GLACIER NATIONAL PARK, MT

Located in northern Montana, Glacier National Park is one of the coldest spots in the nation.  Since 2001, the park has successfully used B20 year-round in more than 60 diesel vehicles. 

“We’ve had no issues related to performance or reliability,” said Lou Summerfield, who served as the park’s fleet manager until 2006.  “We use B20 in dangerous conditions
tolerance for failure.” 

B20 is used in vehicles ranging from 1983 to 2004 models including Cat, Detroit, Powerstroke, Cummins, Duramax and stationery generators.
