RL-2 Diesel Ignition Improver 15oz

The RL-2 Diesel Ignition Improver 15oz by REDLINE OIL is engineered for operators and vehicle maintainers who depend on reliable diesel engine performance in tactical and demanding field environments. This cetane-boosting fuel additive addresses a critical performance gap: diesel combustion efficiency under stress, particularly in cold-start conditions or when operating older, high-mileage engines common in military and law enforcement fleets. Whether you're running a generator, tactical vehicle, or mobile command post, fuel quality directly impacts operational readiness and engine longevity.

RL-2 works by elevating the cetane rating of diesel fuel, which measures ignition quality and combustion speed. Higher cetane improves fuel atomization, reduces ignition delay, and promotes cleaner, more complete combustion—resulting in faster cold starts, smoother idle, and reduced injector coking. The 15oz bottle treats approximately 500 gallons of diesel, making it cost-effective for both light tactical vehicles and larger fleet maintenance programs. REDLINE OIL formulations are designed to stabilize fuel, minimize deposits on critical injector components, and protect fuel systems against moisture and microbial growth—essential for equipment stored or deployed in harsh climates.

This additive is particularly valuable for operators maintaining older diesel engines, military surplus vehicles, or systems relying on bulk fuel storage with variable quality standards. Simply add one bottle to the fuel tank before filling; no special equipment or disassembly required. Compatible with all conventional diesel engines—turbocharged, naturally aspirated, emission-controlled, or older mechanical systems. For tactical operations where engine reliability is non-negotiable, RL-2 Diesel Ignition Improver serves as preventive maintenance, reducing downtime and ensuring your power systems respond when it matters most.
