The Weekly Fill-Up | February 9-13

February 9, 2026

As we move deeper into February, winter conditions across eastern South Dakota continue to demand steady attention to fuel and propane planning. While the calendar may be inching toward spring, fuel usage patterns and heating demand remain firmly in winter mode. For Sioux Valley Coop members, this week is about staying consistent and avoiding mid-winter complacency.

Diesel fuel prices have shown little movement in recent weeks, maintaining a stable pattern through early February. Although pricing remains above last year’s levels, the absence of volatility suggests the market is holding steady. For daily operations that rely on diesel — including trucks, loaders, generators, and livestock equipment — stability is helpful, but it does not eliminate risk. Winter storms and cold snaps can still impact delivery timing, making it important to keep bulk tanks adequately filled rather than waiting until levels run low.

Fuel usage often remains higher than expected during this part of winter. Even without heavy field activity, extended idle times, cold starts, snow removal, and daily livestock care continue to draw steadily from diesel supplies. Reviewing recent consumption trends can help determine whether delivery frequency should be adjusted as winter conditions persist.

Propane demand remains strong as heating needs continue across rural homes, shops, and livestock facilities. National propane inventories entered winter at solid levels, supporting relatively stable pricing throughout the season so far. However, local usage can rise quickly during prolonged cold stretches. When temperatures remain low for several consecutive days, delivery schedules tighten and flexibility decreases. Monitoring tank levels regularly and scheduling fills before tanks approach minimum thresholds helps prevent avoidable disruptions.

The week of February 9 also serves as a reminder that winter often lingers longer than expected. Late February and early March can still bring harsh conditions. Using this time to confirm tank capacity, review delivery timing, and communicate anticipated needs with Sioux Valley Coop ensures smoother service during the remaining weeks of winter.

Overall, the message this week is steady and proactive. Fuel and propane markets are stable, but winter logistics still require careful planning. Staying ahead of tank levels, anticipating usage, and scheduling deliveries early remain the most dependable ways for Sioux Valley Coop members to keep operations running smoothly through late winter.
