WINTER FUEL PROGRAM

2023-2024 Winter Fuel Program

With winter approaching, we wanted to take this opportunity to notify you of our program for this upcoming season. For less than truckload deliveries (above ground tanks and direct to unit fueling), we will cease Biodiesel blending and begin our winter additive blending process for all Diesel Fuel on November 6th. We will be distributing #2 Ultra-Low Sulfur Diesel with Winter Additive until Spring 2024. In the anticipated occurrences that temperatures will reach the single-digit and sub-zero range for an extended period, it is Al Warren Oil Company, Inc.’s intent (based on product availability) to implement the following blending procedure of #2 Ultra-Low Sulfur Diesel and #1 Ultra-Low Sulfur Diesel including winter additive.

WHY IS DIESEL IMPACTED BY LOW TEMPERATURES?

Diesel fuel contains paraffins, which means that at low temperatures, the wax precipitates, or separates, from the fuel as wax crystals. As the temperature falls, these crystals grow and cover the fuel filter surface, which can lead to fuel starvation, loss of engine power and eventually stalling. Wax plays an important role in the fuel by enhancing cetane, which improves cold starting.

WHAT IS A COLD-FLOW IMPROVER?

Cold-flow improvers are used to modify the shape of the wax crystals so that fuel keeps flowing through fuel filters at lower temperatures. Since the weather is not always predictable, a cold-flow improver provides an added margin of safety for cold-weather operability. #1 Diesel fuel blending is an option for severe cold weather treatment.

WINTER DEF PREP TIPS FROM AL WARREN OIL

STORAGE CONSIDERATIONS

  • DEF can expand by up to 7% when frozen. Therefore, it’s vital to keep storage tanks less than full to avoid damaging them.
  • Al Warren Oil’s Expert Advice: Invest in DEF-specific, insulated bulk storage tanks. If you’re thinking about storing multiple products in the same tank, think again. These tanks should only be used for DEF and must be thoroughly rinsed with either distilled or de-ionized water, or on-spec DEF before switching contents.
STORAGE CONSIDERATIONS

IN-VEHICLE DEF HANDLING

  • Frozen DEF won’t hinder your vehicle from starting; most modern SCR (Selective Catalytic Reduction) systems include a heating element that will quickly thaw the DEF.
  • Al Warren Oil’s Recommendation: Absolutely avoid adding any substances to thaw DEF in the vehicle. Purity is critical for DEF to function correctly in reducing harmful emissions.

TRANSFER & DISPENSING

  • A closed-loop system is the most reliable way to transfer DEF from drums or bulk tanks. This system prevents external contaminants like dirt and dust from getting into the fluid.
  • Al Warren Oil’s Best Practice: Use dedicated pumps, hoses, and nozzles solely for DEF dispensing. This minimizes the risk of contamination and ensures the DEF meets ISO 22241 standards.

CLEANING & MAINTENANCE

  • Cleaning tools used for DEF should be rinsed with distilled or de-ionized water. Follow up with a DEF rinse to ensure zero contaminants.
  • Al Warren Oil’s Tip: Never use tap water for cleaning; it can introduce minerals that compromise DEF quality.
