How Does It Work?

During the process of venting crankcase pressure back through your intake, oil vapors can accumulate in the intake system, reducing efficiency and lowering fuel octane levels. This issue is even more pronounced in forced induction engines where crankcase pressure is increased. The J&L 3.0 Oil Separator is engineered to combat this problem by effectively capturing oil vapors before they can enter your intake.

Milled from solid billet aluminum, this oil separator is built to last. It features a knurled tank base for easy removal and draining, along with an O-ring seal to prevent leaks. The filtering system consists of a fine mesh stainless steel filter that traps oil vapors, allowing them to condense and collect in the reservoir rather than making their way into your intake.

Maintenance & Performance

The J&L 3.0 Oil Separator holds 3 oz of fluid, which is sufficient for most applications. While you may not see a significant amount of oil accumulation in your PCV system, it's recommended to check the separator after 1,000 miles of driving. Many users can go 2,500-3,500 miles before needing to drain the unit, but every vehicle varies based on driving conditions and engine setup.
