A Tell-All Guide to Ultra Low Sulfur Diesel

All diesel is to be used in non-road diesel engines have to be ultra-low sulfur diesel.

Preventative maintenance has always been important for any operating system, especially in life-saving emergency power systems. Recently, EPA regulations have seriously pushed diesel fuel systems into the spotlight for system maintenance. All diesel is to be used in non-road diesel engines have to be ultra-low sulfur diesel. While being necessary and effective for reducing the amount of unhealthy emissions into the environment, it does pose some problems for facility managers who are in charge of the preventive maintenance routines for any diesel-engine-based emergency power units. Fuel plays a crucial part, and yet it is the least maintained in most aspects. Read on to learn all about ultra-low sulfur diesel and how to use it!

What Exactly is Ultra Low Sulfur Diesel?

Ultra-low sulfur diesel is diesel fuel with lowered sulfur content. Almost all petroleum-based diesel available in the North America and Europe has been a type of ULSD fuel. Although it is cleaner burning and produces less emissions that are harmful, it does have some drawbacks. A much more stringent type of refining process is used, including catalytic cracking along with hydrodesulfurization, destabilizing the fuel and adding the requirement for closer monitoring of fuel tanks and their conditions.


Almost immediately after leaving your refinery, diesel fuel undergoes a lot of chemical changes. The possibility for fuel to generate varnishes and gums will increase over time, typically six months before it starts to produce solids and particulate that can attract other contaminants like dirt and rust. These could clog fuel filters and lead to a total engine shutdown.


Since the refining process removes a few of the fuel’s natural lubricity, it will mix very well with water and is frequently acquired from condensation and leaky storage tanks. This might lead to some issues including corrosion of the storage tank and fuel lines along with increased microbial growth.
