Description

Royal Purple’s Max-Atomizer is a fully-synthetic, 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, restoring 100% of 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.

    • It worked on my Infiniti Q40
I just purchased a used car and when I got it I was experiencing stuttering when accelerating. I thought to get an injector cleaner to try it out and this one popped up. I put it in with 10 gallons of fuel as stated, and the next day I saw a difference in power and throttle response. I will be putting Royal purple in my car every 3,000 miles without question. ... show more

    • Works Good on old Jeep
Great product to use in older vehicles or to keep newer vehicles running smoothly. Cleans out the gunk left behind by the ethanol in our fuels. Cheaper than Auto Parts and big blue box store.
