Cold Weather Diesel Fuel Additive for Fleets
When temperatures fall, rely on the same proven performance fleet managers trust year-round.
Our OPT Winter Formulation extends the power of OPT-AD, our flagship all-season additive, with advanced Cold Flow Improver (OPT-CFI) technology engineered for today’s ultra-low sulfur diesel, biodiesel, and renewable blends.
Built with advanced polymers and proprietary wax anti-settling chemistry, this robust winter blend defends your fuel from gelling, filter plugging, and cold-weather power loss, while preserving all the performance benefits you count on throughout the year.
The Hidden Costs of Winter Fuel Gelling
Every cold-weather breakdown costs you time, money, and reputation. Without proper cold-flow protection, diesel fuel can thicken and block flow to the engine — especially in northern and high-altitude climates.
Our OPT-Cold Flow Improver (CFI) additive offers the following benefits:
Reducing CFPP (Cold Filter Plugging Point) by up to 25°F or more*
Preventing fuel gelling and wax crystallization
Keeping filters clean and improving fuel flow
Eliminating frozen fuel lines and injector strain
Decreasing emergency service calls
Increasing driver uptime
*Performance may vary by fuel type and blend.
