Product Details

Professional Fuel Care for Marine Gasoline Engines

Marine MXO is a commercial-grade, multifunction gasoline fuel treatment engineered specifically for the operating conditions found in marine fuel systems. Built on the proven performance of Mix-I-Go Concentrate, Marine MXO provides enhanced detergency and water-control technology to address the moisture, storage, and fuel stability challenges common to boats and other marine equipment.

Unlike automobiles that consume fuel regularly, boats often spend extended periods sitting between uses while operating in humid environments where fuel degradation and water contamination become greater concerns. Marine MXO helps maintain cleaner fuel systems, preserve fuel quality, and keep engines performing reliably throughout the boating season.

Ideal for recreational boats, fishing boats, personal watercraft, commercial vessels, marinas, and gasoline-powered marine equipment.

Cleans the Entire Fuel System

Marine MXO helps remove carbon, gum, varnish, and injector deposits that can reduce fuel delivery and engine performance.

Cleaner injectors, intake components, and combustion chambers promote smoother engine operation, improved fuel efficiency, and more complete combustion.

Enhanced Water Control for Marine Fuel Systems

Water contamination is one of the most common fuel-related problems encountered in marine environments.

Marine MXO incorporates enhanced water-control technology to help manage moisture in gasoline and ethanol-blended fuels, reducing the likelihood of water-related fuel problems while helping protect injectors and other fuel system components.

Protects Against Ethanol-Related Fuel Problems

Most marine gasoline now contains ethanol, which can contribute to moisture absorption, fuel degradation, and deterioration of certain fuel system materials during storage.

Marine MXO helps stabilize gasoline and ethanol blends while helping protect rubber, plastic, and other fuel system components from the long-term effects associated with ethanol exposure.

Built for Seasonal Storage and Reliable Performance

Marine engines often remain idle for extended periods between outings or throughout the off-season.

Marine MXO helps stabilize stored fuel while maintaining cleaner fuel systems, helping engines start more easily and perform more reliably when it's time to get back on the water.

Professional Performance in a Consumer-Friendly Package

Marine MXO delivers the same commercial-grade fuel treatment technology trusted by fuel professionals, packaged in convenient sizes for recreational boat owners and marine service technicians.

Its concentrated formulation provides economical protection for boats of virtually any size.
