What is The Best Fuel System Cleaner? Review of the top 3 Brands

I am sure some of you miss the good old days of manual cars that used carburetors inside the engine. While it might have been easier to figure out, the carburetor type of engines was not friendly to mother earth.

To comply with the emissions law, auto manufacturers came up with the fuel injection system. This modern technology has been present in our automobiles since the 1990s.

While it proved effective at reducing pollution from cars, the system is expensive and complicated. With the aging of your vehicle, carbon becomes a residue in both the engine and the injectors that power the fuel.

Unless you find a way to remove the carbon build-up, you’ll find yourself spending more money on gas as your miles per gallon stats continue to worsen.

The invention of the fuel injection system gave us the ability to accelerate faster, while also helping the environment by creating much less pollution, as compared to the old carburetor engines.

The primary culprit can be traced to the type of gas you’re using. Some of those cheap gas stations you frequent have bad fuel that will have a negative impact on your car’s performance in due time.

If you’re in the habit of thinking all gas is created the same, you’re sadly mistaken. Low-quality gasoline is manufactured with less detergent or less effective fuel additives.

The clogged fuel injectors in your automobile are powerful enough to compromise the atomized spray pattern required for an excellent burn rate once the spark plugs are ignited.

The way you drive can also be a contributing factor. If you tend to accelerate fast, most likely you’re sending more fuel through the fuel injectors than it’s required, which helps to increase the carbon residue.

The older your car gets, the more carbon that’s built up and that is why it is recommended you clean out your engine fuel system every 25,000 to 30,000 miles.

If you fail to heed this warning, you’ll just be spending more money on gas as your engine slowly deteriorates. Gas guzzlers are usually created from neglect to clean the fuel injection system on a regular basis.

You should know that if your fuel injectors are clogged and dirty, you’ll experience more unwanted emissions as your car misfires and develops engine problems.
