Why Choose Marine-Grade Antifreeze

When it comes to protecting your boat’s engine and onboard systems through the off-season, not all antifreeze is created equal. The antifreeze you pour into your car or lawn mower is not safe or effective for marine use. Here’s why:

Formula Differences

• Mercury Marine Antifreeze: Made with propylene glycol, a non-toxic, biodegradable formula that’s safe for the environment. This formula is designed specifically for marine applications where spills or discharge into the water could occur.
• Automotive Antifreeze: Typically ethylene glycol based, which is toxic to humans, pets, and wildlife. Not safe for the environment and requires careful handling and disposal.

Corrosion Protection

• Mercury Marine: Contains marine-specific inhibitors that prevent corrosion to metals commonly found in boat engines and cooling systems.
• Automotive Antifreeze: Designed for automotive use and may not provide adequate protection for marine-grade components.

Temperature Protection

• Mercury Marine: Ensure burst protection and freeze protection tailored to boating climates.
• Automotive Antifreeze: Does not account for burst protection in plumbing systems, which is critical in marine winterization.

Environmental Responsibility

• Mercury Marine: Non-toxic, safe around docks and marinas, and easy to dispose of responsibly.
• Automotive Antifreeze: Highly toxic, requires special hazardous waste disposal, and can cause severe harm if leaked into waterways.

The Bottom Line

Mercury Marine Antifreeze is the safe, reliable choice for protecting your boat. It’s non-toxic, biodegradable, and engineered for marine systems, unlike regular automotive antifreeze, which is toxic and potentially damaging.
