This article discusses the importance of modern low sulfur diesel fuels, such as EN590 and BS2869, conforming to specific standards for Filter Blocking Tendency (FBT).

The article explores common causes of FBT failures, the role of particulate contamination, and the benefits of using additives like Aquasolve to improve fuel quality, reduce emissions, and prevent engine damage.
