For drivers in need of diesel exhaust fluid (DEF), Yara International has a solution. The new Air1 DEF Mobile Locator uses GPS to identify the nearest DEF retail outlets to a driver's location.
The app is available for free from the iTunes app store for the iPhone, iTouch, and iPad. An app for Android devices will be released this month and a Windows 7 version in September.
Yara is a global producer of DEF.
