Royal Purple® 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 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 to restore maximum injector flow. This optimizes injector spray patterns and better atomizes fuel as it enters the combustion chamber. The result is improved fuel economy, enhanced power and performance, reduced emissions, smoother idle, and quicker / easier starts. Max-Atomizer is the only fuel injector cleaner that also stabilizes ethanol, which chemically breaks down to cause harmful effects to an engine.

RECOMMENDED TREAT RATE
Pour entire contents of bottle into nearly empty tank immediately before refueling, then install fuel on top of additive. Minimum recommended dose is one (1) 6oz. bottle to 20 gallons of fuel. The maximum effective dose is one (1) 6oz. bottle to 10 gallons of fuel.
RECOMMENDED USAGE
For best results, use at every fill-up.Minimum recommended usage is every 3,000 miles.
Injector deposits form quickly in modern Gasoline Direct Injection (GDI) engines because injectors are located in the combustion chambers. This extreme high-temperature environment cokes (bakes) deposits onto injector nozzles, making them difficult to remove. Even a small amount of deposit on injector tips prevents optimal atomization of fuel, causing performance loss and reduced fuel economy. Max-Atomizer’s high flash point allows it to reside in hot combustion chambers longer than other products, resulting in more effective deposit clean-up.

Injector flow rates are reduced when deposits form on the tips of injectors. Fuel Injector Cleaners (FIC’s) face a tough task of cleaning/keeping-clean deposit-sensitive injectors. 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 when 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 fuel droplet size and better atomizes fuel sprayed into combustion chambers. But smaller nozzle holes also clog easier, especially in GDI engines that are more deposit-prone. Reduced fuel atomization causes loss of power and fuel economy, and increases emissions. Max-Atomizer removes injector deposits and restores optimal injector atomization when tested in BMW GDI turbo engines.

Oxidative stability of hydrocarbons in fuel impacts how quickly they chemically break down to form gums that stick to engine surfaces and coke (bake) into deposits. By delaying/preventing the onset of oxidation, less gums are formed, resulting in fewer deposits. This reduces the clean-up burden of fuel detergents. In this way, fuel stabilizers function synergistically with detergents to maintain total engine cleanliness. Max-Atomizer stabilizes fuel (especially before/ after idle periods) to prevent deposit forming gums.
