In Puerto Rico, American Petroleum, through its subsidiary Royal Petroleum, supplies Mobil1 brand oils, greases, and lubricants specifically designed for marine applications.
We work with commercial fleets, private vessels, cargo ships, and maritime operations that operate under demanding conditions, where salt spray, constant humidity, and continuous operation are part of daily life.
We focus on ensuring availability when needed and coordinating efficient, reliable deliveries directly to the port, so that maintenance and restocking can be carried out without disrupting schedules.
Mobil1 Oils, Lubricants, and Greases
Our portfolio is geared toward diesel engines and onboard power generation systems, where product consistency and protective capabilities are key to reducing wear and supporting more predictable maintenance schedules.
We provide solutions aligned with manufacturer recommendations, ensuring that each application uses the right product based on its function within the system. These include:
Gear Oils
Onboard gear systems operate under constant loads and require lubrication that maintains system stability and reduces wear.
For these applications, we supply oils from the Mobilgear 600 XP line, used in gearboxes and auxiliary systems where protection against extreme pressure is key.
Available in different viscosities depending on equipment requirements:
- Mobilgear 600 XP 150.
- Mobilgear 600 XP 220.
- Mobilgear 600 XP 460.

Greases
Components exposed on deck require additional protection against moisture, salt spray, and high loads.
For these applications, we supply Mobilgrease XHP™ 222, a lithium complex grease used in bearings, cranes, and winches, designed to resist water washout and protect against corrosion.
Hydraulic Oils
Hydraulic systems on vessels operate continuously and require fluids with operational stability.
We supply the Mobil DTE 10 Excel line, used in deck cranes and hydraulic systems, available in the following viscosities: 15, 32, 46, 68, and 100.
Engine Oils for Onboard Machinery and Systems
Auxiliary engines and power generation systems require constant lubrication under demanding conditions.
For these applications, we offer:
- Mobil Delvac MX F2 15W-40, used in high-speed diesel engines.
- The Mobilgard line, for medium-speed engines, where it is necessary to control deposits, acidity, and water separation.
Mineral oils for circulation systems (Mineral Oils)
In systems where fluid compatibility and stability are key, we supply Mobil DTE Heavy Medium, used in turbines and circulation systems.
This type of oil helps maintain stable operation, controlling oxidation and facilitating water separation within the system.

ExxonMobil Oil Viscosities
In marine applications, viscosity selection depends on the type of equipment and its operating conditions.
At American Petroleum and Royal Petroleum, we work with specifications used in marine systems, ensuring that each product meets the equipment’s technical requirements, such as:
- 5W30.
- 10W40.
- 15W40.
Proper viscosity selection is a key factor in maintaining system stability and preventing operational failures.
Sectors where ExxonMobil products are used
Our focus is on meeting the specific needs of vessels, including:
- Main engines.
- Auxiliary systems.
- Onboard power generation.
Your strategic partner in the Caribbean for marine oils and lubricants
Many Chief Engineers assume that, to access specialized marine oils and lubricants, they must divert to other ports.
In practice, Puerto Rico is a strategic stop where they can restock products and perform maintenance without affecting their itinerary.
Through Royal Petroleum, at American Petroleum we coordinate deliveries directly at the port, ensuring the availability of solutions designed for vessels.
If your vessel requires marine oils and lubricants, our team can assist you with planning and coordinating the supply. Visit our website at americanpetroleumpr.com or contact us at (787) 794-1985.
