One fluid ounce treats 32 gallons of diesel. A 16 oz bottle treats 512 gallons, and overdosing is not harmful.

How long does it stabilize fuel?

It prevents oxidation and stabilizes diesel chemistry for at least two years, which suits boats and equipment stored for the off-season.

Will it clean my injectors?

It is made to eliminate carbon build-up on injectors and exhaust components and to reduce soot and particulate smoke.
