Fine Print
- Gas/Diesel: EIA weekly survey (Mondays). Illinois line from AAA state average.
- Retail propane & kerosene-adjacent heating oil: EIA weekly, collected Oct–Mar only — off-season shows the last reading.
- Mont Belvieu propane is a hub spot price (ref-level), shown for reference, not pump price.
- SPR inventory is no longer published on any public feed (DOE posts only press releases); we chart EIA commercial crude stocks instead.
- Updates daily ~9:00 AM CDT. Local station prices are crowd-sourced; call before driving.
