Hot Shot's Secret Diesel Fuel Additive 64 oz — Concentrated Cleaner & Fuel Stabilizer for Injectors

Hot Shot's Secret Diesel Extreme Fuel Additive (64 oz) is a concentrated diesel treatment formulated to clean fuel tanks, lines, and injectors while stabilizing fuel, removing free water, and improving lubrication.

This 64-ounce bottle delivers a professional-strength dose for diesel tanks of various sizes. Designed for diesel vehicles, trucks, equipment, and seasonal storage, the formula targets deposits and contaminants that reduce performance and long-term reliability. Use it as part of routine maintenance or before seasonal storage to maintain cleaner components and smoother operation.

How does this additive help diesel systems perform better?

It combines detergents and conditioning agents to break down deposits and protect moving parts in the fuel system. The cleaner action helps restore injector spray patterns and maintain efficient combustion without altering the engine or fuel specifications.

• Removes varnish and carbon deposits from injectors and lines.
• Lubricates fuel pump and injector components to reduce wear.
• Helps improve ignition quality by stabilizing cetane levels.

Can this product remove water and prevent problems from free water?

Yes — the formulation includes water-dispersing agents that gather free water and allow it to pass safely through the system to be removed at the filter or drained. This reduces microbial risk and corrosion potential caused by separated water.

• Breaks free water into manageable droplets for filtration.
• Helps limit microbial growth that thrives in water-contaminated fuel.
• Works alongside regular fuel filters and water separators.

How often should I use Diesel Extreme for best results?

Frequency depends on vehicle use and fuel quality: treat at every fill-up when using suspect fuel, or apply as a scheduled maintenance treatment every few tanks for routine protection. For seasonal storage or long idle periods, add before storing to keep fuel stabilized.

• Use at tank fill-up if fuel origin or quality is uncertain.
• Apply before winter storage to stabilize fuel and protect components.
• Follow dosing instructions on the bottle for tank capacity and concentration.

What specific maintenance benefits does this 64 oz bottle provide?

A single 64 oz container treats multiple tanks depending on dose, making it practical for fleets or frequent users. It targets common diesel fuel problems so daily operation stays smoother and fuel system parts receive added protection.

• Clean out tank, lines, and injectors to restore performance.
• Stabilize fuel and boost cetane to promote reliable ignition.
• Lubricate fuel pump and injectors to reduce component wear.

Who is this for? Hot Shot's Secret Diesel Extreme Fuel Additive, 64 oz is aimed at diesel vehicle owners, fleet managers, commercial operators, and equipment users who want proactive fuel-system maintenance.
