The Lubrication Specialties Hot Shot's Secret Stiction Eliminatoroil additive is a formula made from a combination of detergents and dispersants, which can be added to new or used motor oil. Hot Shot’s Secret Stiction Eliminator then works to remove 100 percent of the build-up caused by the coking and varnishing left behind from overheating the engine’s oil, the company says. When stiction exists inside the engine, performance and efficiency decreases and overall wear is increased. Stiction Eliminator can remain in the engine oil for the entire oil change and adds a superior level of lubricity back into the oil.
