Protect your investment and keep your vehicle running smoothly with regular oil changes as specified by your manufacturer. Oil lubricates, cools, and cleans your engine. An oil and filter change is an easy, affordable way to maintain your vehicle and keep it on the road and running longer.

Regular oil and filter changes are one of the simplest—and most important—ways to protect your boat’s engine and extend its service life. At River City Sports in Bismarck, North Dakota, our Marine Oil & Filter Change Service is performed according to manufacturer specifications to keep your engine running smoothly, efficiently, and reliably throughout the boating season.

Proper engine oil lubricates internal components, reduces heat, and carries away contaminants that can cause premature wear. Routine oil service helps maintain peak performance while preventing costly repairs down the road.

Manufacturer-Specified Maintenance You Can Trust

Our factory-trained marine technicians follow exact service intervals and oil requirements recommended by your engine manufacturer. Using the correct marine-grade oils and approved filters ensures proper lubrication, cooling, and protection—whether your boat is used for fishing, cruising, or watersports.

We inspect oil condition, replace the oil filter, and verify fluid levels to ensure your engine is protected under real-world operating conditions.

Professional Service by Certified Marine Technicians

Unlike automotive oil changes, marine engines operate in demanding environments with higher loads and moisture exposure. Our marine-only service department understands these conditions and performs oil and filter changes with attention to detail that protects seals, components, and internal systems. Each service is completed by certified technicians who know your engine and its requirements.

Preventative Care That Saves You Money

Routine oil and filter changes are a cost-effective form of preventative maintenance. Fresh oil helps reduce friction, regulate operating temperatures, and remove contaminants that can shorten engine life. Staying on schedule not only improves reliability but also helps preserve manufacturer warranties and resale value.
