The October 27 Energy Information Administration survey puts U.S. regular gasoline at $4.269 a gallon for October 26, down 1.5 cents from October 19. That national dip does not describe every state. Colorado regular rose 18.4 cents on the week, to $4.458, and Ohio rose 33.1 cents, to $4.380. The Midwest regional average also rose 12.4 cents, to $4.269. U.S. on-highway diesel moved the other way from gasoline: it rose 7.6 cents, to $6.352 a gallon. The EIA table does not give a cause for the split. A driver in Colorado or Ohio can pay more this week even while the U.S. gasoline average edges down, and a higher diesel price can raise trucking costs without appearing in the gasoline average.

Could this week's national gasoline dip lower a Colorado or Ohio fill-up? No. EIA shows Colorado regular up 18.4 cents to $4.458 and Ohio up 33.1 cents to $4.380 for October 26, while the U.S. average fell 1.5 cents to $4.269.
