Cetane Power Booster Case 12 x 16 Oz.

The Cetane Power Booster Case, 12 x 16 oz bottles by Lucas Oil, is a diesel fuel system additive designed to restore combustion efficiency and injection timing precision in diesel engines that have accumulated carbon deposits or fuel system varnish. As a mechanic working on commercial and personal diesel vehicles, you know that modern diesel engines demand precise cetane ratings and clean injectors for optimal performance—especially in older trucks or equipment that runs lower-grade fuel. This case format provides a full season's supply for fleet maintenance or long-term engine care, making it ideal for contractors, owner-operators, and serious diesel enthusiasts who refuse to compromise on fuel quality.

Cetane improvers work by accelerating the ignition delay period in the combustion chamber, allowing fuel to burn more completely and consistently across engine load cycles. Lucas Oil's formulation elevates cetane ratings by up to 7–8 points per dose, which translates to faster cold starts, smoother idle quality, and reduced white smoke during warm-up—telltale signs of poor combustion. Each 16 oz bottle treats approximately 250–500 gallons depending on baseline fuel condition; the additive package also contains detergents that dissolve injector varnish buildup and prevent new deposits from forming on valve seats and combustion chamber walls. This dual-action approach restores volumetric efficiency without requiring fuel system flushing or injector removal in most cases.

Any diesel engine operating on pump fuel will benefit from seasonal cetane treatment, particularly Cummins, Duramax, Powerstroke, and inline-six platforms that log high mileage or run in cold climates where fuel gels and combustion lags. Construction equipment, agricultural machinery, and marine diesel engines are equally good candidates. Simply add one bottle to your fuel tank before filling—no special equipment or downtime required. Mechanics routinely recommend this Lucas Oil case to customers reporting rough idle, hard starting, or decreased fuel economy, with most seeing measurable improvement within one or two fuel cycles.
