Gas prices in San Luis Obispo County have increased by 6 cents per gallon over the past week, reaching an average of $4.77. This rise is attributed in part to Valero's announcement that it will be closing its refinery in Benicia, which produces about 12% of California's gasoline. The average price across the state has also gone up by 3 cents to $4.61, while the national average increased by 1 cent to $2.93. However, some gas stations in SLO County are offering lower prices, with the top 10 cheapest locations ranging from $3.97 to $4.37 per gallon.

Why it matters

This comes at a time when many are already struggling with the economic impacts of the pandemic, making affordable fuel an important issue for local communities.
