Fuel Injector Cleaner Specifications: What do They Mean?

Fuel injector cleaners are a key part of regular automotive maintenance. You don’t have to use fuel injector cleaners often, but it is important to use them. Fuel injector cleaners are cheap, and easy to use, and you can easily use them yourself, rather than going to a mechanic. And the benefits are nearly endless.

Using a fuel injector cleaner can dramatically improve the quality of your ride. It can make your drive smoother, more powerful, and more responsive, while eliminating sputtering and hesitating. It can increase the health of your fuel system and engine, which can save you repair money, while also increasing the resale value of your vehicle.

However, when you purchase a fuel injector cleaner, it can be a little confusing. All of the products have a variety of descriptions and specifications on them, and it can be hard to know exactly what is being advertised. In order to get the right fuel injector cleaner for you and your vehicle, you need to know exactly what the product is. To help you with that, we’re going to describe all of the different specifications that are listed on fuel injector cleaner bottles, so you know what you’re getting, as well as what you’re not getting, with any fuel injector cleaner that you’re considering.

Cleans injectors

Of all the specifications on this list, this is the one that, in one form or another, you’ll find on every bottle of fuel injector cleaner. Because ultimately, this is describing the primary purpose of fuel injector cleaners: to clean fuel injectors.

Fuel injectors are responsible for spraying gasoline into the car’s engine. There are numerous fuel injector nozzles in each engine, and they get dirty as a build up of dust, dirt, and other detritus begins to block them. Fuel injector cleaners help break down those contaminants, so that your fuel injectors are clean, and functioning properly. This is important, but also something that you’ll find on every fuel injector cleaner that you look at.

Cleans carburetor jets

Carburetor jets are, essentially, a variation of fuel injectors. Every car has either fuel injectors, or carburetor jets. While fuel injectors are responsible for spraying gasoline into the engine, where it combines with oxygen, carburetor jets handle things a little differently. Carburetor jets take a mixture of gasoline and oxygen, form it into a mist, and spray that into the engine.

Same concept, but with a different execution. And just like with fuel injectors, carburetor jets can develop dirt and dust build ups, which keep the jets from functioning efficiently. Any product with this description will clean the carburetor jets, and get the fuel system working well.   

Removes deposits

Most parts of your vehicle develop deposits over time. Your fuel system is no exception. Deposits – be they dirt, dust, grime, or carbon – will show up in your fuel system. Deposits occur not just in your fuel injectors and carburetor jets, but also in your fuel valves, fuel filters, and numerous other places.

Fuel injector cleaners that advertise that the remove deposits will break down and dissolve deposits throughout the fuel system. That way, the contaminants won’t stay in the system to clog your injectors and jets, and won’t get moved into the engine where they can cause more serious damage.

Stabilizes fuel

A cleaner that stabilizes fuel is useful if you might be leaving the gasoline in your car’s tank for a long period of time. Funky things happen to gasoline when it sits around for a while, and fuel stabilizers keep that from happening.

Fuel stabilizers remove water from the fuel, and also prevent corrosion, which can be a serious issue when gasoline has been sitting around unused. They also keep rust, gum, and varnish from occurring. With a fuel stabilizer, the gasoline in your engine will stay fresh – nearly good as new – usually for up to two years. A car with a fuel stabilizer will be able to start up immediately, even if it hasn’t been driven in months.

While fuel stabilizers aren’t that important for most fuel injector cleaners, since you’ll likely be driving your vehicle, but it still helps remove water and prevent engine damage.

Lubricates cylinders

Engines require lubrication; that’s what motor oil is for. Even though you have motor oil, though, doesn’t mean you can’t get extra lubrication from elsewhere. Fuel injector cleaners that advertise cylinder lubrication provide exactly that: extra lubrication for your engine’s cylinders. This complements the motor oil in your car, which can prolong the life of your oil, keep your engine running smoothly, and decrease engine temperature. It can also provide you with a little bit of a safety net if you end up low on motor oil.

