What You'll Learn
Royal Purple's Max-Clean Fuel System Cleaner
The oxidative stability of hydrocarbons in fuel impacts how quickly they chemically break down to form gums that stick to engine surfaces and bake into deposits. By delaying or preventing the onset of oxidation, Max-Clean reduces the formation of these gums, resulting in fewer deposits. This, in turn, reduces the clean-up burden of fuel detergents.
Max-Clean also helps stabilize fuel during low-use and storage periods, preventing the varnishing of fuel. It should be used every 10,000 miles or annually, whichever comes first. To use, pour the entire contents of the 20 oz. can into a nearly empty tank and then refuel. One can treat up to 20 gallons of fuel. For tank sizes outside of this range, use one ounce per gallon, and for two-cycle engines, use one ounce per gallon.
Customers have reported improved engine performance, with significant improvements in smoothness and acceleration, as well as increased fuel efficiency of up to 2 miles per gallon. It is recommended by Scotty Kilmer, a well-known car guru on YouTube.

Max-Clean's impact on engine performance
Royal Purple's Max-Clean is a state-of-the-art synthetic fuel system cleaner and fuel injector cleaner. It is designed to deeply penetrate and clean injectors, carburetors, intake valves, and combustion chambers. The product claims to restore fuel economy and reduce emissions, improving overall engine performance.
Max-Clean's ability to clean and remove deposits from injectors and other engine components is a key factor in enhancing engine performance. Over time, engines accumulate deposits and contaminants such as dust, dirt, oil sludge, and carbon buildup. These deposits can restrict airflow, leading to a loss of power and reduced fuel economy. By removing these deposits, Max-Clean optimizes airflow, enabling better combustion and power generation. This results in improved engine performance and fuel efficiency.
The product also stabilizes fuel, preventing the formation of gums and deposits, especially during low-use and storage periods. This fuel stabilization further contributes to maintaining engine cleanliness and performance. Max-Clean is particularly effective in preventing Intake Valve Deposits (IVDs) and Combustion Chamber Deposits (CCDs). By preventing and removing these deposits, Max-Clean helps maintain engine performance, as IVDs and CCDs can cause a reduction in fuel economy and engine performance.
The impact of using Max-Clean can be seen in improved engine responsiveness, smoother idling, and increased mileage. Users have reported noticeable improvements in engine performance, with reduced hesitation during acceleration and enhanced power and fuel economy. The product is recommended for use every 10,000 miles or annually to maintain optimal engine performance.

Max-Clean's ability to restore fuel economy
Royal Purple's Max-Clean is a state-of-the-art synthetic fuel system cleaner and fuel injector cleaner. It deeply penetrates and cleans injectors, carburetors, intake valves, and combustion chambers to restore fuel economy and reduce emissions. Max-Clean also stabilizes fuel during low-use and storage periods, preventing fuel varnishing.
The oxidative stability of hydrocarbons in fuel impacts how quickly they chemically break down to form gums that stick to engine surfaces and bake into deposits. By delaying or preventing the onset of oxidation, fewer deposits are formed, reducing the clean-up burden of fuel detergents. This is how fuel stabilizers work synergistically with detergents to maintain total engine cleanliness.
Intake Valve Deposits (IVDs) are formed by oil seeping past the intake valve guide seals and down the valve guides. When the oil reaches the hot valve, it sticks and burns, forming carbon deposits. These deposits are very difficult to remove. As they accumulate, airflow into cylinders is restricted, causing a loss of power and fuel economy. Max-Clean prevents IVDs and optimizes performance.
Combustion Chamber Deposits (CCDs) increase the compression ratio of an engine and the octane requirements of the fuel. If the fuel's octane rating is insufficient to compensate for CCD buildup, it results in detonation and the build-up of heat/hot spots that damage head gaskets, piston rings, and rod bearings. Knock sensors in modern engines detect detonation and trigger the ECU to retard timing, reducing performance and fuel economy and increasing emissions. Max-Clean removes CCDs, relieves the octane increase burden, and restores performance.
According to customer reviews, Max-Clean has improved fuel economy, with users reporting smoother idling, quicker response, and increased mileage.

Max-Atomizer's injector flow rate improvement
Royal Purple's Max-Atomizer is a highly concentrated, high-performance fuel injector cleaner. It is specially formulated to solve problems with today's direct injection engines, but it can be used with any type of fuel injection. Max-Atomizer contains highly concentrated polyether amine (PEA) detergents that quickly clean clogged and coked injectors, restoring 100% of injector flow.
The injector flow rates are reduced when deposits form on the tips of injectors. Fuel Injector Cleaners (FICs) have the challenging task of cleaning and keeping deposit-sensitive injectors clean. The volatile low-flash-point detergents in most additives vaporize before reaching GDI injectors in extremely hot combustion chambers, especially in turbocharged engines. This results in incomplete clean-up and reduced injector flow.
Max-Atomizer improves injector flow rates and has been tested in BMW GDI turbo engines. Fuel economy is reduced when deposits are formed on injector nozzles. Modern engines have injector nozzles with a higher quantity of smaller holes. This reduces the fuel droplet size and better atomizes the fuel sprayed into the combustion chambers. However, smaller nozzle holes also clog more easily, especially in GDI engines that are more deposit-prone. Reduced fuel atomization causes a loss of power and fuel economy and increases emissions.
Max-Atomizer removes injector deposits and restores optimal injector atomization. It stabilizes fuel, especially before and after idle periods, to prevent deposit-forming gums. It improves injector flow by 94% to improve performance.

Max-Atomizer's ability to remove injector deposits
Royal Purple's Max-Atomizer is a highly-concentrated, high-performance fuel injector cleaner that is designed to remove injector deposits and restore optimal injector atomization. It is formulated to address issues with modern Gasoline Direct Injection (GDI) engines, which are more susceptible to deposit buildup due to their placement in the combustion chamber. This extreme high-temperature environment causes deposits to bake onto injector nozzles, making them challenging to remove.
The oxidative stability of hydrocarbons in fuel influences how rapidly they chemically degrade and form gums that adhere to engine surfaces, eventually baking into deposits. By delaying or preventing oxidation, Max-Atomizer reduces gum formation and, consequently, the accumulation of deposits. This, in turn, lessens the burden on fuel detergents, allowing them to work more effectively in maintaining engine cleanliness.
Max-Atomizer's unique formula utilizes a state-of-the-art Polyether Amine (PEA) detergent, which is specifically designed to tackle the challenges associated with GDI engines. Unlike other products that may contain Polyisobutylene (PIB), a dispersant with mild detergent-like qualities, Max-Atomizer's PEA detergent is a true detergent capable of actively removing stubborn coked GDI deposits. This superior cleaning ability has been demonstrated in controlled field tests, where Max-Atomizer outperformed its leading competitor in terms of injector flow rates, horsepower, fuel economy, and emission levels.
The effectiveness of Max-Atomizer in removing injector deposits has been validated by numerous customers who have witnessed improvements in engine performance, smoother idling, reduced hesitation, and enhanced fuel efficiency. It is safe for use in all fuel-injected engines, including those with sensitive components, and is compatible with a range of fuel types, making it a versatile and reliable solution for maintaining optimal engine performance.
