Samsara's fleet index shows average US diesel fell 2.9% to $5.15 per gallon for April 20-26. California prices jumped 27.3% in one week to $6.56, driven by West Coast refinery outages and California fuel blend requirements.
Regional refinery outages and tight distillate inventories keep West Coast transport costs high. This raises freight costs for Pacific-facing feed and grain movements even as national prices ease.
After 113 past bullish logistics events, ULSD / Diesel moved a median +0.6% over 5 sessions (54% higher; middle half -2.8% to +4.2%), and +0.2% over 20.
