Do You Put Fuel Injector Cleaner In Before or After Gas?


Just like your car engine or tires, gas tanks are an essential component. However, you are likely to find it difficult to get a high car performance each time your fuel tank gets riddled with deposits. Tiny deposits can lead to mileage problems and this explains the extensive use of fuel injector cleaners nowadays. But one question still remains, do you put fuel injector cleaner before or after gas?

Most car manufacturers often recommend that you start by pouring fuel injector cleaners before the gas. Pouring fuel injectors before is likely to give you the best possible results: you are guaranteed to get a very homogeneous mixture.

In this article we are going to discuss in detail the best way to use fuel injector cleaner, whether you can add a fuel injector cleaner to a half tank, whether you can put fuel injector to a full tank, and much more. So read on to get the inside scoop.

When Should You Put Fuel Injector Cleaner in Your Car?

Fuel injector cleaners act as solvents that dissolve impurities found in the fuel and as a result, eliminates them through combustion. Impurities may vary and sometimes they can be additives found in the fuel.

In most cases, you will be required to put fuel injectors when your gas tank is almost empty or even half full! It is important to note that it is not a must to use them when the gas tank is almost empty. However, for the best results possible, almost empty gas tanks will ensure an effective mix with the fuel hence enhanced product chemistry.

What Is The Best Way To Use Fuel Injector Cleaner?

The good news is that most fuel injectors come along with detailed instructions from the manufacturers on how to use them. Using fuel injectors is quite easy. It is recommended to use them whenever you are around the gas stations, such that you can fill up your gas tank immediately after pouring it.

Here are some tips on how you can best use injector cleaners:

  • When using fuel injector cleaners, you must consider the quantity and how often you will use them. In most scenarios, the quantity to be used varies with the amount of gas in the tank.
  • Make sure the gas tank is almost empty. This ensures an even mixture between the fuel injector cleaner and the fuel.
  • Gently pour a suitable amount that fits the capacity of the car’s fuel tank. Make sure to re-read the instructions so that you don’t miss out on anything.
  • Once you are done with the contents of the fuel injector, top up the gas tank with your regular fuel fill.

Can I Add a Fuel Injector Cleaner to a Half Tank?

You can! There is nothing wrong with adding a fuel injector to a half tank. Be keen to use the right amount. A half tank means that the mixture will be even and will cause minimal damage to the car’s gas tank lining.

It doesn’t matter if you have a half tank, most fuel injector cleaners are combustible which can be burnt while the car’s engine is still running. Below are some of the reasons that you should consider using a fuel injector with a half tank:

  • Polyether Amine – A fuel injector component that can be used for both petrol and diesel gas tanks. If you have been driving for a while and your car is half-full, there is a likelihood that moisture has accumulated within the linings of the gas tank. This chemical will help remove the moisture and clears the old gas in the fuel tank blocking the fuel line hence preventing engine knock.
  • Polyisobutylene – This is another component with similar qualities as the one mentioned above. Commonly labeled as ‘PIB’.

Sometimes adding too much injector cleaners can cause damage to the gas tank linings as a result of the strong chemicals and additives. Perhaps the half-tank could be key in preventing such damages.

Can You Put a Fuel Injector Cleaner in a Full Gas Tank?

If you guessed yes, then you are right. While there aren’t any negative effects of pouring a fuel injector on the full gas tank, the components will take quite some time to mix evenly with the fuel.

However, we mentioned earlier that you are likely to get optimum results if your tank is almost empty.

Most car experts will also admit that most gas treatments work best when put before fuel before they burn up. They will likely recommend you to use fuel injectors during the fill-up process; this is simply effective compared to putting the injector chemicals and additives on top of the gas in the tank.
