The two 1\/2 gallon jugs treat a combined 500 gallons of diesel and are formulated in the U. S. A. to restore horsepower, improve mileage, and reduce smoke. The single biggest reason to buy is the combination of a cetane improver and lubricity restoration that customers report produces smoother idling, easier starting, and a measurable reduction in fuel consumption in everyday use.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in the U.
