It restores full injector flow, optimizes fuel spray patterns, stabilizes ethanol, and enhances horsepower and fuel economy for gasoline and diesel engines. Trusted by enthusiasts and professionals alike, it delivers noticeable, long-lasting engine performance improvements with every use. ## 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. Review: One of the best on the market - I've tried most of the commonly available products like this on the American market. The majority are snake oil and do nothing to improve gas mileage or clean the fuel system. Prior to Royal Purple, I tried Amsoil PI which is more expensive but did work exceptionally well. I later learned from a master mechanic that unless these types of products have an additive package containing PEA, they likely won't do much which explains the lackluster results from the other products, and also why the Amsoil PI did work so well. In comes Royal Purple to my door and I have to say it does work at LEAST as well as the Amsoil, at a slightly lower price and easier to find. Royal Purple does contain the additive package and you can really tell the difference after running it a full tank. My 2016 NIssan Maxima now has more pep from a dead stop, is getting a few MPG better mileage and to my surprise it quieted a bit of engine noise. I can really feel the performance boost. This will be a go-to product for me after each oil change. Review: Wow this actually works! - I am generally very skeptical about these miracle cure in a bottle products but this royal purple atomizer worked remarkably well for me. I had noticed a decrease in fuel mileage, rough idle and an overall lack of performance in a 2.3 liter GDI engine. Also the fuel trims were off quite a bit. After one bottle and a tank of gas, the difference it truly remarkable. The idle is perfectly smooth and there is a noticeable improvement in performance. I expect fuel mileage will improve as well but too early to tell. Fuel trims are spot on. I had forgotten how wonderful this engine performs! Will this fix all problems, certainly not but it absolutely made a huge improvement to GDI fuel injectors. ## Features - Restores fuel economy - Stabilizes ethanol - Maximizes horsepower - Improves responsiveness - For use in both gasoline and diesel engines - Fit type: Universal Fit ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00XF03K54 | | Best Sellers Rank | #1,961 in Automotive ( See Top 100 in Automotive ) #10 in Fuel System Cleaners | | Brand | Royal Purple | | Customer Reviews | 4.6 4.6 out of 5 stars (3,199) | | Date First Available | May 8, 2015 | | Is Discontinued By Manufacturer | No | | Item Weight | 6 ounces | | Item model number | 18000 | | Lift Type | Power | | Manufacturer | Royal Purple | | Manufacturer Part Number | 18000 | | Model | 18000 | | OEM Part Number | 18000 | | Product Dimensions | 2 x 2 x 7 inches | | Special Features | Concentrated | ## Product Details - **Brand:** Royal Purple - **Item Form:** Spray - **Material Feature:** Unscented - **Scent:** Unscented - **Specific Uses For Product:** Fuel Injector ## Images ![18000 Fuel Injector Cleaner - 6 fl. oz. - Image 1](https://m.media-amazon.com/images/I/51z8yQJUDKL.jpg) ## 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 5β˜†. **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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ One of the best on the market *by L***H on January 6, 2026* I've tried most of the commonly available products like this on the American market.
