"Some areas are experiencing temporary fuel outages. Our locations across the southeast may have been impacted by this issue," according to a spokesperson for Racetrac Petroleum, the fourth largest gas stations operator in the United States.
The Racetrac Petroleum spokesperson said they are working around the clock to provide uninterrupted fuel supply.
"We continue to closely monitor the situation with Colonial Pipeline to help us understand any potential impacts to service," a BP spokesperson said.
A spokesperson for Shell also said that the company is actively engaged with Colonial Pipeline to understand steps they are taking to resolve the issue.
"Nothing I can add on specific impacts to product flow," he said.
"We are leveraging our logistics network and commercial relationships as we work to keep our customer supplied with fuel," he said.
The Colonial Pipeline, which delivers about 45 percent of the fuel consumed on the US East Coast, was hit by a cyberattack on Friday. As the shutdown entered its sixth day, US media reported that fuel pumps in the East Coast were running out of fuel and there were long lines of cars waiting to fill up. The average price of gasoline has also soared on the disruption to a seven-year high that was just short of $3 per gallon.
