THE IMPORTANCE OF FUEL QUALITY

Changes in the anatomy of diesel fuels according to all major engine manufacturers, as well as changes and new complexity built into modern diesel fuel injection systems now demand the use of good quality additives and fuel filtration.

The problem for the end user is distinguishing between high quality additives and the many low quality products that can be found on retail shelves across the country. Allow us to tell you more about all the important details and learn more about how fuel additives can benefit you specifically.

Proper diesel fuel filtration is critical to maintaining optimal diesel engine performance and longevity. Diesel engines are precision machines, and even the smallest contaminants in fuel—like dirt, water, or rust—can cause significant damage to fuel injectors, pumps, and other critical components.

Effective fuel filtration ensures that only clean fuel reaches the engine, preventing blockages, reducing wear and tear, and optimizing combustion efficiency. By maintaining high standards of fuel cleanliness, you not only enhance engine reliability but also extend service intervals, reduce maintenance costs, and improve overall fuel efficiency.

WHY FUEL ADDITIVES CAN MAKE THE DIFFERENCE.

Today’s advanced diesel fuels and engines come with their own vulnerabilities.

  1. The extreme heat that modern diesel engines produce can cause fuel to break down, form carbon deposits, and gum up engine and fuel system components. This causes losses in fuel economy. Using biodiesel can aggravate this.

  2. In extreme cold, ice and wax crystals can form, clogging your fuel system and reducing power and fuel efficiency

  3. Stored diesel fuel deteriorates, losing potency and causing sludge-like substances to form

These must be addressed to maintain fuel economy, remove contaminants, and eliminate harmful deposits that damage engines and fuel systems.

DSG Power Systems’ 4+ Fuel Additives excel at this.

DSG’s diesel experts have worked on diesel engines for decades. DSG services them, takes them apart, and rebuilds them. They see first hand the damage that can occur. They develop fuel treatments to solve real problems.
