Throttle Muscle GDI One Step Synthetic Fuel System Cleaner has more cleaning agents than other leading GDI cleaners and also contains a 108 Octane Booster along with a synthetic fuel system lubricant. While no pour in fuel system cleaner is going to clean 100% of the GDI system, our unique formulation helps keep the GDI system clean and helps maintain performance. Regular use will help prevent costly build-up in the GDI system.
