What is a gas cleaner?

If you have just purchased your first car and aren’t particularly knowledgeable about automobiles, the workings of an engine might seem somewhat mysterious. I won’t go into too much detail, but basically your run-of-the-mill 4-stroke engine works by pushing through a mixture of gas and air in a process of 4 strokes: the intake stroke, the compression stroke, the power stroke, and the exhaust stroke. It’s a complicated process which occurs and reoccurs thousands of times per minute.

Over time, gas deposits begin to collect inside the engine’s intake valve. These deposits then absorb gasoline as it passes into the combustion chamber, significantly decreasing the amount of fuel your car actually uses. As well as leaving you out of pocket, gas deposits negatively impact the performance of the engine and can cause lasting damage if ignored.

A lot of experienced car enthusiasts swear gas cleaners are the only way you can keep your engine performing to its highest standard without spending hundreds on a mechanic. A quality gas cleaner will remove all gum buildup from your engine’s intake valves and prevent any further deposits from accumulating, conceivably saving you hundreds of dollars in the long run.

Using a gas cleaner

Although gas cleaners are treated by some as a divine creation, using one is actually pretty straightforward.

The process of adding a gas cleaner to your car tends to follow similar steps, regardless of what brand you are using. Some gas cleaners may vary slightly, so it’s important to always read the directions before adding one to your car. Once you have gone through the instructions, pause to check your fuel to be sure you have at least the recommended amount in the tank. Once your fuel supply is equal to or above the amount suggested by the manufacturer, add the suggested amount of gas cleaner and start your car.

And that’s it! That is literally all you have to do to ensure your gas cleaner works to the best of its ability. It will be pushed through your engine as you drive, eliminating all gum accumulations and keeping your engine in tiptop shape.

Which gas cleaner is right for me?

Never buy a gas cleaner on impulse. You may find one that seems just like the thing you need to keep your engine running smoothly. However, do some online research and consult with others who have experience using gas additives before purchasing.

While there are more than a couple of brands of gas cleaners which will work perfectly with most engines, there are certain brands which are designed to be used exclusively with certain engines. We’ll look at some of those in a little bit. Hopefully, you’ll find the best additive for your vehicle’s engine.

But does it really work?

I don’t blame you for being skeptical about gas cleaners. Over the years, there have been so many “miracle” gas additives that ended up doing nothing at all. Some even made engines perform worse. If you are hesitant about trying an additive, it’s understandable. But let’s learn more to help you become more at home with the idea.

Perhaps instead of asking, “Do gas cleaners work?”, we should ask, “Which gas cleaners work?” There are more than a few manufacturers of gas cleaners which insist their products will remove all gas deposit buildups from your engine, only for them to prove totally ineffective. Thankfully, there is an equal, if not greater amount, of reliable gas cleaners that do exactly what they say they are going to do and more.

Granted, it can be a bit of a challenge separating less reliable gas cleaners from the gas cleaners you can trust. In order to determine which cleaners have established records of high-performance, you should meet with other car enthusiasts to hear about their experiences with particular brands.

Here’s a video of a YouTube user who took it upon himself to determine once and for all if gas cleaners actually remove those pesky gas deposits from your engines. It turns out, they can. If you have the time to watch the video, I urge you to do so. It’s pretty cool to see a gas cleaner in action.

Royal Purple Max-Clean Fuel System Cleaner and Stabilizer

Royal Purple Max-Clean Fuel System Cleaner and Stabilizer-5be9f767e32b3

As any car owner knows, staying within a budget while trying to carry out repairs can be difficult. If you’re looking for an inexpensive solution to gas deposit buildup, Royal Purple Max-Clean Fuel System Cleaner and Stabilizer is a good way to go.


  • Improves fuel economy: Gas deposits absorb fuel as it makes its way through the engine. This means that you end up using much less gas than you paid for, which is more than a little frustrating. This additive breaks up gas deposits, improving your fuel economy by as much as 3.2%.
  • Stabilizes fuel: If you didn’t guess it from the name, Royal Max Purple Max-Clean Fuel System Cleaner and Stabilizer also works as a fuel stabilizer. A fuel stabilizer should be used with seasonal vehicles, such as convertibles and boats prior to placing them in storage. Failure to use a fuel stabilizer can kill engines when they’re not in use.


  • Requires multiple uses: If you need a gas cleaner that is going to restore your engine to premium condition ASAP, you should probably stay away from Royal Purple Max-Clean Fuel System Cleaner and Stabilizer. While it will indeed return your engine to its former glory, it will almost certainly require more than one use to do so.BUY THIS ONE

  • Chevron’s image: In terms of this cleaner’s performance, there aren’t a whole lot of negative things to say. The major drawback of Chevron Techron Concentrate Plus is the fact that it bears the Chevron name. Chevron doesn’t have the best public image and has been accused of some pretty heinous crimes against the environment.

  • Depletes quickly: If you plan to use Red Line SI-1 on a regular basis, you’d better be prepared to drop some serious cash. For a complete clean, it is recommended that you use one 15-ounce bottle per tank, which will prove pricey if you’re planning on continual use.
