How Citgo fuel pricing works
Citgo Petroleum Corporation operates three US refineries (Lake Charles, Louisiana; Corpus Christi, Texas; Lemont, Illinois) and supplies fuel to more than 4,200 Citgo-branded retail outlets across the US. Most are independently owned and operated, with Citgo supplying fuel and licensing the brand. Pricing at each station reflects the local wholesale rack price, state and local taxes, and competitive positioning. Citgo corporate does not set retail prices directly.
Citgo ownership history and current sale
Citgo traces its history to 1910 with the founding of Cities Service Company, eventually renamed Citgo in 1965. Venezuela's state oil company PDVSA acquired a 50 percent stake in Citgo in 1986 and the remaining 50 percent in 1990, making Citgo a wholly owned PDVSA subsidiary. Following US sanctions on the Venezuelan government in 2019, PDVSA was effectively cut off from receiving any economic benefit from Citgo, though it remained the corporate parent. In 2025, a federal court in Delaware approved the sale of PDVSA's shares in PDV Holding (Citgo's immediate parent) to satisfy creditor claims, with Amber Energy (an Elliott Investment Management affiliate) selected as the winning bidder at $5.9 billion. As of early 2026, the transaction remains subject to OFAC and other regulatory approvals, and the ownership transfer has not yet been completed.
Top Tier status and fuel quality
Citgo is on the Top Tier Detergent Gasoline brands list, having been added in the 2026 reverify cycle. Top Tier is a fuel-quality standard endorsed by major automakers (BMW, GM, Toyota, Honda, Ford, Audi, Volkswagen, Mercedes-Benz, and others) that requires detergent additive levels above EPA minimums. All Citgo-branded gasoline grades meet the Top Tier specification.
How Citgo compares to other national brands
Citgo's fuel quality (Top Tier) is competitive with Shell, Exxon, Mobil, Chevron, Marathon, Phillips 66, and Valero. Pricing is typically near regional retail averages. The brand's distinctive feature is its complex corporate ownership situation, which doesn't affect station-level operations or fuel quality but is a meaningful public-record context worth being aware of. The pending sale to Amber Energy, if completed, will transition Citgo to US private-equity ownership and remove the Venezuelan-state ownership association.
