When the going gets tough, the tough go further #GoFurtherGoFS 


Off-road or on-road, FS is constantly striving to bring you the products and services you need to take your business further. We understand that industry conditions are always changing and our FS Energy Specialists are there to help you meet those challenges every step of the way. Maximizing returns on your energy dollars is how we help take your business just a little further. 

It takes more than fuel and engine oil to keep today’s machinery operating at its best. That’s why we offer a wide range of other products including diesel exhaust fluid (DEF), anti-freeze/coolants, grease and a wide range of lubricants. Not only can your local energy specialists recommend the best products for your needs, they can also recommend the most efficient way to handle and store them.

It takes a variety of oils, fluids, and greases to keep equipment running smoothly. Our line of lubricants delivers ultimate performance and protection, whether you have a long-haul fleet, off-road construction or mining equipment, or need to keep your agricultural machinery running from planting to harvest. 

Our extensive product line includes high-quality engine oils, transmission fluids, gear oils, hydraulic oils, industrial fluids, greases, and antifreeze/coolants. Many of these items are blended at our own lubricants manufacturing facility in Council Bluffs, IA. On top of blending our own oil, we have FS Energy Specialists that help match these products to your equipment and application to bring maximum effectiveness and efficiency. 


Since the 1920s, the FS System has been reliably providing fuels to customers across the Midwest. Today, the FS System is a leading supplier of refined and renewable fuels from the Midwest to the east coast and in Ontario, Canada. Farmers, truckers, construction companies, municipalities and more rely on us to supply their fueling needs. In addition to fuels, our system supplies additized fuels that provide performance beyond conventional fuels. Sales of Dieselex® Gold, the high-performance diesel fuel with origins back to 1952, are growing rapidly as users experience the benefits of using the latest in fuel-additive chemistry. In fact, it was one of the first fuels to be recognized in the Top Tier Diesel Fuel program.
