Which Is The Best Fuel Injector Cleaner? – The TOP 10

It’s common knowledge that a vehicle needs fuel to drive; however, most people aren’t aware that there is a vital component that dictates how efficiently their vehicle uses fuel: the fuel injector.

Which Is The Best Fuel Injector Cleaner?

A fuel injector disperses fuel into the motor. When the vehicle changes speeds, the fuel injector regulates the amount of gas that reaches the motor. In order to function properly and use gas efficiently, the fuel injector MUST be clean.

The following 10 fuel injector cleaners will ensure this crucial car part is operating properly and that your vehicle is using fuel efficiently.

Red Line Complete Fuel System Cleaner

One of the very best fuel injector cleaners is Red Line Complete Fuel System Cleaner. What really sets this product apart is that as wellas actually cleansing your fuel injector it helps to prevent the buildup of carbon deposits, moisture and other gunk afterwards.

Many fuel system cleaners utilize synthetic ingredients, such as manmade oil, or PEA purity; however, not all of them list the type of ingredients they contain. With Red Line Complete you know exactly what you are getting. That’s because they verify that the amout of PEA (polyether amines content) used is between 30 and 50 percent. Red Line confirms this amount using Material Safety Data Sheets (MSDS), something that most other manufacturers that create fuel system cleaners simply don’t do, which makes it very hard (and in some cases impossible) to determine the type and quality of the ingredients that are used.

Red Line’s Two Step Approach

As mentioned, Red Line Complete Fuel System Cleaner uses a two step approach, which is unique for a fuel injector cleaner. It both cleanses the fuel injector and prevents the buildup of moisture, carbon deposits and other debris. The synthetic blend of ingredients that are used in this formula reduce abrasion on the fuel system, the pump, the carburetors and the entire engine.

Not only does this formula use a one-of-a-kind lubricant (that is designed to lubricate the upper cylinders), it also uses ingredients that are able to work in both high and low engine temperatures. This makes it a very flexible product that can be used in any type of vehicle, and one which offers great results. It also offers excellent results for the treatment of combustion chambers and intake valves.

Instructions for Use

Using this popular fuel injector cleaner is pretty easy too. Simply add the entire contents of the bottle to your fuel tank when it is close to empty every 3,000 miles. After it’s added, refill the tank with up to 20 gallons of fuel. For routine maintenance, add half a bottle when your fuel tank is nearly empty every 1,500 miles.  That’s it!

Best Fuel Injector Cleaner – How They Work

Fuel isn’t as pure as it used to be. Today, several additives are applied to gas in order to boost its octane; ethanol, in particular. This substance both oxidizes and emulsifies gas, creating byproducts that are non-combustible, like carbon.

Over time, these by-products build up in a fuel injector. Eventually, this buildup prevents the injector from opening and closing properly. It can even lead to a leak in the nozzles that are located within the fuel injector. A fuel injector cleaner removes the buildup of these non-combustible substances (including carbon and other gunk, such as rust and varnish) from this vital component in your vehicle.

Using a fuel injector cleaner every 3,000 miles is highly recommended for all vehicles, but especially for any vehicle that uses gas that contains ethanol. There are many fuel injector cleaners on the market, but how do you know which one is the best? Obviously, the highest quality products provide the best clean, and they are able to do so by using the best ingredients. There are other factors that are also taken into consideration when determining what makes the best fuel injector cleaner, such as the amount of time that it works, how easy it is to use, and the cost.
