How Does It Work?

As your engine vents crankcase pressure back through the intake system, oil vapors can coat critical components such as intake valves, intercooler fins, and blower rotors. This buildup can lower your fuel’s octane level and reduce overall efficiency. The J&L Oil Separator prevents this by filtering out the oil vapors before they can enter the intake.

Advanced Filtration System

Equipped with a fine mesh stainless steel filter, the J&L 3.0 Oil Separator effectively traps fine oil vapors, allowing them to condense and collect in the tank. By the time the oil reaches the filter, it is too heavy to pass through, ensuring a cleaner intake system. The knurled tank base allows for easy removal and draining, with an O-ring seal to prevent leaks.

Maintenance & Usage

The separator should be checked after 1,000 miles to assess oil collection. While most vehicles can go 2,500–3,500 miles before needing to be emptied, performance may vary depending on driving conditions and engine modifications.
