How to Keep Your Engine Clean With Injection and Fuel Systems Cleaner

Keeping your fuel system clean is something that every car owner has to do to ensure that the car keeps running properly and is problem free. If you do not keep up with cleaning the fuel system, which includes the fuel injection, you could be getting less gas mileage, emitting fumes and toxic vapours into the environment, and compromising the overall performance of the car itself. Performing the fuel system cleaning yourself saves you a trip to the mechanic and the bill that comes along with it.

You know when it is time to clean your engine's fuel system. There are a few telltale signs to look for. One is that the car seems to be getting less gas mileage over time. The other is that it has been over 25,000 miles since you last cleaned the fuel injectors. A good rule of thumb is to perform a cleaning every 25,000 to 30,000 miles to keep the fuel injection and fuel system from clogging up and causing problems later down the road. To clean your engine, be sure to properly prepare yourself for the job, and make sure to go through the correct steps after completion. Buy everything you need to keep your fuel system clean on eBay, including solvents and safety items.

Preparing to Clean the Engine

When it comes to a heavy duty maintenance job like cleaning the fuel injection and fuel systems, there are a few things to do to ensure you are prepared before starting. Once you begin, you do not want to stop, so it is best to get everything you need set up in advance.

Your Safety

Before you clean the engine with fuel systems cleaner,, it is a good idea to prepare yourself and keep yourself safe. You will be using chemicals, so it is always a good idea to protect your face and hands before touching and inhaling any harsh chemicals. You may want to wear safety goggles, long-sleeved clothing, or even some type of thin safety gloves to keep your skin from coming into contact with the chemicals. Solvents are also flammable, so keep that in mind when working on your car with these types of chemicals.

Supplies and Environment

It is best to do projects like this away from any heat sources; inside in an open area with good ventilation. Gather the items you need to perform the cleaning, which involve the actual injection and fuel systems cleaner, tubing, and a screwdriver or a wrench. It is easier and faster to purchase a fuel injection cleaning kit, which should include everything you need for one low price, instead of having to purchase items separately.

Cleaning the Fuel Injection System with Fuel Systems Cleaner

You have to disable or disconnect the fuel pump before you begin, and remove the car's gas cap to avoid a combustion situation. Then, you have a couple of options for the next step. You can either plug in the fuel return line, or hook up the tubing to the fuel outlet to create a pathway for the fuel to run back to the tank to avoid coming into contact with chemicals. This is to ensure that no gas gets to the engine during the process, because the fuel injection cleaner is highly flammable. If you are having a hard time locating the fuel injectors, your vehicle's manual should provide the necessary information.

Then hook up the pressurised cleaning chemicals and allow them to run their course through the fuel injection system. At this time, you can start the car's engine, and run the cleaning solvent through the fuel injectors until it is finished. This should take anywhere from five to ten minutes. When it is done, turn the engine off if it does not turn off on its own, once the cleaner has run its course.

Finishing Up

Now you need to hook the equipment back up. Reset the fuel pump and reattach it, put the gas cap back on, and reconnect everything else including the pressure regulator. Consult the manual if you need assistance in reconnecting the car's equipment. Ensure everything is connected properly before starting the vehicle again.

Listen for Sounds

Start the car and listen carefully to the engine. Make sure nothing sounds odd or out of place once you start the engine, and let it run for a few minutes to determine if the car's performance has been enhanced by the fuel systems cleaner.. You should see immediate results from the cleaning. If your car's performance is not vastly improved, there may be a bigger problem involved.

Take a Test Drive

The best way to see if the car is improved is to drive it. It is alright to take a test drive immediately after the cleaning, as long as all of the equipment is hooked up and properly working. Drive the car for a few minutes as you normally would, and listen and look for problems. Sometimes if a car has other issues, the issues are not resolved with a simple fuel injection cleaning.


For a car that has not had the fuel system cleaned in awhile, some significant clogs may be present. This situation may not be resolved with at home fuel injection cleaning, and may need to be taken to a professional mechanic. This home service, when done properly at least twice a year or more, can help reduce costly trips to the mechanic. If problems are still present after you clean the fuel system yourself, a more extensive cleaning process in which the fuel injectors actually have to be removed from the car and cleaned by a professional may be in order.

This process cannot easily be done at home like using the fuel systems solvent can. For minor issues and regular maintenance, however, using injection and fuel systems cleaner to keep your engine running well and your car getting great mileage is a smart option.

When to Perform a Fuel Systems Cleaning and Other Maintenance

There are a few factors to look for and guidelines to follow to know when your car needs maintenance such as an oil change, fuel systems cleaning, petrol tank cleaner, or other maintenance to ensure that your car keeps running well over time. Paying attention to your vehicle, its gas mileage, and its performance keeps you on top of maintenance, and saves you money from costly car repairs in the future, if you allow the car to go too long without regularly scheduled maintenance.

Type of Maintenance

When to Perform It

Do It Yourself or Use a Mechanic

What to Use

Fuel injection cleaning

Every 25,000 miles

When car's performance start to decrease

Lowered gas mileage and performance

Do it yourself unless it has been over 30,000 miles and large clots or other problems may be possible

Fuel injection cleaning solvent, tubes

Fuel injection cleaning kit

Oil change

Every 3,000 miles or three months

Either; cheaper to do yourself

The kind of oil your car is used to for the make/model of your car and what type of performance it has

Petrol tank cleaning or additives

If you notice a loss of power when accelerating

There is no get-up-and-go when you press the gas pedal

Do it yourself; works as you drive the car

Mix the fuel cleaner with a certain amount of gas; then follow the instructions carefully to see how much cleaner to add

The type of cleaner you desire

Some cleaners have additives such as detergents, lubricants, antifreeze, or other ingredients to meet individual needs

Keeping track of the maintenance your car needs ensures that you will have less mechanical problems over time, and your car may end up running for a lot longer than you planned. Taking proper care of your car, including performing regular oil changes, petrol tank cleanings, and periodic fuel injection cleanings are affordable and time saving. The money spent on these cleaning products is less than what a trip to the mechanic costs if you avoid these important services and maintenance items.


Whether you are proficient at car repairs or a novice, performing your own fuel injection cleaning can be simple and save a lot of money. There are even some additives that you can simply pour into the gas tank to perform a basic cleaning when you do not want to do the entire fuel injection system cleaning. This can be a time saving way to keep your car running at its best and save money on additional trips to see a mechanic. Using fuel injection cleaners and cleaning the system yourself should not intimidate you. If you follow the instructions given on the package and use your car's manual in conjunction, the process should be simple.

Keep an eye on your car to make sure it is performing right, and as soon as things start to look like they are declining, perform a cleaning to get things going again properly. This ensures your car will last for years to come, and fuel systems cleanings should be as common as oil changes and other regular car maintenance.
