Delivering Marine Lubricants dockside RI

Engine Oil, Hydraulic Oil & Lubricants for New England's Marine Industry

To facilitate our service to the marine industry, Ocean State Oil has obtained certification from the U.S. Coast Guard for "over water" deliveries in Connecticut, Massachusetts, Rhode Island, and New Hampshire. That means we can park our trucks at the dock and deliver lubricants and fluids directly to active marine vessels - as we do regularly for southern New England fishing boats, tug boats, Coast Guard vessels, ferries, and vessels operated by the National Oceanic and Atmospheric Administration.

We stock a variety of engine oils formulated for use in engines using a variety of marine diesel fuels; environmentally acceptable hydraulic oils that meet VGP requirements; greases for marine applications and more.

High Quality Locomotive and Rail Car Lubricants

High-Quality Locomotive and Rail Car Lubricants

Because many of the bearings in these locomotive types of diesel are manufactured with silver coatings, the lubricants used to protect them must be free of zinc. Zinc is a common component in many standard oils, but it is a chemical enemy to the silver coatings in these locomotive types of diesel. Even small amounts of zinc in the motor's lubricant would prove highly corrosive.

That's why at Ocean State Oil we maintain separate delivery trucks, storage tanks, and pumping and piping systems dedicated exclusively to the sort of zinc-free lubricants required by these locomotive diesel engines.

Diesel Exhaust Fluid DEF for Rail and Marine

Leading the Way in Diesel Exhaust Fluid (DEF) for Rail and Marine

Diesel motors abound in the railroad and marine industries, so government mandates to reduce air pollution in diesel motor exhaust are an on-going concern. And that's one more reason that Ocean State Oil has become an important partner to these industries, as we are a major source for Diesel Exhaust Fluid (DEF), a water-based solution that neutralizes the pollutants in diesel exhaust that contribute to the formation of smog, acid rain, and ozone. Learn more about DEF here.

And, as we do for every other industry and type of business we supply, Ocean State Oil makes our highly-trained technicians available to the railroad and marine businesses to conduct overviews and analyses of why and how a particular business uses our lubricants, fluids, and other products. Our aim is to help those businesses use our products more efficiently and effectively so that their vehicles and machines run better and longer, and their bottom lines stay healthy.
