What is it with fuel cleaners? Some drivers and mechanics recommend regularly using cleaning products to improve the vehicle’s performance. Others say the cleaners do nothing or make things worse, forcing you to replace the old or worn-out fuel system part. Do fuel injector cleaners work?
Do Fuel System Cleaners Work As Promised?
While fuel cleaners generally work, the effectiveness of individual products can vary widely. There are also some things they cannot do, such as fix damaged fuel injectors. They can, however, remove carbon deposits and improve fuel flow, which can improve the engine’s performance. If you plan to use a fuel cleaner, you’ll probably be better off with a polyetheramine-based (PEA) formula.
What Is A Fuel Cleaner?
Also called fuel system cleaner and fuel injection cleaner, it’s a cleaning product that removes contaminants in the fuel system and engine.
What Does The Fuel Cleaner Do?
A fuel cleaner removes contaminants in or on parts that carry fuel from the tank to the engine. Eliminating the unwanted residue and by-products of various processes allows the cleaner to restore the fuel system and engine to running like new.
Today’s vehicles use a fuel injection system to supply gasoline or diesel to the internal combustion engine. The system uses injectors to deliver the exact quantity of fuel needed for the ideal air-fuel ratio.
A faulty fuel injector can add the wrong quantity of fuel to the air-fuel ratio, making the engine run rich or lean. If the issue involves contaminants like carbon, the injector might become clogged, reducing the fuel sprayed into the engine or cutting off the supply entirely. The engine will operate at reduced efficiency or potentially fail to start from the lack of fuel.
Unfortunately, carbon and other contaminants can appear and accumulate anywhere in the fuel system. Once the by-products have built up on a part, such as one of the fuel injectors, they can prove difficult to remove with ordinary cleaning methods. Carbon deposits can interfere with and damage the affected parts, reducing your vehicle’s fuel economy and performance.
Picking the Right Fuel Cleaner For Your Car
There are numerous fuel injector cleaner products available, but not all of them do the same thing. If you use a fuel cleaner that isn’t suited for your vehicle’s specific needs, you might end up with a subpar or negative outcome.
Avoid issues by choosing the right fuel cleaner. Here are some things to look for:
Compatibility With Your Vehicle
Some fuel cleaners are formulated to work with specific engines. Using them on incompatible vehicles might lead to issues. Always ensure that your chosen cleaner is compatible with your vehicle’s engine.
Older vehicles have engines that use carburetors instead of fuel injectors to blend air and fuel into the correct mixture. They require a fuel cleaner formulated for use with a carburetor.
Active Ingredients
Check the fuel cleaner’s list of active ingredients. You’re looking for either polyetheramine (PEA) or polyisobutene (PIB). These additives are tailor-made to efficiently clean contaminants like carbon deposits and varnish in the fuel system and engine.
If you want additional benefits, like lubrication, look for a fuel cleaner that includes those additives.
Cleaning Potency
Finally, consider the strength of the fuel injector cleaner that you need. The higher the product’s potency, the more effectively it cleans contaminants. However, highly potent cleaners also cost more.
How Do Fuel System Cleaners Work?
Most fuel cleaners contain carefully formulated chemical additives that do the heavy lifting. Some active ingredients target carbon deposit build-ups while others lubricate surfaces.
Polybutene amine (PBA) is one of the most common active ingredients. Other examples include PEA and polyisobutene PIB.
These active ingredients are detergents that act as surface active agents or surfactants. They form micelle structures that pry dirt away from surfaces and capture the latter for disposal. The two surfactants are particularly effective against carbon deposits.
Why Should You Use A Fuel Injector Cleaner?
Here are the benefits that fuel cleaners bring to your vehicle:
Efficient Fuel System and Engine
Parts like the combustion chamber and fuel injectors can benefit from regular cleaning. Carbon deposits get in the way of their operation, so removing the contaminants enables the fuel and engine parts to function properly.
Improved Fuel Efficiency
The fuel cleaner also contributes to fuel efficiency. Clean injectors can work precisely and without delay, delivering the right amount of fuel at the right time. Meanwhile, a clean combustion chamber can burn the air-fuel mix more completely, generating more power while minimizing the unburned fuel. Your vehicle can get more mileage out of its fuel and will run more smoothly, making your driving experience more pleasant.
Lubrication and Protection
Many fuel cleaners also have lubricating additives that apply a layer of lubricant to the surfaces they clean. Lubrication reduces friction between moving parts, preventing overheating and reducing wear. The lubricating layer also makes it more difficult for carbon to get a grip on the protected surface, slowing down the deposit build-up.
Longer-Lasting Parts
Parts don’t only work better when they’re clean. They also last longer because they don’t have to overcome issues like clogging, overheating, and metal-on-metal contact. These problems wear out the affected part, so preventing them extends the part’s service life.
