Max-Clean Fuel System Cleaner and Stabilizer 11722 20 Ounce

WORKS GREAT, I PUT IT IN WITH 1/42TANK LEFT DROVE IT AROUND TILL 1/4 TANK FILLED IT UP GAINED 2 MPG

This might be the best of the three top fuel system cleaners I use: Royal Purple made an almost instant improvement in fuel economy and acceleration in two of my vehicles, one an 18 year-old mini-van with nearly 200K miles and the other a newer CUV with almost 100K miles with a turbo. I also use BG44K and Chevron Techron. I always read and was told that Chevron was the "gold standard" in fuel system/fuel injector cleaners, but now I'm not so sure.

I would recommend this fuel treatment. It’s awesome. It really works 100% once again thank you seller.

My family and I have been using Royal Purple Max Clean Synthetic Fuel System Cleaner & Stabilizer for about two years now, and it works great. My brother, who is very mechanically inclined, recommended it to me — and he hasn’t steered me wrong yet! The product itself does exactly what it claims, and we’ve been very happy with the results. My only complaint isn’t about the product, but about Amazon’s shipping. The first bottle I received was missing the funnel that is supposed to come attached, which meant I had to send it back and wait for a replacement. For that inconvenience, I’m giving four stars instead of five. Other than that, this is an excellent product, and I would absolutely recommend it.

My Honda Accord has been already smoother and more powerful with a bottle of Royal Purple Max-Clean Fuel System Cleaner and Stabilizer. Fully satisfied!

Excellent fuel treatment to clean carbon buildup off the Valves and Cylinder heads. Highly recommended by professionals in video comparisons. This won 2nd place but does almost as well as the 1st place product that required several steps. I am happy with it. Made my 2024 Honda CR-V and wife’s 2013 Honda Accord run and idle better. Son also claimed his 2019 Ford Fusion was helped also.

Make sure you fill your gas tank. It is good to 10 to 20 gallons

I recently used the Royal Purple Max-Clean Fuel System Cleaner and Stabilizer (11722) in my vehicle, and I'm thoroughly impressed with the results. First and foremost, this product is easy to use. The 20-ounce bottle is convenient and provides enough treatment for several applications. Adding it to my fuel tank was a simple task, and it mixed effortlessly with the gasoline. One of the standout features of Max-Clean is its effectiveness in cleaning the fuel system. After using it, I noticed a significant improvement in engine performance. My vehicle's acceleration became smoother, and there was a noticeable reduction in engine noise. It's clear that this product helps remove deposits and carbon buildup, optimizing fuel combustion. Additionally, Max-Clean acts as a stabilizer, which is particularly valuable if you have a vehicle that sits idle for extended periods or if you want to improve fuel quality in areas with inconsistent gasoline formulations. It helps prevent fuel system corrosion and keeps the fuel fresh, which can lead to better overall engine health. I appreciate that Max-Clean is suitable for use in both gasoline and diesel engines, making it a versatile choice for a wide range of vehicles. While it's not the cheapest fuel system cleaner on the market, the results it delivers are worth the investment. Improved fuel efficiency, smoother engine performance, and long-term fuel system protection make Royal Purple Max-Clean Fuel System Cleaner and Stabilizer a product I would highly recommend to anyone looking to maintain their vehicle's performance and reliability.

Fantastic product.

息つぎが改善され吹け上がりが良くなった。 アイドリングが少し安定してる。 キャブ車におすすめです♪

Pues parece que si funcionó bien, hay muchos productos como este sin embargo si noté que la camioneta recobró cierta potencia. Lo recomiendo

I noticed a more smooth engine performance when I applied the Royal Purple Max-Clean into my fuel. I am still watching out for further improvements as it will take some time to fully realise the benefits.

This product gave me 11% extra mileage but it didn't remove check engine light.
