Seasonal Diesel: Is it really a thing?

Jan 31, 2025 | 3:04 PM

It actually is, let’s break it down.

Co-op® Premium Diesel is a seasonally adjusted diesel fuel blend that’s designed to perform well in cold weather. While other fuel providers have moved to a single diesel blend that’s available year-round, Co-op is proud to continue offering winter and summer blends of Co-op® Premium Diesel. It is worth noting that Co-op is the only diesel supplier that can provide the full summer diesel product during this time of year, other suppliers offer a blended product which will not provide the same power and efficiency as Co-op Premium Summer Diesel.

The Co-op Refinery Complex (CRC), located in Regina, Sask., adjusts fuel blends regularly, sometimes 10-12 times a year. However, the primary switch of diesel blends happens twice per year in preparation for summer and winter weather. With the harsh winter temperatures experienced in Canada, diesel can gel up, which leads to long-term wear on equipment and reduced fuel efficiency. The lighter components in winter diesel blends keep viscosity problems at bay.

How it works

  • Lubricity additives: Reduce wear on the engine and fuel system
  • Cloud and pour point adjustments: Prevent wax and crystallization from forming in the fuel
  • De-icers: Protect the system and improve performance at sub-zero temperatures
  • Cold flow improvers (CFIs): Dissolve paraffin wax bonds so it can pass through the filter

Benefits

  • Improved performance: Co-op® Premium Winter Diesel can help your engine run more efficiently and powerfully
  • Reduced wear: it can help protect your engine and fuel system from wear and tear
  • Longer fuel filter and pump life: can help extend the life of your fuel filter and pump
  • Improved corrosion protection: Co-op® Premium Winter Diesel can help protect your engine from corrosion

Winter Diesel Blends: What’s Different?

  • Cloud Point is adapted to increase flow capability. This specification measures the temperature at which crystal formation starts in diesel fuel, an indication of the operability in low temperatures.
  • Pour Point, another important diesel specification, is altered to reduce fuel viscosity, which often occurs when the temperature changes, increasing overall fuel performance.
  • De-icers protect system integrity and offer improved performance at sub-zero temperatures.
  • Enhanced lubricity additives reduce engine and fuel system wear.
