Fuel Injector Cleaner Benefits

Does fuel injector cleaner work? What are the benefits? Is it worth adding to your gas tank? In short, when used regularly, fuel cleaners work. They can help remove harmful deposits, prevent new deposits from forming, and enhance vehicle performance.

 

Fuel additives can improve gas mileage, reduce long-term maintenance costs, and they’re affordable.

 

The quality of gasoline varies because some gas only meets minimum federal standards while other brands meet higher fuel standards as part of the Top Tier fuel program. Therefore, the amount of carbon buildup inside an engine also varies. This is where a fuel injector cleaner comes into play.

What Are Fuel Injectors and Cleaners?

Fuel Injectors and Impact on Gas Mileage

Before we answer the question, “What are injector cleaners?” we should briefly talk about fuel injectors. For those who aren’t sure, fuel injectors have a small nozzle that sprays fuel into an engine’s cylinder. Pump gasoline can cause carbon deposits and corrosion over time, clogging your fuel injectors. Clogged injectors can lead to poor performance AND decrease your fuel mileage.

 

When you consider today’s high cost of gas, increasing fuel mileage even slightly can make a difference to your wallet. Let’s look at a hypothetical scenario. Suppose your vehicle has a 20-gallon gas tank, and you’re currently averaging 25 MPG. Now, suppose you could add 2 MPG by using a quality fuel cleaner. Do the math; instead of getting 500 miles on a tank of fuel, you’re now getting roughly 540 miles!

 

If you fill up once a week, that difference equates to more than 1,000 extra miles over a full 26 weeks (one year). That’s money that stays in your pocket!

 

The difference in fuel economy will vary. Again, the example above is merely hypothetical to illustrate the point. Some people might see a bigger boost while others might only enjoy a more minor increase in MPG. Nevertheless, a small boost is better than nothing.

What Are Injector Cleaners?

Dissolvents vs. Detergents

So, what exactly are injector cleaners? It should be noted that fuel injector cleaners typically fall into two categories: dissolvents and detergents. Polyetheramine (PEA) is a dissolvent. It breaks down carbon deposits and impurities in fuel lines, pumps, injectors, and more without leaving residue behind. It’s a potent ingredient. They blend the best fuel injector cleaners with PEA.

 

Whereas dissolvents break down and dissolve carbon deposits, detergents force those deposits to detach and exit the fuel system. There has been some debate on detergents’ effectiveness and ability to remove deposits efficiently.

 

A good fuel injector cleaner can help improve gas mileage, vehicle performance, and lower maintenance costs by keeping the engine clean. A clean engine delivers more power and better performance because it doesn’t have to work as hard.

How Well Does Fuel Injector Cleaner Work?

As has we mentioned, fuel injector cleaner works. However, the degree to which it works varies. It’s based on variables such as the quality of the gas, age and condition of the engine, and other factors.

 

To remove heavier, long-term deposits from your vehicle requires a higher concentration of additive than what is present in pump gas.

 

Some pump fuel brands add small amounts of fuel injector cleaners in their gas. You should use a Top Tier fuel coupled with a good fuel system cleaner to ensure that your injectors are free of deposits. When should you use a fuel injection cleaner? A good rule is each time you change your oil.

 

You can add a fuel system cleaner at regular intervals to help prevent mechanical issues, or if you notice problems with rough idling or irregular combustion.

 

Diesel has even more properties that need protection compared to gas-powered engines, which is where a good diesel injector cleaner can help.

 

The good news is that injector and fuel system cleaners are affordable. Therefore, it won’t hurt to add them as part of your scheduled maintenance plan.

How To Use Fuel Injector Cleaner & The VP Difference

There’s really nothing to using fuel injector cleaner. For best results, make sure your gas tank is nearly empty. Pour in the desired amount of fuel injector cleaner, and then fill your tank with gas. That’s it!

 

Many injector cleaners call for an ounce of product per gallon of gas. Be sure to read the label before using.

 

VP Racing has blended specialty fuels for nearly 50 years. We’ve used our fuel expertise to create several high-quality additives that clean injectors and the entire fuel system.

 

If you’re shopping for the best fuel system cleaner, try VP Fuel System Cleaner with RP21. It has advanced cleaning agents that thoroughly clean the entire fuel system for up to 5,000 miles. It’s engineered with a leading-edge PEA detergent that gets deep down to clean pistons, rings, and valves, even under severe operating conditions.

 

It helps eliminate knocking and pinging, reduces the harmful effects of ethanol, and cleans carbon and varnish from fuel system components. It keeps your engine running well.

 

We also design VP 7-In-1 Fuel Treatment. It’s a premium gas additive for 2 and 4-cycle gas engines. For maximum results, use it between intervals of our Fuel System Cleaner to boost octane, stabilize fuel, and clean injectors.

 

7-In-1 removes deposits from the combustion chamber, keeps your fuel injectors, pistons, and valves clean and in top shape. You’ll feel the difference in your ride after treating one tank of gas.

 

Spending a little money now to keep your fuel injection system clean regularly will pay off down the road.
