Hot Shot's Secret Diesel Extreme Fuel Additive — 1 Gallon Concentrate, Cleans Injectors & Boosts Cetane

Hot Shot's Secret Diesel Extreme Fuel Additive (1 gallon) is a concentrated diesel treatment that cleans injectors and fuel system components, boosts cetane, disperses water, and protects against rust and corrosion.

This one-gallon formula is formulated for diesel engines that need a deep clean and improved combustion performance. It targets internal and external injector deposits, varnish, and other contaminants while lubricating pumps and upper cylinder parts. Designed for periodic maintenance or intensive remediation, the treatment works when added to the fuel tank at recommended dosing intervals.

How does Diesel Extreme clean my fuel system?

The formula contains detergents and solvency agents engineered to dissolve carbon, varnish, and gum that build up on injectors, valves, rings, pistons, and upper cylinders. Regular use restores proper spray patterns and fuel flow to help engines run more smoothly.

• Targets Internal Diesel Injector Deposits (IDIDs) and External Diesel Injector Deposits (EDIDs)
• Removes varnish and sticky deposits from injectors and upper cylinders
• Leaves lubricating film on pumps and moving parts to reduce wear

Will it improve engine combustion and fuel economy?

Diesel Extreme includes cetane-boosting components that can raise cetane numbers by several points, promoting faster and more complete ignition. Improved combustion can translate to smoother throttle response and potential gains in fuel efficiency under many operating conditions.

• Cetane increase that supports better ignition timing
• Reduces incomplete combustion that causes smoke and rough idling
• May lower frequency of diesel particulate filter regenerations in some setups

How does it handle water and corrosion in diesel fuel?

The product is a non-alcohol water dispersant fortified with corrosion inhibitors adopted from military‑grade chemistry. It helps emulsify small amounts of water in fuel so they pass through the system without pooling, while the inhibitors form a protective barrier to slow rust and corrosion.

• Non-alcohol dispersant to safely manage trace water in fuel
• Military‑grade rust and corrosion inhibitors protect metal components
• Stabilizes stored fuel and reduces risk of rust-related failures

How do I use this gallon-sized treatment and what dosing is recommended?

Application is straightforward: add the specified dose to the fuel tank during a fill-up or at routine service intervals. The concentrate covers a lot of fuel, so a single gallon can treat many tanks depending on your dosing schedule.

• Use 8 oz per 20 gallons of diesel, or follow vehicle/service guidelines
• Pour into the tank during refueling or every ~6,000 miles for maintenance
• Ideal for fleet, agricultural, heavy equipment, and individual owners

Who is this for? Hot Shot's Secret Diesel Extreme is suited for owners of diesel cars, trucks, RVs, agricultural machines, construction equipment, and fleet vehicles who want to remove injector deposits, improve combustion, and protect fuel system components. It's especially helpful when engines exhibit rough idle, decreased power, increased smoke, or when fuels sit in storage. Use as part of routine maintenance or to tackle more significant deposit-related performance issues. Follow manufacturer guidance for compatibility with emission controls and specific engine types.
