Hot Shot's Secret Everyday Diesel Treatment 4oz (24 Pack) - 6-in-1

In this review of Hot Shot's Secret Everyday Diesel Treatment, the verdict is straightforward: this 6-in-1 diesel additive is aimed at diesel owners who want a simple, regular maintenance step to keep engines running smoothly and to protect fuel-system components. The reviewer found it best for drivers who top up at the pump and want measurable gains in drivability and fuel economy without complex installation. The single biggest reason to buy is its combination of injector cleaning, cetane boost and corrosion protection in a bottle intended for every fill-up.

Key Features

• Everyday treatment: Designed for regular use at each fill-up to maintain engine health and promote consistent performance over time.
• Cetane boost: Raises cetane levels by up to 7 points, which can improve combustion efficiency and help with acceleration and fuel economy.
• Injector cleaner: Cleans internal and external injector deposits to restore spray patterns and smoother idle and throttle response.
• Rust and corrosion prevention: Demulsifies moisture and stabilizes fuel to reduce oxidation, helping protect pumps, injectors and other fuel-system parts.
• Fuel lubricity: Adds lubricity to diesel to help safeguard the fuel pump and injectors and extend component life.
• Easy dosing: Simple measuring: use 1 oz. or 2 oz. per 25 gallons depending on the desired cetane and lubricity boost, poured directly into the tank.

Who It's For

This product is best for truck owners, fleet operators and everyday drivers who prefer a maintenance routine tied to refueling and want a multi-purpose additive that targets injectors, cetane and corrosion in one step. It suits vehicles that see regular highway or towing duty where injector cleanliness and fuel stability matter.

Those who require specialty fuels, specific OEM-mandated additives, or laboratory-grade diesel treatments for extreme conditions should look elsewhere. Also, if packaging reliability is critical, users should be aware some customers have reported occasional leakage from the cap and may choose a different container style.

Pros & Cons

Pros

• Improves fuel economy and drivability by boosting cetane and cleaning injectors, with customers noting gains like 2 mpg and smoother acceleration.
• Combines multiple benefits-injector cleaner, lubricity, corrosion prevention-so one product handles routine fuel system care.
• Easy dosing at the pump makes it convenient for regular use and predictable treatment per gallons of fuel.
• Engineered formulation intended to extend equipment life and reduce maintenance frequency.

Cons

• Some users report leakage from the cap, which can be messy and wasteful if not stored carefully.
• Opinions on odor are mixed; a few users find the smell noticeable, so those sensitive to strong scents may want to test a single bottle first.
