Motorists who drive fuel-efficient vehicles had good reason to pat themselves on the back the past few days as gasoline prices spiked to record levels in the Midwest.

In Madison, a gallon of gas last week cost $4.25. This morning prices ranged from $3.95 to $3.98 at Madison service stations. What the price will be tomorrow is anyone's guess.

Hoosiers are fighting mad and they're venting to Attorney General Greg Zoeller's office.

The state agency said Friday that it has received 80 complaints about high gas prices so far this month, up from just 15 last month.

Indiana's average price for a gallon of regular unleaded was $4.12, behind Hawaii, Michigan and Illinois, and about 50 cents higher than the national average, the office said Friday.

In comparison, Indiana's average price of a gallon of regular unleaded was $3.59 between Jan. 1 and June 1, it said.

Tom Bodin, the office's chief economist, said he's determined that Indiana's recent spike in gas prices is being fueled by production delays at seven of the Midwest's 10 largest refineries.

The seven refineries that have been either hit by technical problems or are conducting maintenance include the top three Midwestern refineries by output volume.

The AG's office is satisfied that the latest spike does not involve price-gouging. Supply and demand is so delicately balanced that any disruption is quickly felt.

Typically when prices spike people look for someone to blame.

Last week was no exception.

But, Americans still are not doing enough to cut their gasoline consumption.

When it actually comes to doing something about high gas prices, the best advice still is to leave the car parked when walking will do and to choose wisely when buying your next vehicle.
