For Immediate Release

RADCLIFFE, Iowa/EWORLDWIRE/June 26, 2008 --- Mirenco Inc. (OTCBB: MREO) announces that numerous large national aggregate and coal mining companies have accepted Mirenco's fuel saving technology as a solution for reducing their vehicle operation costs.

The driving force behind this acceptance is the use of Mirenco's products and services that Whayne Supply ('http://www.whayne.com') provides to these customers who are operating within the current market of record high diesel fuel prices. These large coal and aggregate mining companies have saved thousands of gallons of diesel fuel after Whayne Supply technicians, using Mirenco's combustion management technology, have tuned their giant industrial engines for peak combustion efficiency. Currently, Whayne Supply, a Caterpillar distributorship, markets these products and services in Kentucky and southern Indiana.

"By comparing the first quarter of 2007 to the first quarter of 2008 in our SEC filings, you can see the improvement in Mirenco's bottom line. This is due to the increasing fuel prices and our new business relationship with Whayne Supply," says Dwayne Fosseen, Mirenco's chief executive officer.
