Gas prices in Door County reached $4.23 per gallon this week. The cost of fuel in the region jumped by more than 25 cents compared to the previous week. Brown County recorded a price of $4.17 per gallon. Fond du Lac County remained the most affordable area at $3.91 per gallon. Diesel prices in Wisconsin reached a record high of $6.11 per gallon.

GN auto markets/energy: gasoline prices reported these sharp increases across northeast Wisconsin. The data indicates a significant spike in retail fuel costs. The upward trend is not limited to a single county. Multiple locations in the region experienced similar price hikes this week.

Supply Chain Disruptions Drive Costs

Patrick De Haan of GasBuddy identified multiple concurrent supply issues. Continued escalations in the Middle East contribute to global price pressure. Ukrainian drone attacks on Russian refineries further reduce available supply. A refinery near Chicago lost power for several hours over the weekend. This outage added strain to Midwest fuel distribution networks.

No Immediate Price Relief Foreseen

De Haan stated that no clear turnaround is visible on the horizon. He described the situation as requiring diplomatic de-escalation rather than a simple calendar date. The full impact of current disruptions may not yet be reflected in pump prices. Fuel costs could rise by another 20 to 40 cents in the coming days.

Regional Price Variations Persist

Price differences remain noticeable across county lines. Door County remains the most expensive area in the tracked region. Fond du Lac County offers the lowest rates for regular unleaded gasoline. The spread between the highest and lowest prices is 32 cents per gallon. These local variations reflect different supply chain pressures and retailer strategies.
