How Do I Choose the Best Fuel System Cleaner?

If you're a proud owner of a motor vehicle, one of the most important things to keep in mind, maintenance-wise, would be to make sure that your car's bowels are functioning properly. Cars, in general, can be affected by a wide variety of infective diseases, and the effects can be rather substantial if these are left untreated. First of all, your car's performance will go down as a hefty amount of mucus, ehrm, fuel leftovers and a collection of greasy substances start building up. Eventually, the car's tubing and injectors, among other parts, can get clogged and the car can stop working altogether.

That would be the worst case scenario—alternatively, you may experience decreased acceleration rate, poor performance on the road, as well as progressively worse fuel consumption. Aside from being supremely annoying, all of these factors can also be quite costly, so getting around to fixing them can be a great way to save money and also improve your driving experience. One of the easiest and most efficient ways to clean a clogged-up fuel system is to introduce a healthy amount of fuel system cleaner into your fuel tank, and let it do its magic!

In this buying guide, we'll mention a couple of factors indicative of a tough means of destroying that bowel grease in your car, so that you can pick it up yourself, and hopefully resolve your automotive problems in a jiffy! First of all, one of the most important parts of a well-operating fuel system is the fuel injector, as this little piece of hollow metal is directly responsible for getting the fuel into the cylinders. These wee buggers get all greasy and clogged after awhile, since they are in constant contact with the fuel, which isn’t always of the cleanest and purest kind. As a result, an injector can't inject as much fuel into the engine as it’s supposed to, which in turn means less power and poorer acceleration.

A liquid such as the fuel system cleaner is capable of cleaning all of that up, and enhancing some of the car's worsening stats! Acceleration, fuel consumption, and overall power of the motor can all be subject to massive improvements, which is not only great on its own, but can also save you a fortune in the long run. Well, okay, perhaps not a fortune, but even if it's a hundred bucks a year—we're talking about four brand new hats! Or maybe a cordless drill, those are hot nowadays—it's up to you, really!

Another thing worth mentioning would be the preventive work of these likeable plastic vials. Namely, introducing them into your car's system can be greatly beneficial when it comes to reducing hydrocarbon and CO2 emissions, a great asset for an environmentally-conscious person! Perhaps one of the most feel-good things about these fuel system cleaners, though, is the fact that they’re able to give you back some of that horsepower you lost over the years. Imagine if somebody just gifted you a couple of horses out of the blue—you would be pretty ecstatic, wouldn't you! We at TopProducts were once mistakenly sent a gerbil, and were so happy that two of our best Internet browsers had weed themselves!

While we're talking about the matters of moisture, we'd like to highlight that all the fuel system cleaners we've found come in a liquid state, and you use them by simply pouring them into your fuel tank before you take a ride. So, to wrap it all up, fuel system cleaners have a relatively low cost, can repair your engine, gift you with horsepower, and save the polar bears! What's not to love, right?

Once you've taken care of your car, you can proceed to take care of your backyard. We at TopProducts have some great news for you! Namely, we have, completely incidentally, made a bunch of reviews for exactly the sorts of products one might need to rejuvenate their garden: barbecues, bug zappers, and cat repellents! If you happen to be in need of any of these products, feel free to consult our reviews!
Price
The pricing of fuel system cleaners mostly depends on the packaging, that is their amount, and the brand in question. Since pretty much all manufacturers producing these liquids claim that their products can offer a thorough and all-inclusive cleansing of the system, there doesn't seem to be that much variation when it comes to what a fuel system cleaner can do.

That being said, some versions boast properties such as corrosion and oxidation-resistance, which is a great property adding a couple of bucks to the overall price. If you want to save some money, you can also get yourself a big package of six (for example). One of these should have you covered for a long time, so if your finances are a concern, buying big might be a great solution—as opposed to buying a cheap version, which probably won’t give you the results you need for very long.
Features
We at TopProducts firmly believe that even the most rugged muscle car V8 needs a bit of care and grooming every now and then. Therefore, we've devised a top 5 list of the best fuel system cleaners money can buy, and in this section, we'll list some of the most important features to pay attention to before you make a purchase!

The list of the most important features to take into consideration when buying a fuel system cleaner:
  • Fuel Economy Improvement
  • Size of the Bottle
  • Horsepower Retrieval
  • Rough Idling Prevention
  • Corrosion Inhibiting
  • EPA Compliance
  • CARB Compliance
  • Stabilizing Fuel
  • Cold Start Performance
  • Safety of Use with Oxygenated Oil
All in all, a bottle of fuel system cleaner with a well-rounded mix of engine-cleaning ingredients can really be a lifesaver in the long run, especially if you're looking for a budget-friendly solution!
Construction and Design
Even though some of the bottles containing the precious engine-invigorating liquid do possess quite weird designs, more often than not they feature the same shape. After all, a bottle is not really a product that would need some special attention on the part of the manufacturers.

Nevertheless, some have ventured to make theirs look like the fuel nozzles we commonly see at gas stations. This facilitates the pouring of the liquid into your fuel tank, and it also looks a bit cheeky, which perhaps earns it a couple of extra points with some of the more fashion-oriented customers!

As for the mixtures that actually go into them, they tend to vary quite substantially between various manufacturers, so make sure to read the contents that are printed out on the back of the bottle.
Performance and Ease of Use
Using a fuel system cleaner is probably the easiest maintenance job in the world. Once you get ahold of one of these bottles, all you need to do is unscrew its cap, pour it into your fuel tank, and voila!—job done. Of course, before you proceed to do that, please read the ingredient list that comes with it to ensure that you don't end up using a mixture that’s not compatible with your car or its fuel system.

Other than that, make sure to safely store the bottles away when you're not using them and you should be alright. Hopefully, this review helped you decide upon what sort of fuel system cleaner to buy for yourself. Good luck with your purchase!
