The person who invents the diesel fuel is college passed and know what they are doing. The money spend on additives is always a wasted money.
This view is quite short sided. It doesn’t consider the amount of new science forced on engine makers and oil companies.

How Fuel Injector Cleaner Works
Most of the cars have typical combustion engine in which gasoline is heated that produce the energy and it powers your vehicle’s engine.
When it burns, it can’t transfer the solid matter into energy but it releasing stored energy within whatever you’re burning.
When the gas is burning then most of it released from exhaust pipe but some of them is still there.
Same as like when we were creating a coal by burning woods.
When gas is burning in your engine to produce energy and release carbon using exhaust pipe but some of them are still their and deposit inside your engine and fuel lines.
This deposit reduces air flow that is necessary for the engine to work efficiently.
The engine works by using the mixture of gasoline and air to create a specific combustion reaction and deposit works with it.
As they are working for years so it can cause many problems like reducing fuel economy, rough idling, smoke and reduced much power. Now it’s a time to clean up.
When we are cleaning it manually so it is much unfavourable and time taking.
Thanks to companies that made a clear-cut mixture to remove that carboxyl deposits with the name of Polyetheramine or also called PEA.
Best Injector Cleaner for an Older Vehicle
As we heard most of the times that age doesn’t matter. It is same in the circle of cars. Most of the new cars that have direct injection system require more cleaning than any other system.
