Saudi Aramco used to be a big supplier of not only crude oil, but also of Diesel fuel. Statistics show that as of the summer of 2025 (before the war), the company sold on average 255,000 barrels of diesel fuel per day. That’s 10,710,000 gallons per day.
And as of right now, not only are they not selling a single barrel of diesel, they are actually in the market buying diesel.
