When it comes to protecting your fleet’s engines, not all antifreeze products are created equal. With increasing demands on heavy-duty engines, it’s essential to choose a coolant that delivers superior protection, extended service life, and minimal maintenance. That’s where OAT (Organic Acid Technology) antifreeze comes into play.
In this guide, we’ll break down what OAT technology is, why it matters for fleet owners, and how you can upgrade your coolant game with Red OAT Antifreeze Coolant available in 55-gallon drums and 275-gallon totes.
🚚 What Is OAT Technology?
OAT (Organic Acid Technology) is a type of antifreeze formulation that uses organic acid inhibitors instead of traditional inorganic compounds like silicates or phosphates. OAT coolants are designed to offer longer-lasting protection against rust, corrosion, scale buildup, and cavitation—especially important for today’s high-performance, heavy-duty diesel engines.
Unlike traditional green coolants, which typically require a flush and refill every 30,000 to 50,000 miles, OAT coolants can last up to 600,000 miles or more with proper monitoring. This makes them ideal for long-haul trucks, construction equipment, agricultural machinery, and other fleet applications.
