It is that time of year again. Cold mornings, frosted windows, and chilly winds, which means it is time to winterize your stored diesel fuel. If No. 2 diesel starts to cool during freezing, overnight temperatures, it could reach “cloud point,” when wax crystals start to develop in the fuel. The fuel will start to look cloudy, and crystals can plug up the fuel filter, which results in poor starts, engine hesitation, stalling, and engine damage too. Use the following guidelines to help winterize fuel that is leftover from harvest to avoid any issues.
Knowing When to Blend
The cloud point for diesel is approximately 14 degrees Fahrenheit. A solid rule of thumb is to switch a winter blend around 15 degrees above the cloud point. When overnight temperatures start to dip down around 30 degrees, it is time to blend in your top diesel with some additives for the winter. For every 10 percent of top diesel that is added, the fuel cloud point drops by about three degrees. Do not let the cloud print surprise you since crystals can quickly build up in the fuel during a cold snap, but they might still run just fine. Even if the fuel is properly blended after reaching cloud point, these crystals can remain and clog up equipment. An engine that runs nicely on a cold day could leave you stranded a few days after. For this reason, an early-season switch to winter-grade fuel is highly recommended.
Factor in Your Remaining Inventory
While blending fuel, do not just pour No 1. diesel on top of your stored fuel. First, gauge your remaining inventory, or the total volume of No. 2 left in your tank, before you start blending any winterized fuel, and then reach the correct blend before bringing in the first delivery of a winterized product. If No. 1 diesel is added to your storage tank without correct blending, the winterized product could be diluted, negatively impacting the fuel quality.
