Chicago-area truckers will be able to fill their diesel exhaust fluid (DEF) tanks at Mid-Town Petroleum, which will distribute DEF as a member of Mansfield Oil’s DeliveryOne network of suppliers.

Mid-Town will distribute Air1 DEF for Chicago, northern Illinois, northwest Indiana and southern Wisconsin.

“There’s been a lot of hype in the trucking and heavy duty industry communities about diesel exhaust fluid,” says Randy Weiss, vp of sales for Mid-Town. “My goal in the next year is to take the time to educate our customers about how to safely integrate DEF into their operations.”
