Product Overview

Hot Shot’s Secret HSS64Z Original Stiction Eliminator is an engine oil additive manufactured by Lubrication Specialties Inc., targeting both gas and diesel engines—particularly those prone to internal oil-wetted component buildup. The primary function of this product is to remove “stiction,” a portmanteau of sticky friction, referring to the accumulation of burnt oil, sludge, and carbon deposits inside engine parts such as injectors, turbochargers, piston rings, and oil pumps. The manufacturer claims its proprietary blend of synthetic cleaner and carbon nano lubricant not only cleans these internal components but also lubricates and protects them, improving engine performance, idle smoothness, and longevity. The HSS64Z is especially recommended for high-mileage vehicles, diesel trucks (notably those with HEUI injectors), and older engines suffering from idle issues, noise, or sluggish acceleration. It can also be used as a preventative maintenance product in newer vehicles. Hot Shot’s Secret positions this additive in the mid-range price bracket, with a reputation for offering a robust money-back guarantee if the user is dissatisfied with its performance.

Detailed Assessment

Functionality & Benefits

Rating: 5/5 – Hot Shot’s Secret Stiction Eliminator delivers on its core promise of cleaning and lubricating oil-wetted components. Verified users report notable improvements in idle smoothness, reduced engine noise, improved acceleration, and a generally cleaner running engine after use. The product’s ability to restore HEUI injectors and clean turbochargers and piston rings positions it as a highly functional solution for common issues in diesel and gasoline engines, with especially strong results in older or high-mileage vehicles.

Technology & Innovation

Rating: 4.5/5 – The proprietary blend of a synthetic cleaner and carbon nano lubricant is the hallmark of the Stiction Eliminator, setting it apart from generic oil system flushes. Unlike many competitors that rely on harsh solvents requiring short-term application, this additive is formulated to remain in the engine for the full oil change interval, promoting ongoing cleaning and lubrication without risk of harm. While not unique to Hot Shot’s Secret in concept, the formulation’s safety and efficacy present a clear technological advantage.

Ease of Use

Rating: 5/5 – Application is straightforward: add the recommended amount to the engine during an oil change, then drive as usual. There is no special procedure, flush, or premature oil change required, and the product can be left in the engine until the next scheduled oil change. Users have consistently noted that the process is as simple as adding oil, with no additional tools or steps needed.

Market Popularity

Rating: 4/5 – Stiction Eliminator has gained substantial traction among diesel truck owners, particularly within enthusiast communities that advocate preventative maintenance for HEUI injector systems. While it remains especially popular in the diesel segment, it is increasingly being adopted by gasoline vehicle owners as awareness grows. It ranks as one of the best-known products in its category, though some skepticism persists among professional mechanics and traditionalists.

Customer Satisfaction

Rating: 4.5/5 – The overwhelming majority of verified customer reviews are positive, citing significant reductions in engine noise, smoother idle, and restored performance in engines with moderate to severe deposit buildup. Dissatisfaction usually centers on unclear or unrealistic expectations regarding instant results, or on use in engines unlikely to be affected by stiction in the first place. The manufacturer’s money-back guarantee also adds customer confidence.

Competitive Comparison

Rating: 4/5 – Compared to competitors like Archoil AR9100 and Rev-X Oil Additive, Hot Shot’s Secret Stiction Eliminator is similarly priced and delivers comparable results for cleaning and lubricating HEUI injectors. Archoil is sometimes noted for slightly quicker results in cold idle, while Rev-X is preferred by some for its extreme high-pressure lubrication. However, Stiction Eliminator stands out for its ability to be left in the engine throughout the oil interval, reducing maintenance hassle and maximizing convenience. Some competitors still rely on more aggressive solvents, which pose a higher risk to sensitive engine parts.

Performance Results

Rating: 4.5/5 – Measurable performance gains include quieter idle, increased throttle response, improved acceleration, and in several cases, the restoration of injector function especially in 6.0L and 7.3L Ford Powerstroke diesel engines. While these benefits are most dramatic in engines with pre-existing stiction issues, preventative use has shown subtle gains in overall engine smoothness and longevity. Results are generally noticeable within the first 100-500 miles post-application.

Value for Money

Rating: 4/5 – Considering its mid-range price and the frequency with which it can be used (once per oil interval), Hot Shot’s Secret Stiction Eliminator provides solid value—particularly for owners of high-mileage engines, diesel trucks, and vehicles with known stiction-related symptoms. Its performance, safety for long-term use, and robust money-back guarantee position it as a worthwhile investment compared to both less effective, cheaper alternatives and higher-priced specialty additives.

Verdict

Hot Shot’s Secret HSS64Z Original Stiction Eliminator is a proven, technically robust solution for internal engine sludge and varnish buildup. Its strongest points are its efficacy in cleaning and lubricating oil-wetted engine components, ease of use, and ability to remain in the engine oil for the full service interval without risk. The proprietary formula, which avoids harsh solvents, makes it especially attractive for sensitive HEUI injector systems and high-mileage turbocharged diesel engines—such as Ford Powerstroke 6.0L and 7.3L trucks. It is also well-suited to gasoline engines in need of preventative maintenance. The main caveats are that results are naturally less dramatic in newer engines or those using high-quality synthetic oils without significant stiction, and that some skepticism persists among critics who question the overall necessity of oil additives.

For vehicle owners experiencing rough idle, sluggish acceleration, or injector-related trouble codes, this product delivers measurable benefits. It is equally valuable as a preventative tool in vehicles at risk for deposit buildup due to high mileage, severe duty cycles, or suboptimal maintenance histories. Overall, Hot Shot’s Secret Stiction Eliminator is Highly Recommended for diesel and gas engine owners looking to maintain peak performance and extend engine life, with an overall rating of 4.5/5.
