Beyond Lubrication: How Caltex Marine Oils Keep the Marine Industry Ready for What’s Next
In the marine industry, lubricants do far more than keep metal parts moving. They sit at the heart of every ship’s reliability, efficiency, and compliance strategy — silently protecting engines, thrusters, cranes, compressors, and countless other systems that power global trade.
But today, running a vessel isn’t just about mechanical protection. Operators face tighter environmental regulations, unpredictable fuel quality, rising costs, and the growing demand for sustainability. That’s why Caltex Marine lubricants aren’t designed simply to “meet specifications” — they’re engineered to help fleets stay competitive in a world that’s constantly evolving.
From high-performance engine oils built for modern slow steaming conditions, to hydraulic fluids, gear oils, environmentally acceptable lubricants (EALs), coolants, greases and beyond — Caltex offers a complete portfolio that does more than protect equipment: it keeps ships efficient, compliant and ready for what’s next.
In this article, we explore the types of Caltex Marine lubricants, where they’re used on board, and — more importantly — why they matter to the real-world challenges of today’s marine operations.
Types of Caltex Marine Lubricants
Caltex offers a broad portfolio designed to meet the diverse demands of modern fleets:
Engine oils – Caltex offers a range of slow-speed two-stroke and medium-speed four-stroke cylinder and diesel engine oils. Brands in this range are Taro and Delo.
Coolants – Caltex also offers diesel engine coolants like the Delo XLI Corrosion Inhibitor – concentrate cooling water treatment that helps provide maximum protection and lasts longer than many traditional technologies in marine systems keeping marine engines running for longer. It is also 92% degradable, saves time and money due to extended service intervals of 32,000 hours and also helps minimize maintenance costs by reducing wear.
Hydraulic oils - Caltex’s range of hydraulic turbine oils are designed for wide- range operating temperature, are inherently biodegradable and help prevent corrosive wear to help optimize productivity and equipment uptime.
Compressor oils – Caltex’s range of compressor oils are formulated with VARTECH technology and help reduce varnish formation, inhibit corrosion and provide excellent operational reliability through oxidation and thermal stability with long service life.
Gear oils – Caltex’s range of gear oils like Meropa contain special additives that are designed to provide gear cleaner, better for extreme temperature protection and anti-wear properties for reliable performance in wet conditions and high operating temperatures.
Turbine oils – Caltex’s range of GST turbine oils protect gear sets, resist the formation of harmful deposits and aid potential maintenance and downtime savings due to oxidant inhibition and good water separability.
Greases & Open Gear lubricants – Caltex’s greases and open gear lubricants aid component protection, good corrosion protection in wet environments and perform over a long service life in load carrying applications.
Benefits of Caltex Marine Products
Caltex Marine Lubricants deliver tangible operational and commercial benefits:
Reliability & Efficiency - Advanced formulations help prevent deposits, varnish, and wear — keeping fleets running longer between overhauls and reducing unplanned downtime.
