Diesel vehicles are known for their robust performance and ability to surpass the owner’s expectations. However, diesel fuel presents some challenges that periodically may require an additive.
Diesel fuel contains hydrocarbons and additives. When these two elements enter a dirty injection system, the injectors will restrict. This will affect the flow rate of the injectors as well as how well the fuel atomizes and distributes.

Symptoms Of A Dirty Injection System
There are different types of diesel fuel.
Diesel fuel injection systems can develop deposits and sludge within the injectors. Debris and a buildup of carbon can also present problems. When this happens, your vehicle will have trouble accelerating, may not idle smoothly, and have difficulty with cold-starts. Stalling and decreased gas mileage often occur as well.
Injectors act as a mechanism that releases fuel through an atomizing mist into the engine. This creates what’s called combustion. Dirty injection systems prevent proper combustion resulting in the engine not being fed the appropriate fuel to function correctly. If the dirty injectors are not cleaned out, the entire system and engine can easily become damaged or fail.
Taking preventative measures by using a fuel injector cleaner can literally save your vehicle! Fuel injector cleaners vary in how they are designed to perform. Some will clean the entire injection system whereas some partially clean some components. Lubricants in the cleaners coat the injection system to remove deposits and to prevent wear and tear.
Professional mechanics that are familiar with diesel fuel injection issues will recommend using a fuel injector cleaner first. After doing so, if you notice your vehicle returns to its normal operating vigor, then you can be confident the system needed the cleaner. However, if you find that the vehicle has not improved, it may be time to have a professional look at it. A mechanic may need to disassemble the injectors and employ various methods to clean them out.
Things To Look For In Diesel Fuel Injector Cleaners
There are numerous injector cleaner products on the market that basically all perform in the same way. When purchasing a cleaner, base your selection on the criteria we discussed earlier on what to look for in a cleaner. Use that information as a guideline in selecting what product is best for you and your vehicle.
Some of the products are not designed to work in winter seasons; however, if you live in a warm climate where the temperatures rarely drop below 30 degrees (F), there are no worries. You can confidently use the cleaner without fear of it becoming gelatinous in your engine.
If after looking over our recommendations, you are still scratching your head not quite sure what to get, we have narrowed down our “best of the best” to the top-three.
