Engine Ice

Engine Ice is a powersports coolant brand owned by KOST USA (Cincinnati, OH), best known for its pre-mixed propylene glycol Hi-Performance Coolant/Antifreeze. The brand positions itself for motorcycle, ATV, snowmobile, and watercraft applications where lowered operating temperatures and the non-ethylene-glycol chemistry matter to riders and racers.

The product line is built around a single core chemistry — propylene-glycol-based OAT formulas, phosphate-free, premixed with deionized water for direct-from-the-bottle use. The lower toxicity of propylene glycol vs. ethylene glycol is a primary marketing axis, particularly relevant for garage/track environments where pets, children, or wildlife may have incidental access to spilled or drained coolant.
