Why Diesel Costs $5.47/Gal in Michigan
Michigan diesel ($5.26/gal) reflects Midwest pricing with a moderate state tax of 26.3 cents/gal. Detroit-area diesel demand is driven by the automotive manufacturing industry - auto parts plants, assembly plants, and related logistics create intensive Class 8 and medium-duty diesel demand. Michigan also sees seasonal pricing pressure from home heating oil demand (chemically equivalent to diesel) in winter. The I-75 and I-94 corridors are major truck routes.
