In this review of the J&L Oil Separator Co. 3.0 for 2011-2025 F-150 and '18-'21 Expedition passenger side, the bottom line is simple: it is for owners who want to reduce intake contamination and extend engine life with a compact, user-friendly catch can. The reviewer found the unit effective at trapping oil vapors using a fine mesh stainless steel filter, easy to install using the Plug-N-Play hardware and video instructions, and built for regular service with a knurled drain base and O-ring seal. This review focuses on real-world fit, installation, and ongoing functionality rather than marketing claims.

Key Features

• Fine mesh stainless steel filter: Captures oil vapors and holds them until droplets form and fall back into the tank, reducing intake tract contamination.
• Plug-N-Play installation: Hardware and video instructions simplify fitting to the specified F-150 and Expedition engines for a straightforward DIY job.
• Knurled tank base: Provides a positive grip for easy removal and draining of collected oil without tools.
• O-ring seal: Prevents leaks around the tank base so caught oil stays contained between services.
• Made in the USA: Offers buyer reassurance about manufacturing origin and component quality.

Who It's For

The J&L 3.0 is aimed at owners of 2011-2025 F-150 trucks with 2.7L, 3.5L or 5.0L engines and owners of 2018-2021 Expeditions seeking to reduce intake oil buildup and improve long-term engine health. It suits do-it-yourselfers who want a quick, plug-and-play upgrade and expect periodic emptying of the tank as part of routine maintenance.

This is not a performance tuning device for power gains; buyers looking for horsepower increases or complex baffled systems should look elsewhere. Likewise, owners of vehicles outside the listed model years or engine types should confirm fitment before purchasing.
