Fuel Injector Cleaners Buyer’s Guide


Why do you need fuel injector cleaner?

Fuel injector cleaner helps you to get the most efficiency from the fuel in your gas tank. It accomplishes this by removing and cleaning deposits that build up in your gas tank and the fuel lines leading to your engine. By keeping fuel injectors clean, you avoid any long-term damage and costly repairs.


What benefits can you expect from fuel injector cleaner?

Besides avoiding long-term damage and costly engine repairs, fuel injector cleaners can help to improve the smooth running of your car’s engine in both idle and rev. This improves the responsiveness of your throttle and helps your engine burn fuel more efficiently. The more efficient burning of fuel helps to keep your automobile running at its highest miles per gallon (MPG) rating, which saves you money with every tank of gas.


What is fuel injector cleaner?

Fuel injector cleaner is a mixture of solvents that can be added directly into your fuel tank. These solvents help to break down debris, sediments and other deposits that tend to find their way into fuel tanks from cheaper fuels or from setting in storage for a long time. Eliminating these unwanted elements in your fuel line prevents their buildup inside your fuel injectors where they have the potential to block fuel flow.


How does fuel injector cleaner work?

Fuel injector cleaner helps to dissolve the buildup of deposits in your fuel tank and fuel line. This is similar to a detox diet for your car. The solvents used to break down the debris, sediment and other deposits in the fuel you put in your car are burned up as they pass into the engine during the combustion process and are eliminated with other exhaust.


What ingredients should you look out for in fuel injector cleaners?

The most active ingredient utilized in any fuel system cleaner is a solvent known as polyetheramine (PEA). Without PEA in the formula, a fuel injector cleaner is close to worthless when it comes to dissolving the smallest and most destructive deposits most often found in your fuel line. Some cleaners are PEA free and their bottles are filled up with various types of alcohols, kerosene or other chemicals, which tend to cost less. Products without PEA can work to break up big chunks of carbon deposits and can be used on some older motors that are barely running, but to get true fuel injector cleaning performance, you will want to invest your money in a cleaner that contains PEA.


What’s the best injector cleaner for an older vehicle?

You have heard that age is just a number when it comes to fuel injector cleaner. Regardless of age, any vehicle that employs fuel injectors as a part of its fuel combustion system can benefit from fuel injector cleaner. Some automobiles manufactured in the 1980s and just about all cars before then used carburetion systems, which mean they did not have fuel injectors. Older vehicles that have a carburetor will not benefit from fuel injector cleaner.


What’s the best fuel system cleaner to fix a nonfunctional vehicle?

Fuel injector cleaners do not contain a magic formula for reversing the damage done to your vehicle through the buildup of deposits in its engine. Depending on the severity of the damage, manual cleaning of the fuel injectors, their replacement or a complete engine over-haul might be necessary to return your vehicle to working condition. The best use of fuel system cleaners comes in the area of damage prevention with regular use rather than as an attempt to undo the damage.


How often should you use fuel injector cleaner?

As a basic guideline, fuel injector cleaner should be used with every other oil change if you use the vehicle pretty frequently or at every oil change if you use it infrequently. It should be added to a gas tank that is nearly empty before fueling up in order to get the maximum impact out of the product.

With these questions answered, you should have a much better idea of how your vehicle can benefit from fuel injector cleaner, how it works and how it is best used. The reviews of top fuel injector cleaners below will allow you the opportunity to compare various formulas in order to make a well-informed decision when comes time to make your purchase.
