7 Of Best Fuel Injector Cleaner Review


If you have a car, then you know as much as I do that fuel efficiency is key. What you may not know is that the amount of fuel a car uses is regulated by a fuel injector.

True to its name, a fuel injector releases fuel into your car motor. When your car is changing speeds, it is the fuel injector that is regulating the amount of gas reaching your motor.

Being keen on my car’s fuel consumption has enabled me to come up with ways of enhancing fuel efficiency; a good injector cleaner is key.

This best fuel injector cleaner review aims at helping you choose an injector cleaner for fuel efficiency.

What Does Fuel Injector Cleaner Do?

Compared to a few years ago, fuel is less stable as a chemical today. Reason being, ethanol is being used as an octane-boosting substance; this alcohol emulsifies and oxidizes to create non-combustible byproducts such as carbon.

The build-up of these products can block your car’s fuel injector making it not to open or not to close or can cause a leak in the nozzles of your fuel injector.

If you use the best fuel injector cleaner, these non-combustible substances – carbon, varnish, gunk, and rust – are broken down and minimize their buildup in your car’s system.

It is advisable that every driver uses a bottle of fuel injector cleaner every three thousand miles, especially those that use gasoline that has ethanol.

Fuel injector cleaners are judged based on their cost efficiency/relative price and their cleaning potency (which will be determined by its ingredients). However, factors such as ease of use and length of productive life also come into play.

When Should You Use Fuel Injector Cleaner

We all like to look after our cars; to ensure everything is working in order, the car is clean and presentable, and it gives a smooth drive. However, sometimes it is the stuff we think less about that end up damaging essential parts of our cars. Fuel, for instance, acts as the source of energy that powers your car. Before it is burned to power the car, it passes through a couple of components. Today, fuel comes with more contaminants than before. These contaminants coupled with byproducts of combustion result to harmful deposits that can clog the engine reducing its performance. The effects of contaminants are gradual and may go unnoticed especially if the engine is strong. Nevertheless, when left for long, they may cause huge damage to the engine system. The performance of your car’s engine can be compromised in 2500 kilometers or less. To this end, the use of a fuel injector cleaner comes handy. Use a fuel injector cleaner when your car develops a starting or hesitation problem, experiences rough riding, does not accelerate smoothly or produces more than normal amount of emissions. If you are an experienced driver and you know your car, you will feel the decrease in performance. You can remedy all these issues before they occur by following fuel system cleaners’ recommendations; most advise that an injector cleaner is used every 3000 miles. Vehicles that have been idle for a few months or a few years will need the best fuel injector cleaner before getting back on the road.
