How Can I Prevent Diesel Fuel from Gelling in Cold Weather?
When the temperatures drop, diesel fuel gelling becomes a critical issue for diesel generators and vehicles. Gelling can cause operational downtime, increased maintenance costs, and, in severe cases, damage to your equipment. This guide offers practical tips and proven strategies to help you prevent diesel fuel from gelling during cold weather. What Is Diesel Fuel Gelling? Diesel fuel gelling occurs when paraffin waxes in the fuel solidify at low temperatures, forming crystals that clog fuel lines and filters. The process begins at the cloud point, the temperature at which wax crystals become visible, and worsens as temperatures drop toward the pour point, where the fuel stops flowing entirely. Understanding these properties is key to preventing gelling and ensuring the reliability of your diesel generator or vehicle in winter conditions. Why Does Diesel Fuel Gel in Cold Weather? The primary reason diesel fuel gels is its high paraffin content, which provides excellent lubrication b
