Hot Shot's Secret Diesel Extreme Fuel Additive — 64 oz Concentrated Cleaner & Water Remover

Hot Shot's Secret Diesel Extreme is a 64 oz concentrated diesel fuel additive formulated to clean fuel systems, remove free water, stabilize fuel, boost cetane, and lubricate pumps and injectors.

This 64-ounce formula is designed for diesel engines that need a comprehensive treatment for fuel-related issues. It combines detergents, water-removal agents, stabilizers, and lubricants so you can treat tanks, lines, and injectors in one go. Use it in cars, trucks, RVs, or off-road equipment to address deposit build-up, micro-water contamination, and low fuel lubricity without altering basic fueling habits.

How does this additive clean tanks, lines, and injectors?

The concentrated detergents and solvents in the formula loosen and dissolve gum, varnish, and soot that accumulate in the tank, lines, and fuel injectors. Regular treatments help restore spray pattern and injector flow, which supports steadier combustion and easier cold starts.

• Breaks down deposits on injectors and intake passages
• Clears residue from fuel lines and filters to improve flow
• Helps maintain consistent injector spray patterns

Can it remove water and why does that matter?

Yes — this product contains water-dispersing agents that separate free water from diesel so it can pass safely through filters instead of reaching injectors. Removing micro and free water reduces corrosion, microbial growth, and injector wear without requiring tank draining in many cases.

• Separates and disperses free water for safer filtration
• Helps inhibit microbial contamination growth fed by water
• Reduces corrosion risk to metal fuel system components

What performance benefits should I expect after treating my fuel?

Treating diesel with this additive can stabilize fuel quality, raise effective cetane number, and add lubricity to protect pumps and injectors. These improvements support smoother running, fewer rough-idle events, and potentially easier starting in cold conditions, depending on engine and fuel quality.

• Stabilizes fuel chemistry to resist oxidation and degradation
• Boosts cetane to improve ignition consistency
• Adds lubricity to protect high-pressure pumps and injectors

How do I use the 64 oz bottle and how often should I treat my tank?

The bottle contains a concentrated dose for treating multiple tanks; follow mixing ratios on the label for your tank size. For routine maintenance, treat each tank fill or every few thousand miles depending on use; for contaminated systems, perform an initial aggressive treatment then maintain regularly.

• Pour directly into the fuel tank prior to refueling when possible
• Follow on-label dosage for tank gallons to ensure correct concentration
• Use an initial cleaning dose for heavily fouled systems, then maintain

Who this is for: Diesel Extreme is intended for diesel vehicle owners, fleet managers, and equipment operators who want an all-in-one fuel treatment to address deposits, water contamination, and fuel stability. It's useful for road trucks, pickups, agricultural machinery, marine diesels, and seasonal equipment stored between uses. If you need to reduce injector wear, control fuel-related performance issues, or maintain fuel during storage, this product offers a concentrated, easy-to-use solution.
