HI-99 is giving you the chance to win tickets to the 4 Wheel Jamboree Nationals on September 19th-21st at the Indianapolis Fairgrounds!

You just have to "Ask the Diesel Diva" a question!


The HI-99 Donut Patrol wants to bring donuts and coffee to your business. Every Tuesday, the Waking Crew draws the winning office and we deliver the donuts on Thursday morning, courtesy of Baesler’s Market.
