Cardlock Fueling Stations

Renewable Energy Group fuels have always been available from distributors and at terminals, truck stops and convenience stores nationwide. Now, fleets can also enjoy the convenience of filling up with our clean fuels, diesel exhaust fluid (DEF) and other products at cardlock locations in California and Illinois.

Low-Carbon Fuel in California

REG has partnered with cardlock fuel sites in Northern and Southern California to give fleets additional opportunities to fill up with REG Ultra Clean®. REG Ultra Clean is our innovative blend of biodiesel and renewable diesel, creating one of the lowest-carbon liquid fuels available and a great solution for California’s Low Carbon Fuel Standard (LCFS) and the growing number of private sector sustainability plans calling for reduced greenhouse gas emissions.

REG Ultra Clean is available at 18 Hunt & Sons, Inc. cardlock sites in Northern California. Hunt & Sons is a leading fuel distributor in the state and has been in business for 75 years. Customers with a Hunt & Sons purchasing account can buy fuel at more than 236,000 locations across the U.S. and Canada, bringing added convenience and helping to manage fuel costs.

This high-performing, low-carbon fuel is also available through Bains Hwy 99 in Yuba City and, in the Los Angeles metro, at the Cosby Oil cardlock in Santa Fe Springs.

Illinois Cardlock Fuel

We also operate our own cardlock at 610 E. Shipyard Road in Seneca, Illinois, offering 24/7 access to biodiesel blended fuel and DEF to truck fleets and local consumers.

The Seneca Diesel Fueling Station is adjacent to one of our biorefineries and a short drive off Interstate 80. Fleet cards and credit cards are accepted. There is a master dispenser and secondary dispenser, making it easy for trucks to fill tanks on both sides, and plenty of turnaround space.
