What Is Driving Diesel Fuel (Farm) Prices in 2026

Driver	Impact
Crude oil prices	WTI crude is the primary cost driver; farm diesel tracks crude with a 6–8 week lag.
Refinery capacity	U.S. refinery utilization affects the diesel crack spread independent of crude prices.
Seasonal demand	Spring planting and fall harvest create regional price spikes of 5–10 cents per gallon.
Off-road vs. on-road	Dyed off-road diesel runs $0.10–$0.20/gallon below on-road retail; use where legal.

How to Buy Diesel Fuel (Farm) in Indiana

Indiana farmers typically source Diesel Fuel (Farm) through regional co-operatives, independent retailers, and direct distributor contracts. The most effective strategy in Corn Belt markets is to compare co-op pre-pay pricing versus spot retail, as pre-pay discounts of 5–12% are standard for early fall bookings.

• Request competing quotes from at least two distributors before booking
• Ask specifically about pre-pay versus price-later contracts — each has different risk profiles in a volatile market
• Lock in logistics (delivery date, equipment availability) at the same time as price — logistics failures at peak season are as costly as price spikes
• Track NOLA barge prices weekly (GrainBrief does this automatically) to know when your local premium is wider than normal
