What is diesel injector stiction?
Stiction is the sticky, gummy residue of burnt oil on moving engine parts that causes dragging friction. Stiction can occur on your diesel’s HEUI injectors, o-rings, springs, piston and the turbocharger. The most obvious symptom of stiction is a diagnosis of a failed injector.
What are the symptoms of stiction?
Stiction: Cause and Effect It leads to inconsistent fuel quantities leaving the injector nozzle, and poor fuel atomization occurring in-cylinder. Common symptoms are hard starting, rough idling, and oftentimes a truck that’s smoking while it warms up in the driveway.
What causes injector stiction?
“Stiction occurs over time when the engine oil breaks down and leaves a gummy residue on the internal parts of your injectors which causes a dragging effect,” said John Filion of Rev-X, a manufacturer of high performance oil and fuel additives.
How do you stop a stiction injector?
Stiction can be combated using a specially formulated oil additive and it’s onset time reduced by using a quality synthetic engine oil changed at OE recommended intervals.
How long does it take for stiction eliminator to work?
Q: How long does it take for Stiction Eliminator to work? A: While using Stiction Eliminator customers have reported 50 miles and others it takes the entire oil change cycle. It will eventually clean up the deposits and restore your performance to normal.
Whats the difference between stiction and friction?
It is the sum of the static friction forces in all the moving components of the system. In other words, stiction is the total static friction that must be overcome in order to cause motion in a body at rest. Stiction often results in a system overshooting its commanded position.

Does hot shot stiction Eliminator really work?
We have been testing Hot Shot’s Secret Stiction Eliminator since 2004 and have found it to be 90% effective in fixing HEUI injectors. Trucks having problems were hooked up to a diagnostic computer and tested. Computer analysis showed anywhere from 1 to 6 injectors needing replacement.
Does Hot Shot diesel additive work?
The good news is, this hot shots secret whatever, it does work. I can attest to good throttle response, quieter injectors and less valve rattle in both diesels I own.. However, there’s no noticeable difference between hot shots and diesel kleen in the gray bottle that I can vouch for, even on my scan tool.
What happens when stiction is present in a control valve?
In presence of stiction, the movement is jumpy. In a control loop, stiction is a big problem, since the controller will push to move the valve until the process variable reaches the setpoint. If stiction is present, the valve Page 7 will move too much and the process variable will overshoot.
Can you mix FR3 with a stiction eliminator?
Following Stiction Eliminator, Hot Shot’s Secret recommends adding their FR3 Friction Reducer on the next oil change at a ratio of 1.5 ounces to every 1 quart of oil for long-term engine performance, restored power and improved MPG.
Is synthetic diesel oil better?
Is synthetic oil better for my engine than conventional oil? Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can’t compete with the overall engine performance and protection provided by synthetics.
How often should you change the oil in a 6.0 Powerstroke?
every 5,000 miles
6.0L Powerstroke Service Schedule When it comes to your 6.0, you’re going to need to perform maintenance more frequently than what your owner’s manual calls for. The oil and oil filter need to be changed every 5,000 miles like clockwork.
Does hotshots stiction eliminator work?
How long does it take for Stiction Eliminator to work?
What causes stiction in fuel injectors?
The design of these injectors incorporates oil, which is passed through the injector at a very high PSI to pressurize the fuel. This high pressure and heat pulls in excess oil, which breaks down and creates a gummy residue on the injectors’ internal parts. This causes the static and friction — stiction.
What is a stiction eliminator for diesel injectors?
Hot Shot’s Stiction Eliminator for gas and diesel engines safely removes and prevents the gummy, sticky residue that builds up inside diesel HEUI injectors over time. It cleans and lubricates the entire oil side of the engine: injectors, turbo, rings, oil pump, everything the oil touches.
What is stiction and how does it affect your diesel engine?
When any hydrocarbon is over-heated, it leaves a sticky residue that can cause stiction, which can negatively impact the fuel system and transmission. While not intentional in design, burnt hydrocarbons creating stiction are a natural byproduct of the diesel engine. Whether using synthetic oil or high quality fuel, stiction is inevitable.
How much psi does a diesel injector put out?
Older injectors would put out 1,200 PSI at the injector tip but the new diesel engines put out 30,000 PSI. To achieve this increase in pressure, the manufacturers had to tighten the tolerance inside the injector, which increased the friction and temperature.
