Product Details

Star Brite 312G55 Antifreeze 50 Wintersafe is a non-toxic, propylene glycol-based antifreeze and winterizing solution formulated specifically for protecting marine, RV, and powersports water systems and engines during off-season storage. This 55-gallon drum format is ideal for marinas, dealerships, and fleet operators requiring bulk supply.

The ethanol-free, virgin propylene glycol formula is completely safe for use throughout plumbing systems, water lines, bilge systems, livewells, and raw-water cooled engines. Unlike ethylene glycol products, this formula is non-toxic and safe for use in potable water systems.

Key Features:

  • Non-toxic virgin propylene glycol formula — safe for potable and fresh water systems
  • Ethanol-free formulation prevents degradation of rubber seals and gaskets
  • 50/50 pre-mixed formula — ready to use straight from the drum
  • Protects water systems and engines from freeze damage during winter storage
  • Safe for use with copper, brass, aluminum, and all types of plastic plumbing components
  • Contains advanced corrosion inhibitors to protect all metal engine components and seals
  • Bulk 55-gallon drum for high-volume commercial and fleet applications

Star Brite Antifreeze 50 Wintersafe is the trusted choice for winterizing marine engines, inboard and outboard cooling systems, freshwater tanks, heads, and water heaters. Its broad material compatibility makes it suitable for virtually any system where freeze protection is required during storage.

Good experience!

Awesome, I would recommend them.

Greatly appreciate your prompt shipping

Customer service was nice and kind, still waiting on my return for my second product I purchased. The first purchase was perfect.

It was delivered when it said it was supposed to haven't opened it yet but look forward to seeing it

Ordered 8 11R24.5 tires... Price was good and they shipped out in a day or two. Did not receive in 2 days as promised but that was Fed X's fault not THMotorsports. Would buy from again...
