**It is preferred to add Stiction Eliminator at a fresh oil change, however if added before please make sure overall oil level does not exceed oil fill level**

Stiction Eliminator was formulated to be kept in during the entire life of your oil.

Stiction Eliminator is safe and effective for use in all diesel and gasoline engines: semi-trucks, pick-up trucks, farm equipment, and autos. These include but are not limited to Ford Powerstroke, Dodge Cummins, GM Duramax, Saab, Volkswagen, Audi, Caterpillar, and Detroit.

Some products that are used to clean out stiction, the sludge and varnish created from burnt oil, contain harsh solvents and can cause wear to your engine. These products are meant to be added your engine oil and then removed shortly thereafter. This must be done so further harm doesn’t take place inside your engine. This also means these types of products cannot be as effective.

Hot Shot’s Secret Stiction Eliminator contains zero harmful solvents and was engineered to be left in your engine oil for thousands of miles. It contains a synthetic cleaner that safely and effectively removes stiction, while also lubricating. Stiction Eliminator can reduce wear up to 62% more than engine oil alone by removing stiction and using a nano lubricant. Stiction build up can lead to scarring of vital engine components which lead to failure. Removing stiction from the engine solves this problem. The nano lubricant inside this diesel oil additive for stiction also reduces the coefficient of friction, further reducing the normal wear and tear that takes place inside engines.

By removing power robbing stiction and utilizing a nano lubricant, Stiction Eliminator will also improve the performance of your vehicle by increasing fuel economy, improving power and compression, freeing stuck HEUI injectors and reducing blow-by.

Stiction Eliminator is guaranteed to improve your vehicles performance or your money back.

The Science

The Hot Shot’s Secret brand was built on our flagship product, Stiction Eliminator. We were commissioned by International Truck and Engine to formulate a product that eliminated the performance and warranty issues caused by stiction in the Navistar and Ford Powerstroke Hydraulic Electric Unit Injectors (HEUI injectors). Over the past 20+ years, we have continued to test, improve and find additional uses and benefits from the Original Stiction Eliminator.

Stiction is our term for the sticky friction caused by byproducts of burnt oil. High pressure builds extreme heat in tight tolerance applications, such as inside HEUI injectors. This extreme heat causes the oil to burn, oxidize and create layers of sludge and deposits. We found that many of the issues that Navistar and others were experiencing were caused by stiction in the oil cavities and on the spool valve in HEUI injectors.

In the case of HEUI injectors, computer diagnostics showing that HEUI injectors were failing were restored 9 out of 10 times after using Stiction Eliminator. Removing the stiction from HEUI injectors eliminates the hard starting when cold, bucking, chugging, missing and black smoke. Stiction Eliminator restores HEUI injectors back to factory specifications and rejuvenates your engine to optimal performance by restoring the oil flow through the injectors, which corrects injector timing, fuel flow and the spray pattern of your injectors.

Stiction Eliminator cleans the gum, varnish and stiction while also lubricating everything the oil touches inside your engine. Through extensive testing, we found that the chemistry of Stiction Eliminator, which restores HEUI injectors, also hold true for many other engine components. Stiction can form on many of the oil-wetted components inside your engine, like turbocharger bearings for example, which can reach temperatures upwards of 400°F. Turbocharger bearings operate with tight tolerance and extreme heat as mentioned above and are a known spot for stiction. Stiction Eliminator cleans the stiction from turbo bearings, which reduces spool time and helps you build maximum boost sooner in the RPM range.

Oil passages are kept clean, restoring the oil flow through your engine. Pistons, rings and oil pumps are also cleaned and lubricated. Dynamic compression is restored by increased ring sealing, providing improved combustion efficiency which translates to better fuel economy, power and a better running engine. Stiction Eliminator has been tested and proven on thousands of gasoline and diesel engines, from small lawn mower engines to large diesels.

