We have to say that a great deal of negative opinion comes from owners of car shops who have a vested interest in you opting for a recalibration of the injection pump or replacement nozzles instead.
Here are a few things to take on board when you’re considering the issue of diesel injector cleaners…
Why Use Diesel Injector Cleaners?
Diesel is a particularly dirty fuel.
While it offers you many benefits, the carbon deposits and soot left behind can easily clog up your engine impairing performance and causing nasty emissions. Beyond this, an engine bogged down with these deposits will return worse fuel economy thereby negating one of the main reasons for buying a diesel vehicle.
So, by using a diesel injector cleaner as part of your maintenance routine, you can help to eliminate this problem without spending a fortune on mechanical bills.
What Do These Fuel Additives Do?
Diesel injector cleaners for engines are detergent additives that will enhance the quality of the fuel you use while also improving the combustion chamber.
As well as giving the injectors themselves a thorough cleaning, these additives also buff up the pistons, carburetor and other key components for a tune-up ride.
By cutting through the accumulated deposits, fuel injector cleaners can help to uprate the way your diesel car drives, cut down on smoke belching out the back while also optimizing fuel economy.
Do Fuel Injector Cleaners Actually Work?
In a word, yes.
Although opinion is polarized on whether or not this approach is the best method, few would claim that fuel injector cleaners don’t effectively solve the problems caused by diesel engines.
The difference is more easily noted in older diesel cars than with something new and up to scratch. This is perfectly understandable.
With the more effective cleaners, you can experience an improvement of 2-3% in your fuel economy which can add up to quite a difference over the course of the year.
Not only can these injector cleaners help to remove those niggling deposits, they also protect the fuel system and safeguard against future build-up.
As a final bonus, proper diesel injector cleaners can even extend the lifespan of the engine.
How Often Should You Use a Diesel Injector Cleaner?
These additives take effect while you are driving and the frequency of use depends on mileage rather than time.
Follow the instructions to see exactly how much of the cleaner you need to pop in. As a rule of thumb, you should add some more cleaner after 5000 miles.
Are All Diesel Injector Cleaners The Same?
They’re not, no.
While the majority of these additives are marketed in the same way, not all of them work as advertised so it certainly pays to do your due diligence.
If you take a chance on an additive then start to find problems starting your car, a worsening in fuel emission or any kind of corrosion, discontinue use.
Can a Good Fuel Additive Really Boost Performance?
It certainly can but good is the operative word.
If you choose your diesel injector cleaner wisely and make sure it’s the most effective additive for your particular car, you can definitely notice an upswing in performance.
Along with enhanced combustion and more ease when you’re starting your engine from cold, you could enjoy a small but noticeable boost on the power front.
We hope you’re equipped with a little more information about diesel injector cleaners for engines and you can now decide whether or not to give these additives a shot in your ride.
