Product discrepancy

It's a good product. However, product description says 1 bottle treats up to 21 gallons of gas, while what I have received (and what's available in stores) 1 bottle treats up to 15 gal of gas. Kinda mismatch...

It is the perfect additive to your gasoline to help your vehicle perform at its best. There is nothing a consumer can do about the qualify of gasoline at the pump. STP is that blessed hope. Please continue to keep this product in stock at affordable prices.
