Hot Shot's Secret Diesel Fuel Additive 1 Gallon — Cleans Injectors, Raises Cetane & Disperses Water

Hot Shot’s Secret Diesel Extreme is a concentrated, 1-gallon diesel fuel treatment that cleans injectors and fuel system components, disperses water, and raises cetane for smoother combustion.

If your diesel engine needs a deep-cleaning fuel additive that also improves combustion quality and protects metal parts, this one-gallon formula is built for heavy-duty use. It combines detergents that dissolve varnish and injector deposits, moisture-dispersing chemistry to prevent corrosion, and cetane-boosting ingredients to help fuel ignite more efficiently. Use it as directed at filling time or on a routine schedule to maintain system cleanliness and component longevity.

How does Diesel Extreme clean the fuel system and injectors?

The formula targets both internal and external injector deposits as well as varnish and sludge in the upper cylinders, rings, and fuel lines. It uses detergents and solvents to break loose deposits and carry them safely to the fuel filter for removal.

• Removes Internal Diesel Injector Deposits (IDIDs) and External Diesel Injector Deposits (EDIDs).
• Dissolves varnish and carbon buildup on valves, pistons, and rings.
• Suspends contaminants so filters can capture them during normal operation.

Will this product improve fuel economy or engine performance?

By increasing cetane and restoring cleaner injectors, the additive helps fuel burn more completely and consistently. Improved combustion can translate to steadier power delivery and potential fuel-efficiency gains when used as part of regular maintenance.

• Raises cetane up to 7 points for crisper ignition.
• Reduces incomplete combustion caused by clogged injectors.
• Can decrease the frequency of diesel particulate filter (DPF) regenerations by improving burn quality.

How does Diesel Extreme protect against water and corrosion?

The product includes a non-alcohol water dispersant and military-grade rust inhibitors that stabilize fuel and protect metal surfaces. It helps prevent condensed moisture from corroding injectors, pumps, and tanks while maintaining lubrication properties.

• Disperses microscopic water droplets into the fuel for safe combustion.
• Contains rust and corrosion inhibitors rated for heavy-duty applications.
• Lubricates moving parts in the fuel system to reduce wear.

How do I use the one-gallon Diesel Extreme and dosing guidelines?

Dosage is simple and designed for practical intervals: pour the recommended amount at fill-up or schedule treatments every 6,000 miles. The concentrate mixes with diesel to treat large fuel volumes efficiently.

• Standard dosing: 8 oz per 20 gallons of diesel.
• One gallon treats multiple tanks depending on vehicle capacity — follow label instructions.
• Safe to add during refueling or before long hauls to maintain system cleanliness.

Who is this for? Hot Shot’s Secret Diesel Extreme, 1 gallon, is aimed at owners of diesel pickup trucks, agricultural machines, commercial fleets, and heavy equipment who want a professional-strength fuel treatment. It benefits users who put many miles on diesel engines, operate in variable climates where condensation is a concern, or run equipment that demands reliable injector performance. If you perform routine maintenance and prefer concentrated products to treat several tanks or multiple vehicles, this gallon-size additive is a practical, economical choice.
