Diesel Injector Cleaner Information
As you may have noticed, diesel cars have exploded and become really popular all over the world. The reason for this is mostly caused by the better fuel economy and better torque, however, yes, with any good things do always bad things come. The diesel fuel is often pretty dirty and may cause carbon and dirt build ups inside the fuel system. This dirt may then come through the fuel filter and reach the fuel injector nozzles.
In most diesel cars, you have four cylinders and four fuel injectors. Inside the fuel injectors, you will find a small tip which regulates the amount of fuel that is flowing into the cylinder. Over time, there will build up carbon and dirt on these nozzles and cause the fuel injector to leak and flow too much diesel into the cylinder. As you may know already, too much diesel into the cylinder will cause black smoke from the exhaust pipe and this may be the first symptom you will see if your fuel injector nozzles are dirty.
But you should take in mind, these fuel injector cleaners are not only cleaning the fuel injector nozzles. You have a lot of other parts in your diesel fuel system like regulators, pressure and temperature sensors, pumps and all of these components needs a cleaning after a while.
There are now special injector cleaning fluids in the market which can be added to the diesel fuel and that fluid cleans the injectors and other parts as it passes from it with the fuel. These liquids are a lot less expensive than getting your injectors cleaned by a mechanic or replacing any other fuel parts. Also, the process is really automatic. All you need to do is mix a proportion of the liquid according to the amount of fuel or tank size and the rest your car will do itself. You do not have to use these only when there is a problem with your car. You can use these as a maintenance product to always make sure you have a clean fuel system. You may even save money in the long run by improving the fuel economy.
Coming to the fluid part, there are now so many brands which make these injector cleaners designed especially for diesel-powered engines and other diesel turbo engines which helps to thoroughly clean its injectors which helps to clear the way for fuel and recovers the spray pattern as well. But out of so many brands, which one is best for you? We have tested some common diesel fuel injector cleaners and sorted them in a top 5 list. Just check our list and read our review and create your own opinion about which diesel injector cleaner that will work best for you.
Diesel Injector Cleaner FAQs
It depends on a lot of different things. What weather conditions you live in and if you have a diesel or fuel car. Lucas fuel treatment is a really great product in our opinion.
These injector cleaners are nothing but special liquids made by special chemical blends which are not harmful to your engine components. The liquid works by mixing with your fuel in the tank and then being sucked in by the fuel pump and going forward towards the fuel rail and finally through the injectors into the combustion chambers. During its journey until the injectors, cleaning takes place. The liquid cleans signs of corrosion while in the tank, and cleans through the fuel line for carbon buildup and deposits.
All that is then flowing into the combustion chamber by the injector and finally blowing out from the exhaust pipe. Once cycle thoroughly cleans all the junk that may be residing in your fuel tank. While it passes through the injector nozzles, the nozzles also get cleaned up. That’s where most carbon is present which causes the black smoke, caused by uneven injector flowing. After all that is cleaned, the black smoke should be gone and the fuel flow has improved.
You can think of this liquid as a detox for humans and how it cleans the internal organs of a person. Just like that, the internals of an engine gets cleaned so that the engine may perform at its best.
Yes, overall these work and clean all kinds of diesel engines. However, it’s always recommended to read the manufacturers instructions and manual of how to use it and on which car you should use it on. It’s not always recommended to run these on too old diesel engines, because they may contain too much dirt and carbon build ups inside the hoses, which you actually want to be stuck there. If there is too much dirt inside the hoses, what happens if you pour in a cleaner? Yes, these small dust parts will come to lose and may fill up your fuel filter, or even pour up the fuel injectors even worse. The best way to use these is to use it as a maintenance liquid and pour it into your tank periodically to always make sure that your fuel system is clean.
It depends on what you are going to use the fuel injector cleaner for. If you think you can solve serious problems with the diesel injector cleaners you have to think again. These can’t fix any mechanical damages, the thing these fuel injector cleaners do, is to clean the fuel system and the fuel injector nozzles from any dirt or carbon build-ups. These diesel injector cleaners are pretty cheap and it could always be worth a try to pour it into your tank and see what happens. However, if you are trying to fix a mechanical or electric trouble code with these, it will most likely not work very well.
These diesel fuel injector cleaners are made for diesel engines and it’s not recommended to pour it into your gas tank. Actually, we have not tested this, because it may end up in very expensive repairs and it may also harm your engine. There are special fuel injector cleaners for petrol engines out there on the market and it’s really recommended to use one of these instead of experimenting yourself in your own car.
To use these injector cleaners, the best way is always to read the instruction of the product you purchased. However, the most of these injector cleaners work the same way. Just open the bottle and pour in the diesel injector cleaner into the fuel tank and start it up and drive for a while.
How much you should use is totally depending on the product. There is not always very easy to calculate how much you should mix, as it could be difficult to know how much fuel you have into your tank. The best way to calculate this is to check in your repair manual or call your authorized dealer to know exactly how much litres your fuel tank is when it’s almost empty. By knowing this, the calculation becomes a lot easier and you can just pour out the tank before pouring in the diesel injector cleaner. You can either drive until the tank is almost empty or let a mechanic pour it out for you. Some fuel injector cleaners require that the tank is full instead, and to know this you should always follow the manufacturer’s instructions.
It’s recommended to not pour this in your tank if you know that your car will stand parked for a long period of time. What will happen is that this can clean up too much in the fuel tank and may fill up the fuel filter when you are starting your car. However, it’s never a good idea to let a diesel car stand parked for a long period of time with diesel in the tank, depending on where you live. In many countries, we have some kind of biodiesel which do have both good and bad sides. A really bad side with this fuel type is that if you let it stand for a long time, it will start growing inside the tank and create small pieces in the whole fuel system. These pieces may gather into the fuel filter and cause your car to stop. I have even seen cases where you had to replace the whole fuel system because it was sludge everywhere in the system.
So the conclusion of this, you should never let your diesel car stand with diesel or diesel injector cleaner for a long period of time. Make sure that you at least start it up and let it run once in a while our pour out the diesel from the tank before letting it stand parked for a long time.
A common problem a lot of people have is to not maintain their cars if there is nothing noticeable fault on the car. This may result in expensive repair costs and it would have been much cheaper if they maintain it from the beginning. The thing is the same with these diesel fuel injector cleaners, they can’t repair any mechanical problems inside your fuel system. The best way is to use these fuel injectors once in a while to keep the fuel system cleaned at all the time because dirt can cause permanently damaged to your fuel system.
If you are trying to use these fuel injector cleaners because your car is already broken or running very rough, it may already be too late. You should probably have started to use these injector cleaners once in a while longer before. However, these injector cleaners are pretty cheap and it could be worth a try even for serious problems with your fuel car.
There are a lot of things to remember from this article, so we made a small summary of the most common parts to remember when it comes to fuel injector cleaners. These things are:
- These diesel injector cleaners will not repair your mechanical problems.
- Use these once in a while to make sure that your fuel injector system is always clean.
- There are other special fuel injector cleaners for petrol/gas engines.
- Always follow the instructions from the manufacturer of the injector cleaner.
