Starting at the fuel injectors or carburetor jets, the cleaner dissolves and removes varnish, gum, and carbon deposits that accumulate over time and restrict fuel flow. It then continues through the intake valves, removing carbon buildup that is particularly problematic in direct injection engines where fuel doesn't wash the valves. Finally, it cleans combustion chamber deposits that cause pre-ignition, knock, and reduced compression. This comprehensive cleaning restores the fuel system to near-new condition.\u003c\/p\u003e\n\u003ch4\u003eRestores Fuel Economy:\u003c\/h4\u003e\n\u003cp\u003eFuel injector deposits are one of the most common causes of reduced fuel economy. Even a small amount of deposit buildup can alter the injector's spray pattern, reducing atomization efficiency and causing incomplete combustion. Max-Clean dissolves these deposits, restoring the injector's original spray pattern and improving fuel atomization. The result is more complete combustion, better fuel economy, and improved throttle response. Most users report noticeable improvements in fuel economy after a single treatment.\u003c\/p\u003e\n\u003ch4\u003eIntake Valve Cleaning - Critical for Direct Injection Engines:\u003c\/h4\u003e\n\u003cp\u003eDirect injection (DI) engines are particularly susceptible to intake valve carbon buildup because fuel is injected directly into the cylinder rather than the intake port. In port-injected engines, fuel washes the intake valves with every injection cycle, keeping them clean. In DI engines, oil vapors from the PCV system coat the intake valves and bake on as carbon deposits. These deposits restrict airflow and cause rough idle, hesitation, and power loss. Max-Clean's intake valve cleaning capability helps address this issue, making it especially valuable for modern DI engines found in many performance vehicles.\u003c\/p\u003e\n\u003ch4\u003eFuel Stabilizer for Storage:\u003c\/h4\u003e\n\u003cp\u003eMax-Clean also functions as a fuel stabilizer, making it ideal for vehicles that will be stored for extended periods. Modern gasoline, especially ethanol-blended fuel, degrades relatively quickly - within 30-60 days it can begin to form varnish and gum deposits that clog fuel system components. Max-Clean stabilizes the fuel, preventing degradation for up to 12 months. This makes it an essential treatment before storing seasonal vehicles, track cars, or any vehicle that won't be driven regularly.\u003c\/p\u003e\n\u003ch4\u003eCompatible with All Gasoline Engines:\u003c\/h4\u003e\n\u003cp\u003eMax-Clean is compatible with all gasoline engines including those running ethanol blends (E10, E15, E85). It is safe for use with fuel injectors, carburetors, oxygen sensors, and catalytic converters. The formula is compatible with all fuel system materials including rubber seals and plastic components. It can be used in naturally aspirated and turbocharged engines, making it suitable for the full range of performance vehicles.\u003c\/p\u003e\n\u003ch4\u003eWhy Royal Purple?\u003c\/h4\u003e\n\u003cp\u003eRoyal Purple is a world-renowned manufacturer of high-performance lubricants and additives, trusted by professional race teams and enthusiasts worldwide.
