Citgo Engine Oil

About CITGO Petroleum Corporation

Few names in American energy carry the depth of history and expertise that CITGO Petroleum Corporation does. The company's roots trace back to 1910, when oil pioneer Henry L. Doherty founded the Cities Service Company — a venture that would help shape the modern petroleum industry in the United States. CITGO as a brand was introduced in 1965, with the name chosen to carry the spirit of forward momentum: the "GO" suffix was intentional, evoking power, energy, and progress. The iconic CITGO "trimark" logo followed shortly after and remains one of the most recognizable symbols in American energy.

Formally incorporated in 1983, CITGO today is headquartered in Houston, Texas — the heart of the U.S. energy industry. The company has grown into one of the most complex independent petroleum refiners in the country, operating three major refineries and multiple lubricants blending and packaging plants. Its reach extends across thousands of locally owned retail outlets, all located east of the Rocky Mountains, making CITGO a trusted name from the Gulf Coast to the Great Lakes.

What CITGO Makes

CITGO is fundamentally a refiner, transporter, and marketer of petroleum-based products. Its portfolio spans transportation fuels, petrochemicals, and — critically for vehicle and equipment owners — a full line of lubricants. These include industrial-grade greases and motor oils engineered to meet the demands of modern engines and heavy machinery. CITGO's lubricant production is backed by dedicated blending and packaging facilities, ensuring consistent quality across every product it brings to market.

For those maintaining vehicles, fleets, or mechanical equipment, CITGO's lubricant lineup offers practical solutions built on over a century of petroleum science. Whether you need a reliable multi-purpose grease to protect bearings and joints under heavy load, or a quality engine oil to keep a motor running at its best, CITGO draws on deep refining expertise to deliver formulations that hold up under real-world conditions.

CITGO Lubricants for Vehicles & Equipment

CITGO's Multi Purpose Grease products are a natural extension of the company's century-long heritage in petroleum refining. Designed to protect metal surfaces under pressure, these greases are commonly used in automotive, industrial, and agricultural applications — anywhere that friction reduction and corrosion protection are essential. CITGO brings the same refinery-level quality control to its greases that it applies to its fuels, making them a dependable choice for both professionals and everyday users.

Complementing the grease lineup, CITGO Engine Oil reflects the brand's commitment to keeping engines running cleanly and efficiently. Drawing on decades of lubricant formulation experience, CITGO engine oils are engineered to meet the viscosity and performance standards that modern gasoline and diesel engines require. For drivers who trust the CITGO name at the pump, their engine oil offerings bring that same level of petroleum expertise directly into the crankcase.

A Legacy Built on Reliability

What distinguishes CITGO in the lubricants market is not just product breadth, but institutional knowledge. With three lubricants blending and packaging plants, a vast distribution network, and more than a century of hands-on petroleum refining experience, CITGO has the infrastructure and expertise to back every product it puts its name on. For mechanics, fleet managers, and DIY enthusiasts alike, that pedigree matters when selecting oils and greases for critical applications.
