Stillwater-based fuel retailer OnCue Express celebrated a milestone Thursday.
OnCue Express has sold 3 million gallons of compressed natural gas since it started offering the gasoline alternative in 2009.
"This is the most of any Oklahoma private-sector retailer and a national milestone," CEO Jim Griffith said at the OnCue station at 1 NW 23rd in Oklahoma City.
Governor Mary Fallin said the milestone is great news for OnCue and Oklahoma.
"OnCue, in my opinion, is a national leader," she said, praising the company for investing in CNG fueling infrastructure.
