OPT M5 CFI

OPT M5 CFI is a powerful, all-season diesel fuel additive engineered to deliver a 5-point cetane boost while significantly improving cold-weather fuel flow and overall engine performance. Designed for modern high-performance diesel engines, this additive enhances fuel ignition quality, supports cleaner combustion, and provides essential protection against the challenges of low temperatures.

Its advanced Cold Flow Improver (CFI) technology lowers the Cold Filter Plugging Point (CFPP) and Pour Point, helping prevent wax crystallization and fuel gelling that can lead to filter plugging or engine failure in freezing conditions. Whether operating in cold climates or needing year-round reliability, OPT M5 CFI ensures engines start faster, run smoother, and perform better.

Key benefits:

• Cetane increase up to 5 points for faster starts and more efficient combustion

• Improved cold flow properties for reliable winter operation

• Injector cleaning agents to maintain fuel system cleanliness and efficiency

• Enhanced lubricity to reduce wear and extend fuel system life

• Reduced emissions and smoke from more complete combustion

OPT M5 CFI is ideal for diesel-powered vehicles and equipment in both on-road and off-road applications, especially those operating in variable or cold weather conditions. It provides a complete solution to maximize fuel quality, engine response, and operational uptime.
