Peter Afunanya, who is a spokesman for the Service, said this at a press conference on Thursday in Abuja.
He said that SSS had a meeting behind closed doors with the relevant oil industry groups, and they all agreed to end the shortage.
"Today, we met with NNPLC and other stakeholders in the downstream sector, such as the Nigerian Midstream and Downstream Petroleum Regulatory Authority, the Nigerian Union of Petroleum and Natural Gas Workers, the Independent Petroleum Marketers Association of Nigeria, the Major Oil Marketers Association of Nigeria, and depot operators, among others," Mr. Afunanya said.
"We were clear and told them that the lack of fuel was getting old. We told them they should get rid of the problems as soon as possible. Nigerians should be able to get their hands on oil products. We told them we wouldn't put up with the lack of food any longer."
People might wonder why the SSS stepped in, the spokesperson said. He said that the Service is required by the Constitution to find and stop threats to internal security, which the continued lack of food could become.
He said, "You might wonder what we have to do with this. Don't forget that the Constitution gave us the job of finding and stopping any threat to our security from happening.
"We also have the right to look into economic sabotage that threatens national security.
"The most important thing we learned from our discussion is that there is enough fuel in the country to last us through the holiday season and beyond.
"The NNPCL said that there are 1.9 billion barrels of oil in stock, and everyone involved agreed with that number.
"At the end of the meeting, one of the decisions made was that the marketers will work every day for 24 hours.
"Also, the people who run the tankers promised that everyone would help lift the goods.
"In the same way, the NNPCL agreed to sell at the price "ex-depot." It also agreed to make distributions less centralised, which would be good for marketers.
He said that the Service had promised to provide security to make sure that fuel kept getting to all parts of the country.
"For our part, we agreed to make sure the products got to all parts of the country without any problems. Distribution must get better and all problems must be solved in the next 48 hours. After that, we'll do operations all over the country as soon as possible, no matter who gets hurt, Mr. Afunanya said.
He said that all SSS commands have been put on red alert and that operations will start to catch people who don't pay their bills.
