In the present-day world, cleaner options for fuel sources have transitioned from being a preference for the environment, to a necessity. Knowing the differences between Ultra Low Sulphur Diesel Fuel (ULSD) and normal diesel is becoming increasingly important as industries and transportation systems shift towards more sustainable fuel sources.
At The Sole Trader, we pride ourselves on supplying premium branded, low emissions diesel fuel solutions to help companies reduce their impact on the environment without any downtime. This article will distinguish what makes Ultra Low Sulphur Diesel Fuel different from regular diesel and the importance of the difference to your operations.
1. What Is Ultra Low Sulphur Diesel Fuel?
Ultra Low Sulphur Diesel Fuel (ULSD) is a cleaner burning diesel containing considerably less sulphur than traditional diesel. Sulphur is a natural derivative of crude oil, and sulphur creates harmful emissions such as sulphur dioxide (SO₂), which leads to acid rain and reduces air quality.
Fuel regulations worldwide now require a radical decrease in sulphur content of fuel for the purpose of protecting our environment. ULSD has no more than 15 parts per million (ppm) of sulphur compared to nearly 500 ppm found in the older normal diesel formulation.

2. Regular Diesel: The Traditional Standard
Prior to the advent of ULSD, regular diesel—sometimes referred to as "Low Sulphur Diesel" or "High Sulphur Diesel" based on the region—was the conventional norm for automobiles and heavy construction equipment.
In many ways regular diesel provided good horsepower, unfortunately, because of the high sulphur content it also caused significantly higher emission of particulate matter, nitrogen oxides, and other pollutants that not only degraded air quality, but also posed a risk to public health. So, regulators worldwide required a cleaner alternative.
In many parts of the world today, on-road use of regular diesel is completely gone; all diesel on-road use consists of Ultra Low Sulphur Diesel fuel compliant with strict regulatory controls.
Key Differences Between Ultra Low Sulphur Diesel and Regular Diesel
Let's take a look at the main differences that are at odds with ULSD and diesel fuels:
Feature Regular Diesel Ultra Low Sulphur Diesel (ULSD)
Sulphur Content Up to 500 ppm or greater Maximum 15 ppm
Emission Output Higher SO₂ and particulate emissions Lower emissions
Engine Compatibility Older engines Newer engine with emissions systems
Environmental Impact Contributes to air pollution and to some degree, water pollution Cleaner and helps to minimize acid rain and smog
Fuel Lubricity Sulphur naturally lubricates Requires lubricity additives
Global Availability Declining rapidly Widely available globally
Feature Regular Diesel Ultra Low Sulphur Diesel (ULSD)
Sulphur Content Up to 500 ppm or greater Maximum 15 ppm
Emission Output Higher SO₂ and particulate emissions Lower emissions
Engine Compatibility Older engines Newer engine with emissions systems
Environmental Impact Contributes to air pollution and to some degree, water pollution Cleaner and helps to minimize acid rain and smog
Fuel Lubricity Sulphur naturally lubricates Requires lubricity additives
Global Availability Declining rapidly Widely available globally
The bottom line? Ultra Low Sulphur Diesel Fuel
4. Why the Transition to Ultra Low Sulphur Diesel Fuel is Important: a. Reduced Air Pollution and Cleaner Air The primary reason for the switch to ULSD is to reduce harmful emissions. Lowering sulphur in diesel will lower sulphur dioxide (SO₂) and particulate matter (PM), which account for a large portion of air pollution and present major health risks. Used in conjunction with newer diesel engines, ULSD reduces nitrogen oxides (NOₓ) and carbon emissions, and will result in both cleaner air in cities and a healthier environment overall.
b. Better Compatibility with Newer Engines Newer diesel engines were designed to maximize efficiency based on lower emission diesel fuel. With the introduction of exhaust after-treatment systems, diesel still combusts in the engine, but additional systems are deployed to further mitigate emissions. Modern after-treatment systems need ULSD to work as expected. A modern engine running regular diesel would likely see issues (clogging) or performance issues, and possibly costly repairs. Using ULSD will equate to better engine performance, better fuel combustion, and longer life of equipment.
c. Compliance with International Regulations Multiple countries, such as the UK, member countries of the EU, the US, and several others have made Ultra Low Sulphur Diesel Fuel (ULSD) a requirement for their on road vehicles. This regulatory requirement means businesses and transport operators are obliged to comply or risk penalties. This is why at The Sole Trader, we ensure compliance is easy with our ULSD offer which is of the highest quality ULSD meeting or exceeding global fuel standards.
5. Clarifying Myths Associated with ULSD
"ULSD Impacts Fuel Economy"
Some operators are concerned that the refining processes associated with the removal of sulphur impacts energy content and would result in decreased fuel efficiency. While this is the case for most fuels, the difference in energy content between regular diesel fuel and ULSD is nominal (often less than one percent).
Modern engines are designed to achieve fuel combustion; therefore, efficiency will be more or less the same as before.
"ULSD Harms Older Engines"
It is true that the removal of sulphur reduces natural lubricity. However, refiners are now adding lubricity enhancers in ULSD to minimize wear on engine parts. Specifically, if you purchase Ultra Low Sulphur Diesel Fuel from a reputable fuel supplier like The Sole Trader, you can trust that this will meet all lubricity performance and protection standards.
