## Overview

Royal Purple 18000 Fuel Injector Cleaner is a concentrated, fully synthetic formula designed to restore injector flow by removing deposits and carbon buildup. Compatible with gasoline and diesel engines, it maximizes horsepower, improves fuel economy, and stabilizes ethanol to prevent engine damage. Trusted by enthusiasts and professionals alike, it ensures smoother idling, quicker starts, and long-lasting fuel system health.

## 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.

## Questions & Answers

**Q: Hi! Which is the diference between this and the other "maxclean" from royal purple? Thanks btw!**
A: Good question. We bought both and it seems that they truely do the same thing. Both very effective making cat coverter and fuel injector cleaner. I can tell and see the difference. Royal Purple is top of its game 5☆.

**Q: How does this differ from MaxClean?**
A: More like a direct/specific fuel injector cleaner.

**Q: how do you use this? what gas to mix with?**
A: Direction is on the can.  What I did was, wait for your gas tank also empty then I put it in then fuel up the gas.  Run it for 10, 15 minutes or more for it to clean out the injectors.  Hope this help.

**Q: how does this compare to sea foam cleaner?**
A: Seafoam is meant for marine motors. That's why it's called seafoam. Don't use it on yer car. That stuff is horrible. This, redlines SI-1 complete fuel system cleaner and of course techron by chevron. Techron IS what chevron calls their PEA which is what you want to clean out your fuel system. All 3 contain PEA. Seafoam doesn't.