Stiction Eliminator is composed of a safe but effective synthetic cleaner that dissolves the stiction found on oil-wetted components; resulting in a rating of 92% clean in the ASTM D4828 scrub test, and 98% clean when used in conjunction with Hot Shot’s Secret Blue Diamond Oil. A Group V synthetic ester assists in bringing deposits and additives back into solution, reducing friction and lubricating your oil system. Patented carbon nano particles are blended into Stiction Eliminator, filling in microscopic irregularities on the machined surface to provide a smoother surface for the lubricating film to form, which reduces friction and wear. Adding Stiction Eliminator to your engine oil results in a 62% decrease in wear over oil alone as verified by ASTM G-133 Third Party testing. The result is a cleaner, better running and longer lasting engine.

Even if you aren’t experiencing the symptoms associated with stiction, it is still being created. Stiction Eliminator should be used a preventative measure to avoid stiction problems in the future. Stiction Eliminator was formulated to be left in for the entire duration of your oil’s lifetime. It is not a flush that contains harsh solvents which can potentially harm your engine.

Stiction Eliminator’s unique chemistry allows it to clean and lubricate oil-wetted components safely, which cannot be accomplished with many of the competitor products available. Whether used to solve an existing problem or as a preventative measure, Stiction Eliminator is guaranteed to clean and protect your engine.

Common Questions About Hot Shot’s Stiction Eliminator

Whether you are buying a stiction reducer for your own vehicle or for your business, you need all the facts to make a confident purchasing decision. Find answers to common questions about Hot Shot’s Secret Stiction Eliminator below.

How does Stiction Eliminator work?

Hot Shot’s Secret Stiction Eliminator engine oil additive makes starting easier, improves engine performance and decreases wear by removing stiction from components. The synthetic cleaner in Stiction Eliminator dissolves the sticky residue that burnt oil leaves on oil-wetted parts, reducing friction and leaving HEUI injectors, rings, oil pumps and other parts of the engine clean. At the same time, the proprietary carbon nano lubricant included in our stiction reducer coats machined surfaces, filling in irregularities to further reduce friction and wear on engine components.

Stiction Eliminator’s unique formula gets rid of stiction with minimal effort on your part. Just add it to your engine oil and see results quickly. To learn more about how Hot Shot’s Secret Stiction Eliminator improves fuel economy, review the official test results.

Will Stiction Eliminator work for my engine?

We have engineered Stiction Eliminator for use in both gasoline and diesel engines, as well as a wide range of vehicle and machine types — from agriculture and construction equipment to RVs, motorcycles, semitrucks and marine engines. Although Stiction Eliminator was originally created to solve problems with stiction in Hydraulic Electric Unit Injectors (HEUI), the product effectively cleans and lubricates components in non-HEUI engines, as well.

When should I add Stiction Eliminator?

The best time to add Hot Shot’s Secret Stiction Eliminator is during a fresh oil change. However, you can opt to add Stiction Eliminator at any time without issue. When adding Stiction Eliminator for the first time, the recommended dose is 4 ounces per quart of oil. After the initial dose, 2 ounces per quart of oil is usually enough to keep components clean.

Does Stiction Eliminator Replace part of my oil?

Hot Shot’s Secret Stiction Eliminator replaces an equal amount of oil. If used during a fresh oil change just exchange an equal amount of oil for Stiction Eliminator. When adding Stiction Eliminator in the middle of an oil change cycle, drain some oil from the engine. Be sure to check that the overall oil fill level does not exceed the OEM recommendation.

How long does it take for Stiction Eliminator to work?

Stiction Eliminator works relatively quickly. However, you should keep in mind that the amount of time it takes the engine oil additive to remove stiction and provide lubrication will depend on how much buildup already exists inside the engine. Some customers experience a difference in as little as 50 miles, while other customers see results after the full oil change cycle. Spirited driving and hauling heavy loads can help Stiction Eliminator work more quickly.

Why should I choose Stiction Eliminator over other injection cleaners?

Some injection cleaners remove stiction using harsh solvents which can cause damage to your engine if they remain in circulation too long. This formulation means most other stiction reducers will require you to remove them shortly after you add them to your engine oil, which limits their long-term effectiveness and makes them inconvenient to use.

Hot Shot’s Secret Stiction Eliminator is different — our formula contains no harsh solvents, so you can leave it in until your next scheduled oil change. Because Stiction Eliminator can safely remain inside the engine, it can also lubricate components and reduce wear.
