You knew it was too good to last. Gas prices are expected to rise sharply in the next few days after a Midwest refinery ran into problems.

Patrick DeHaan is a Senior Petroleum Analyst from the gas watchdog website He says a problem arose in Indiana...

"....the region's largest refinery, the BP Refinery in Whiting, Indiana went down unexpectedly on Saturday, one of its largest units shut down. That unit close to half the capacity of that refinery. It may be shut down for a week or two....."

An industry analyst says the petroleum market threw a "temper tantrum" last week, and as a result summer time gas prices went up sharply.

While prices are prone to rise during the summer travel season, Patrick DeHaan from the website reports a federal report sparked a furor...

"....prices really accelerated late last week. That was after the government's weekly report came out Wednesday highlighting a large decrease in crude oil inventories...."

Like the thermometer that rises each summer, gas prices are starting to head upward after being near $2.00 a gallon this past winter.

Senior Petroleum Analyst for the website  Patrick DeHaan,  says refinery problems helped trigger high prices....

"....Exxon-Mobil's Joliet refinery suffering from undisclosed issues and that caused wholesale prices to go up. We've also seen the price of crude oil bumping back up close to 2015 highs and that's influencing gas prices as well...."

The pleasure of $2.00 a gallon gasoline has left and an energy specialist thinks prices will be going up sharply in the next few days.

Wisconsin's price is at $2.29 up about two cents from last week, and with wholesale prices going up, prices are expected to go up at least another nickel in the next week.

Patrick DeHaan from the website gasbuddy. com says even though there's plenty of oil in the U.S., refineries are providing a type of bottleneck...

The recent spike in gas prices is not only because prices rise for summer travel but because of the turbulent situation in the key oil-producing nation of Iraq.
That's the assessment of a senior petroleum analyst for the website...gas buddy dot com Greg Laskoski...

"....we're at $3.74 right now, a week ago they were at $3.72. A month ago it was $3.59. So there's no doubt we're seeing increases. This is all across the Great Lakes region and certainly across the rest of the country as well...."

Corn is likely one  reason why gas prices have inched up lately, but there is another reason.

A petroleum analyst for the website gas buddy dot com says gas refiners are still in the process of shifting over to summer blend gasoline  so states can meet federal air quality rules.

What day of the week do you think has the highest prices? What day has the lowest?

The website took four years of data and guess what part of the week has the lowest prices....


".....we tend to find Friday, Saturday, Sunday, Monday were the best four days over the last four years with the exact day switching from year-to-year...."


That's Senior Petroleum Analyst Patrick DeHaan. He says Tuesday and Wednesday appear to be the days where prices rise.

Just before Christmas, gas prices took a jump after falling to about $3.11.  

Patrick DeHaan, a petroleum analyst for the website Gas told Ken Krall this likely is a short-term rise.

DeHaan says another factor in rising gas prices, tension in the oil-producting Middle East, is beginning to lessen. He says that factor also is stabilizing prices.

Holiday gas prices are expected to be stable but longer term they are likely to rise again, according to a petroleum analyst for the website gas buddy dot com

Prices have been declining since summer, with some stations in Milwaukee below $3.00 a gallon.

Patrick DeHaan says as the weather gets colder people don't drive as much...

Gas prices had dropped to $3.31 per gallon this week, then Wednesday the price rapidly spiked to $3.49 per gallon in Rhinelander and Eagle River, $3.39 in Minocqua, but held at $3.30 in Antigo, according to the website gasbuddy. com  Senior Petroleum Analyst Gregg Laskoski says wholesale prices are to blame for the spike after a long downward trend...
