Delo® Synthetic Motor Oils and Fluids
We also specialize in supplying synthetic and semi-synthetic motor oils and transmission and drive train fluids that can reduce fuel consumption in your vehicles and lower your operating cost. By analyzing your lubricant needs and recommending the right synthetic oils, Ocean State Oil can help you save 1-3% in fuel consumption - which might not sound like a lot until you think of it in terms of adding 1-3% to your bottom line.
Your Diesel Exhaust Fluid (DEF) Supplier
One important product we supply has become mandatory for 2007 and newer commercial diesel motors: Diesel Exhaust Fluid (DEF), a water-based Urea solution that scrubs nitrogen oxide pollutants from diesel exhaust. These harmful chemicals are central to the depletion of ozone and the formation of harmful smog - and as government regulations have tightened, Ocean State Oil has become the go-to source for DEF and technical know-how to help businesses comply with ever-more stringent diesel engine emission requirements.
So, if you are a business or a government agency that operates fleets of vehicles to deliver people, products, services, or all of the above, Ocean State Oil can help you like no one else in southern New England keep your fleets humming, day after day, year in and year out.
