Your lifeline to freedom may just be your car, but there are compounds and debris that are working to shorten the life of that car. One of the biggest villains when it comes to this is the fuel you use to get the car to move. Over time, the gas breaks down, leaving gum, varnish, and even corrosive materials.

All of these can affect the performance of your car, but luckily, there are products that can help you reduce or negate these compounds left by your gas. One of these is the Royal Purple Max-Clean Fuel System Cleaner and Stabilizer.

In the sections below, we will be taking a deep dive into what makes this formula so good. So without further ado, let’s take a look at what this product has on offer.

Royal Purple Max-Clean Review


Royal Purple Max-Clean has been around for a long time, and it has kept many people’s cars in good shape. It is a 3-in-1 product that not only cleans the engine but also stabilizes the gas that you put in it.

The product is crafted to help boost fuel efficiency and power output, as well as reduce emissions released by your car. All of that can benefit most cars regardless of the gas that is put in it.

Who is This Cleaner for?

When it comes to this product, it can be used on many engines and will benefit their performance and longevity. For those looking to figure out where this formula will shine the brightest, the answer may just be motorcycles. This 3-in-1 formula is perfect for stabilizing motorcycle fuel, no matter what type it is.

That is just one user who will benefit from using this formula. Another user who can get a lot from this product is anyone who has multiple engine types in their life. This formula is compatible with a lot of different gasses and engines, so it is very versatile.

What’s Included?

When you purchase this product, you will end up receiving the following:

  • Royal Purple Max-Clean

Overview of Features

  • 3-in-1 fuel additive
  • Designed to improve fuel economy (3.2% on average)
  • Increases HP (2.6% on average)
  • Reduces emissions (12% – 18 % on average)
  • Decreases engine knock and pinging
  • Stabilizes fuel

When it comes to optimizing the ability of your engine, there are several options to choose from, but one of the best has to be Royal Purple Max-Clean. This formula works well with multiple vehicles, which gives it a versatility that not every cleaner and stabilizer gives you. It is easy to use and is crafted to make sure that compounds and dirt left behind are not a problem in the engine of your car.

With all that being said, there are a few concerns to be aware of. There are some vehicles that it isn’t well suited for, such as capless gas vehicles or hybrids. Plus, although it is priced fairly low, some feel that the value doesn’t seem to match the price.

How to Use Royal Purple Max-Clean

There are a lot of ways to get the most out of this formula. The best way, though, is to use it per the instructions on the can. If you need more information on this, make sure to check out this in-depth video below.


If you are looking for a formula that gives more consistent results, then you will want to find an alternative option to the product we have been looking at. Luckily, we have combed through the choices and found an option that will calm all those concerns – the STA-BIL 22275 formula.

Though this product works primarily on the same engines and with the same gasses, it works harder to stabilize fuels. By choosing a formula that does this, you will help reduce build-up in the engine and protect the engine from potential corrosion.

Both of these features give this formula a single-mindedness when it comes to the benefits it offers the car owner. Plus, you can use this on multiple fuel-powered units, including lawn care equipment.

Final Thoughts

Making sure your car’s engine is working to its fullest and at the highest level of efficiency is vitally important. There are many tools to help you do this, and one of these is Royal Purple Max-Clean. It is versatile and designed to do multiple jobs, but it is by no means perfect. Hopefully, our review has helped you determine if this product is the right one for you and your vehicle.
