent volatility loss in fuel. To reduce fuel volatility loss during storage, we recommend filling your tank at least 95% full with fresh fuel and STA-BIL® brand, and store in cool conditions away from direct sunlight if possible.

No, over-dosage is perfectly OK. However, we do not recommend adding more than 4 times the recommended amount. If more than 4 times has been added we recommend diluting the fuel.
STA-BIL will eventually evaporate, although this can take some time. However, a stain may occur depending on the type of surface it may have been spilled on. To help clean it up, we recommend trying alcohol on wood, vinyl, or other materials, then regular soap and water. For asphalt or concrete, you may use mineral spirits and then rinse with a high-pressure water.
