CleanBoost® Maxx™ 08oz Fuel Treatment for Gas & Diesel Fuel - Treats 240 Gallons

Made my car run like new, much more consistent power delivery and much better gas mileage after one use. Gas mileage went from 35 to 40 highway and from 26 to 28 city, amazing for a Mercedes’. I used on my Toyota Camry with 130k miles and it made the car so much quicker like when I first got it and a tank of gas last longer. My girlfriend who used to fill up the Toyota once every two weeks, we are 3 weeks in and she’s above quarter tank, I didn’t even tell her that I put this stuff in and she noted smoother engine, easier cold start and the gas gauge needle not going down as quickly. The common theme for both of the cars is restoring the horse power to like new conditions and muuuch better gas mileage. I went ahead and replaced the spark plugs and air filter for the Toyota and it runs as smooth as silk compared to before. If you have a high mileage car, I recommend running this fuel treatment for atleast two tank fills, spark plugs, filter change, and oil change with a quality oil with good detergents to clean the engine and boom, like new engine.

i used in old bike and on trip,we use this and have good performance w/ maxx

After watching a very compelling video online about this products efficacy, showing a good increase in horsepower. I purchased a bottle and did 3 fill ups using this product. There was zero improvement and mileage actually dropped a small amount. Taking into account the vehicle used in the video was an older vehicle, then I suspect this is a terrific fuel injector cleaner, nothing more. My car is a 2024 Subaru Outback W/Turbo, with less than 3000 miles, so injectors would not be dirty.So perhaps an older vehicle this might work ( pretty darn expensive injector cleaner )But would not purchase for fuel mileage benefit.

Of course after being skeptical I had to try the stuff out.I guess it's a lot of factors on a really if you know how your car accelerates and if you always keep track of your gas mileage with that being said I have a 2007 Honda Accord with about 100,000 miles on it I did definitely feel when I accelerate it was much smoother .I'm guessing 90% of people wouldn't notice but it did have a slight increasing horse power also.for the gas mileage information on this I think it did slightly go up normally I get about 30 miles per gallon in with the stuff I swore I was getting 33 I know there's a lot of factors involved in that so I'm still going to keep testing and checking my gas mileage but so far I put on 1000 miles with this stuff in my tank.

I Started using this product for my Honda civic and it works great!Ive seen better acceleration and gas mileage. The seller is helpful and works really fast at answering customers questions. I recommend buying this product 100%. You won’t regret it !!!!!

Product is great but needs a longer neck to be able to pour and not waste.

My MINI has 30K miles. It is very well maintained. As expected on a car like this MPG is about the same, but emissions and Engine noise both are much lower after CleanBoost treatment. Feels like the Timing chain is on summer holidays which is great news cuz thats the weakest point this engine has.If I had a Toyota with the same mileage, I bet it would work like new literally forever.This product is recommended for everyone. In worst case scenario it will act as a fuel stabilizer which you should be using anyways unless you wash your tank every 3 months. Plus it's very cheap. 1 bottle = ~240 gallons of fuel.Now for the cons: in some cases check engine might light up. So far in my case it was caused by O2 sensor in cat, which prolly got triggered when a big chunk of carbon buildup came off the cylinder head. btw you can clean a sensor with carb cleaner it work just fine. Other one was caused by an exhaust valve, which again was prolly caused by a big junk of buildup coming from the valve or cylinder, which made the travel distance longer (since theres no more buildup anymore) before the ECU managed to adapt to it.Anyway, I cleared the codes and everything is running fine for more than a week now.Last but not least a cheat sheet for Metric system:1ml treats 3.7 Liters1 Liter needs 0.27ml of treatment5 Liters needs 1.4 ml55 Liters needs 15ml45 Liters needs 12ml30 Liters needs 8ml20 Liters needs 5.5ml15 Liters needs 5ml12 Liters needs 3.3ml10 Liters needs 2.7mlTotal 236ml (8oz) bottle can treat ~875 Liters.P.S. Based on PEA studies, the equilibrium between build-up and cleaning is reached at 10k miles of constant use. This basically means that max result is reached after 10k miles of constant use.

I use this product in my 1991 Toyota Celica GT and my 2014 BMW 328 xi. I usually add two measures of the product to a full tank of gasoline. Definite difference in power, especially in the Celica (which is iIMHO, underpowered) I've also noticed a small increase in MPG in the BMW. Highly recommended!
