Carbon deposits form on pistons through time and engines produce a “Hot Soak”. 80% of all vehicles are started a minimum of 3 times a day; which is called “Hot Soak”. Carbon deposits need to be prevented by cleaning and removing these deposits. Intake valves get coated with crusty carbon deposits and the EGR adds exhaust carbon deposits as well. GDI engines spray into the combustion chamber and the thicker the carbon deposit build up on these values, the drivability gets worse and compression is lost. These deposits interfere with critical engine function and will damage other components if these deposits are dislodged. Turbochargers and/or catalytic converters will be damaged, causing replacement to be necessary. When one injector goes bad on a GDI engine, all injectors MUST be replaced at a costly expense.
Therefore, take care of your vehicle by maintaining it and service your vehicle every 6,000-10,000 miles or once a year. This product can also be used on non GDI vehicles for better gas mileage, pick up and pep of your vehicle.
