![]() If the fuel is not injected at this precise moment a misfire and power loss will occur. The reason is that diesel fuel is compression ignited at the top of the compression stroke when the cylinder pressure and heat are the highest, causing the fuel to ignite and start the power stroke. This sticking can cause a no start or hard starting issue. When it sticks in the bore, the Injector Driver Module has a hard time controlling exactly when fuel is injected. This valve must move from an open to closed position very fast to match the fuel timing. Stiction is where the poppet valve inside the Hydraulically Actuated Electronic Unit Injector (HEUI) sticks. I knew if a truck was coming in for a driveability or a cold starting concern it was likely due to injector stiction issues. There were only a few common issues with this engine and it almost always had to do with the engine oil or the glow plug system. Let’s start off with the 7.3L Powerstroke, Ford’s most reliable diesel. This was multiplied as the fuel injection system tolerances and injection process became much more precise in order to meet strict new emission standards. Each version of the Powerstroke through the years has had their fair share of problems. I was with Ford all the way through to the current 6.7L Scorpion engine. When I started working with Ford in 2005 I came at a prime time when the 7.3L Powerstroke was still coming in for warranty work and the problematic 6.0L was just getting started.

For a maintenance dose use only half the recommended initial amount. Hot Shot’s Secret Stiction Eliminator is made up of 100% additives so it can stay in the oil for the entire oil change.įor initial cleanup please refer to the initial treatment chart above. We recommend using with a fresh oil change, ideally with a full synthetic motor oil. Recommended for ALL diesel and gasoline engines. After Hot Shot Secret Stiction Eliminator was added to the engine, the analysis consistently showed only 1 injector needing replacement. Most of the time, the diagnostic analysis showed that 4 injectors needed replacement before treatment. The other 14% of the trucks showed improvement also. The owners noticed more power and a smoother running truck. 86% of the time, the analysis showed all the injectors were back online. The trucks were run only 100 miles and then the computer analysis was repeated. A treatment of Hot Shot’s Secret Stiction Eliminator was added to the engine oil. ![]() Computer analysis showed anywhere from 1 to 6 injectors needing replacement. Trucks having problems were hooked up to a diagnostic computer and tested. We have been testing Hot Shot’s Secret Stiction Eliminator since 2004. ![]() Friction modifiers and viscosity improvers make everything run smoother, with less friction and acid neutralizers help to prevent the built up soot in your engine oil. It also contains additives that make the motor oil work better. ![]() Stiction Eliminator is a combination of detergents and dispersants that clean up the carbon and oxidation inside the injector. If you have a diagnosis of a failed injector, then Hot Shot’s Secret Stiction Eliminator will fix this problem, even if the injector is at the point of not working. Recommended for ALL diesel and gasoline engines, even without symptoms like failing injectors, stiction is being made. When used in conjunction with Diesel Extreme (fuel additive), your engine will regain its original performance power. And you’ll save thousands of dollars by not replacing injectors that weren’t broken to begin with! In less than 4,000 miles you will see, hear and feel the difference as your injectors come back on line. Pour one treatment of our Original Stiction Eliminator into your oil BEFORE replacing your injectors. ![]() Scientifically formulated to eliminate the stiction build-up that causes most injectors to fail. It not only cleans injectors but other parts of the engine as well, including the turbocharger. Original Stiction Eliminator will stop excessive black smoke and bucking and chugging on cold starts. ![]()
