The price of propane in Minnesota is well below the high cost of gasoline and diesel fuel.   More drivers are making the switch or converting their vehicles to propane autogas.  Dave Wager of the Minnesota Propane Association says you can fill up at several locations including their facility in Zimmerman:

“We have a dispenser. You put your credit card in it, you have a vehicle that runs on propane , you can dispense it in your vehicle,  fill it and drive away.  The pump looks the same. Right now we’re at two-34-9 per gallon and it appears the average price in the Midwest is two-37 a gallon.”

Wager says propane conversion kits are several thousand dollars, but the association offers incentives to help to cover a large chunk of the cost.   You can also buy dedicated vehicles and buses powered by propane.
