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

    5.0 out of 5 stars One of the best fuel system cleaners

    B. · February 16, 2026

    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 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.

    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 Bolo’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.

    5.0 out of 5 stars Thanks Royal purple for making this part. There was a mail in rebate and a low price on this so i tried it and so glad i did.

    if you have a car that you are putting into storage for most of the year, buy a can of this and use it as directed. Drive your car long enough to get the Tank down to 1/4 tank or a bit lower. Then Pour a can of this into your near-empty tank and Immediately drive your car to the gas station and fill it up (the gas pouring down into the tank with the Max clean already added will cause it to mix Perfectly with your freshly pumped fuel). Then drive home and put your car in the garage for winter storage. Disconnect the battery and add a few extra psi to the tires (to prevent flat spots). And then come back 3-4 (or even 9-10 months') later and your car will start right up (and run smoother than ever). There is air above your fuel in the empty part of your tank so by storing your car with a full tank topped off you have pushed all the air that is above your fuel out of the tank (further slowing down the decay/deterioration of your fuel). Topping off your tank without "splashing your shoes" is the difficult part. :)The 1 question i have is: can this product (and should it) be used in combination with the Max Boost octane booster? or is it NOT ok to mix the 2 products?You used to be able to get 94 crystal clear Amoco Ultimate gasoline near my house at the gas station. Now you are LUCKY to be able to get 91 (or 92 if you are very lucky) crappy gas (that has been Further diluted with ethanol and water).If you read Car and Driver whenever they test Cars that absolutely reQuire high octane fuel (like the Nissan GTR) it preforms weak in their tests b/c of the unavailability of good quality 93 octane fuel. This is the United States of America folks. We basically can't get good quality fuel any more. The best available is BP 93 octane, but i have to drive kinda far to get to the nearest BP station from my house. It's all Wawa gas stations now with 91 or 92 10-15% diluted ethanol/water gasoline everywhere!I am investigating the use of The royal purple Max Boost to see if it helps with this problem of being able to get good gas anymore in America. And car and driver, if you are reading this: the next time you test the GTR (or a saleen Mustang, Cadillac cts-V) or any car that "must-have" 93 or better octane Fuel, try a can of Max boost. Or better yet, Test the car WITHOUT and then WITH a can of Max boost and see if the GTR puts out the advertised Horsepower and Acceleration numbers. If all you can find is 91 pump octane that is cut with ethanol and water, man what a waste of a $100,000+ sports car.

    5.0 out of 5 stars Pretty good

    W. · January 24, 2026

    Pretty good system cleaner. I felt my car ran a bit better after using it, but no real way for me to verify it. I have an older vehicle with about 150,000 miles and it seems to have worked well. The applicator tube is a good length, so no spills.Recommended.

    5.0 out of 5 stars Car ran smoother
