The Fuel Injector Cleaners I Recommend to My Customers


Fuel injection occurs when fuel is introduced into an automotive engine by way of a fuel injector. These are small electromechanical devices that atomize gasoline into particles that can be forced through a small nozzle. As time progresses, deposits from burning fuel begin to buildup in your fuel system. When this buildup occurs, and the fuel injectors get clogged, the amount of fuel that enters the cylinder is greatly compromised, which result in poor mileage and overall poor car performance.

The use of low quality fuel is a basic cause of clogged fuel injectors. It is important for the car owner to remember that not all gasoline is created the same. The lower the quality of fuel, the less detergent, less effective fuel additives are in the gasoline. Unfortunately, lower quality gasoline is always the least expensive, and is frequently chosen by motorists. Symptoms of dirty, clogged fuel injectors include: hard starting, rough idle, decreased gas mileage, high emissions.

The following fuel cleaner reviews are representative of the best on the market, and ones I wholeheartedly recommend. All of these cleaners also come with high customer satisfaction ratings, and will do just what their manufacturers claim, and then some. The end result will be a vehicle with improved overall performance.

The first cleaner on my list is BG 44K. BG 44K is fast when it comes to cleaning out your fuel injectors, valves and combustion chambers. This cleaner is the most expensive on our list, but it is also the some efficient on cleaning out your engine. It not only cleans your fuel injectors, but it also goes after the intake valves, ports, fuel filters and the combustion chamber. This product actually cleans your entire fuel system. After using this product there will definitely be a marked and notable increase in improved miles per gallon. This product is not only the one I recommend, but it’s also very easy to use.

Lucas 10013 Fuel Treatment is manufactured with a blend of oil, additives and detergent and will clean the carbon from the combustion chamber as well as the lubricating carburetors, fuel injectors and valve seats. It neutralizes low sulfur fuel issues, while increasing power and miles per gallon. Using this product will cause a noticeable increase in miles per gallon.

Fuel injector cleaners are a necessary part of proper car ownership and maintenance. In fact, anyone who asks the question on how to keep your engine running smoothly, will surely come across resources on how to clean fuel injectors.  Fuel injectors are responsible for spraying the correct amount of fuel into your engine, it’s as simple as that. When fuel injectors cannot function up to their optimal level your engine will begin to stutter and your mileage will suffer. When your fuel injectors are cleaned properly, your car will regain much of it’s lost performance, get better gas mileage and have lower emissions. Indeed, research has shown that regular maintenance can reduce up to 80 percent of all sulfur deposits. All of these products represent excellent choices depending on what you are willing to spend and your specific needs. We personally recommend, however, that you use the BG 44K. However, if you have budget constraints cleaners such as Lucas and Chevron will do quite nicely.