Quite simply, your engine cannot get enough lubrication. Adding some directly to your cylinders through your fuel system can help the happiness and health of your motor.

Adds fuel lubricity

Fuel lubricity might sound like a fancy term, but it’s a very simple concept. Fuel lubricity only really applies to diesel engines, though. In vehicles with diesel engines, the diesel fuel is used as part of the lubrication process for the motor. Diesel fuel has to have some lubricants in it to help keep the engine properly cared for.

Diesel fuel naturally has a lot of lubricity, but much of it is removed in order to make the fuel up to legal regulations. So additives should be added to many diesel vehicles, to keep the engine lubricated, so it doesn’t have excess heat and wear and tear. A fuel injector cleaner that adds fuel lubricity will do exactly that.

Increases power

This one is pretty self-explanatory. A fuel injector cleaner that says it increases power does exactly that. By cleaning out the fuel injector nozzles, the vehicle can get the correct ratio of gasoline to oxygen, which maximizes the performance of the engine. By doing this, the car can gain as much as 2 to 3 percent more horsepower, which is far from insignificant.

A fuel injector cleaner with this description is a must for anyone with a high-performance vehicle, or who has noticed a decrease in their car’s performance.

Restores mileage

Just as fuel injector cleaners can improve engine performance in a fun way, they can also increase engine performance in a practical way. By cleaning the fuel injector nozzles or carburetor jets, and sending the correct amount of gasoline to the engine, the car can get maximum efficiency out of its engine. As such, fuel efficiency can increase by 3 to 4 percent, which can save you a lot of money at the gas tank. Needless to say, this is one of the more important descriptors on a fuel injector cleaner.

For diesel and/or gasoline

Diesel fuel engines and gasoline engines have different needs. Some fuel injector cleaners address the needs of the former, while others only address the needs of the latter. And some can be used with either type of engine.

If a fuel injector cleaner doesn’t specify what types of engine it’s for, then you should assume it’s for an engine that requires gasoline fuel. Most of the time, however, it will be listed on the bottle.

Compatible with 4-cycle and/or 2-cycle engine

There are two basic types of engines: 2-cycle and 4-cycle, more commonly referred to as 2-stroke and 4-stroke. The basic difference between the two is that the a 2-stroke engine requires two strokes of the piston to complete the combustion cycle, while a 4-stroke engine requires four.

All modern vehicles are 4-stroke engines. 2-stroke engines are primarily only used for appliances (such as lawn mowers and tractors), small boats, and small bikes. If a fuel injector cleaner states that it’s only for 2-cycle engines, you shouldn’t use it for your vehicle.

Rejuvenates stale fuel

The longer that fuel sits in a vehicle, the worse it gets. Water begins to develop in the fuel, and it gets stale, just as a soda would. One way to take care of this is to drain the fuel system and add fresh gasoline to the car. Not surprisingly, that’s a lot of work. The easier way is to rejuvenate the stale fuel. A fuel injector cleaner with the description that it rejuvenates stale fuel will pull the water out of the old fuel, and help bring it back to life. The vehicle should then be able to start relatively easily, and drive somewhat smoothly, which it wouldn’t have been able to do before.

Complete system

A fuel injector cleaner that says it has a complete system is basically stating that it does more than just clean the fuel injector nozzles. A complete system fuel system cleaner will not only clean the fuel injectors, but the fuel valves, fuel filters, and numerous other elements within both the fuel system, and the engine as a whole. This descriptor essentially means that the fuel injector cleaner cleans the entirety of the fuel system, not just one element of it. If you’re looking for a comprehensive cleaning, then this is a good specification to search for.

Conclusion

Fuel injector cleaners can serve a lot of different purposes. And different types of fuel injectors can serve different purposes. Knowing what the specifications and descriptors in fuel injector cleaners mean can help you find the product that is best for you and your car.

Using a fuel injector cleaner can make your car drive better, give it better gas mileage, keep it in working order, and save you a lot of money. With this guide, you can know exactly what you’re getting when you purchase a fuel injector cleaner.
