Max-Atomizer™ Fuel Injector Cleaner
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.

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.

The best thank you you saved my car
-
I use the product as preventative maintenance so my vehicles are running excellent already and I don’t notice any difference. However this is a quality product at an affordable price and that is way it’s part of the regular maintenance on my vehicles.
-
This gave a noticeable boost in performance for a 21 Mazda cx-5 turbo w 70k miles. Recommended.
-
It worked! Reduced my cylinder 1 misfires to single digit. Will try another bottle.
-
Very good product for engine code 0420, recommend 1/4 gas put this product and run 5miles, add full tank gas( highway prefer)
-
Wow, this actually works! Wife’s turbo Sonata was getting a rough idle and a little hesitation on acceleration. No trouble codes found. After reading reviews I took a chance, filled tank and added this Royal Purple. Within 20 miles idle smoothed out, NO Hesitation on acceleration now. Same results on friends and family vehicles. Highly recommended!

Purchased two bottles for our suburban. Cylinder 1 had a bad misfire. Swapped coil and plug wire from another cylinder – same result. Tried another brand of injector cleaner – same result. Was going to take it for an injector replacement, but decided to give it one more try with 2 bottles of the royal purple from Canadian tire. Our tank was under 3/4s. Well after about 200 km of driving to our cottage, the misfire is gone. Everything is good. Highly recommend this product. Cheaper than a mechanic working on it.
-
It improves responsiveness and reduced knocking noises after first use. Literally felt the difference within the first mile of fill up. My 10.5 year old Ford Focus has over 227K miles. I’m impressed with the improvement.
-
Prior to using this, my car was averaging around 26-28 MPG on the highway (using mid-grade gasoline). After using this, my car was averaging over 30 MPG. I’ve used others before, but never had results like this! Well worth the extra money!
-
I’ve used Royal Purple previously. The product doesn’t claim fantastic results which other products may. Your 4 banger won’t turn into a road rocket. But improved fuel economy, smoother idling and quicker response are all there.
