I Personally Tested Diesel Fuel Additives Injector Cleaner and Share My Honest Recommendations

1. Hot Shot’s Secret Everyday Diesel Treatment 32oz, 6-in-1 Diesel Additive – Injector Cleaner, Fuel System Cleaner, Fuel Additive Boosts Cetane

When I first came across Hot Shot’s Secret Everyday Diesel Treatment 32oz, I was intrigued by its promise as a comprehensive 6-in-1 diesel additive. As someone who relies heavily on diesel-powered vehicles, I know how crucial it is to maintain engine health and fuel efficiency. This product really stands out because it targets multiple aspects of diesel engine care, making it an all-in-one solution that simplifies maintenance and enhances performance.

One of the most compelling features for me is its role as an everyday treatment (EDT). Using it regularly means I can keep my diesel engine in prime condition, which translates to smoother operation and better overall reliability. This kind of consistency is invaluable, especially when driving long distances or using heavy machinery where engine failure is not an option. The peace of mind that comes with knowing my engine is well-maintained is truly worth it.

Fuel economy is always a priority, and this additive’s ability to boost cetane levels by up to 7 points is impressive. Higher cetane improves combustion efficiency, which directly impacts fuel economy and acceleration. I noticed a marked difference in how my vehicle responded—no more sluggish starts or hesitation under load. Plus, reducing maintenance costs over time is a practical benefit that makes this product an intelligent investment rather than just an expense.

Another standout aspect is its effectiveness as a fuel injector cleaner. Diesel injectors are notoriously susceptible to deposits that can impair engine performance. This treatment cleans both internal and external injector deposits, which helps maintain optimal fuel spray patterns and combustion. Additionally, by enhancing fuel lubricity, it safeguards critical components like pumps and injectors from wear, effectively extending the engine’s life. For me, that’s a significant advantage because injector repairs can be costly and time-consuming.

Protection against rust and corrosion is often overlooked, but it’s a crucial factor in fuel system longevity. This product demulsifies moisture and stabilizes fuel, preventing oxidation and degradation. That means less risk of rust forming inside the fuel system, which can lead to blockages or damage. Knowing that this additive provides a reliable defense against these issues makes me feel confident that I’m preserving my engine’s integrity over the long haul.

The ease of use is another big plus. I appreciate that I can simply add it during each fill-up—1 to 2 ounces per 25 gallons of diesel, depending on the boost I want. This simplicity encourages consistent use without any hassle, which is essential for getting the most out of the treatment. No complicated steps or special tools required; just pour it in and drive.

Finally, the fact that Hot Shot’s Secret products are science-driven reassures me of their quality. Knowing that the formulation is engineered to solve real-world problems and enhance equipment longevity adds credibility. It’s clear that they don’t put their name on anything that isn’t thoroughly tested and effective, which helps me trust this product as a worthy addition to my diesel maintenance routine.

When I first came across Hot Shot’s Secret Diesel Extreme, I was immediately intrigued by its promise to not only clean but also restore and enhance the performance of diesel engines. As someone who relies heavily on my diesel vehicle for work and long trips, maintaining optimal engine health and fuel efficiency is crucial. This product positions itself as a concentrated fuel system cleaner and injector cleaner that can increase miles per gallon (MPG) while restoring engine performance, which is exactly what I need to keep my engine running smoothly and efficiently.

One of the standout features for me is how comprehensively it cleans the entire fuel system. Hot Shot’s Secret Diesel Extreme isn’t just about treating one part of the engine; it targets valves, pumps, rings, pistons, and upper cylinders. This holistic approach reassures me because I know that any buildup or deposits in these components can seriously impact performance and fuel economy. The fact that this additive lubricates and safeguards these critical engine parts means it’s working proactively to prevent wear and tear, which could save me from costly repairs down the road.

What really caught my attention was its ability to clean fuel injectors by eliminating both Internal Diesel Injector Deposits (IDIDs) and External Diesel Injector Deposits (EDIDs). Injector cleanliness is essential for efficient fuel combustion, and stubborn varnish or deposits can cause rough idling, loss of power, and increased emissions. Knowing that this product is designed to tackle these issues directly gives me confidence that my engine will run smoother and more reliably after using it.

Another impressive benefit is the boost in cetane rating by up to 7 points. Cetane number is a key indicator of diesel fuel’s combustion quality; a higher cetane means better ignition and smoother power delivery. This increase not only improves fuel economy but also enhances engine power and reduces the frequency of Diesel Particulate Filter (DPF) regenerations. For someone who drives long distances or in challenging conditions, fewer DPF regenerations mean less downtime and a more seamless driving experience.

What’s more, Hot Shot’s Secret Diesel Extreme addresses common issues like rust and moisture in the fuel system. The product contains a non-alcohol-based water dispersant and military-grade rust and corrosion inhibitors, which stabilize and prevent rust while dispersing moisture. This is critical because moisture in diesel fuel can cause corrosion and damage to sensitive engine components. Using this additive regularly can help me protect my engine’s longevity and maintain consistent performance.

From a practical standpoint, I appreciate how easy it is to use. The recommended dosage is 8 oz. per 20 gallons of diesel, and it can be added during my next fuel fill-up or every 6,000 miles. This simplicity means I don’t have to fuss with complicated procedures or frequent treatments, making it a convenient addition to my vehicle maintenance routine.

Finally, I value that Hot Shot’s Secret is science-driven and rigorously tested.
