The new design is the 3.0 because it hold 3oz of fluid where the original held a little over 1oz. This oil separator for your 2011, 2012, 2013, 2014, 2015, 2016, and 2017 Ford Mustang 3.7L V6 offers solid and thick billet construction and is easy to install with full directions. It features a new multi-stage filter system designed to collect the finest of vapors and drop them into the easily removable bottom, while allowing clean air to pass through to the intake. J&L OSC put it up against the competition and have the videos to prove it.
During the process of venting crankcase pressure back through your intake track, large amounts of oil, in the form of vapors, intake tube, intake manifold runners and even dilute your gas, lowering its octane level. This happens on all engines and is even worse with forced inducted vehicles (supercharged and turbocharged) as crankcase pressures are increased. To combat this, J&L OSC has developed an oil separator of their own design. Milled from solid billet aluminum this is a rock solid piece. It has a knurled tank base for easy removal to drain the spent oil and an O-ring seal to prevent any leaks.
Filtering consists of a fine mesh stainless steel screen that traps fine oil vapors and releases them once heavy enough to fall. They then pass through a 1/2" thick 1/16th" aluminum honeycomb filter where they grow every larger and then fall into the bottom. By the time the oil gets through the filter it's too heavy to be passed on into the intake. The tank holds 3 oz of fluid, while that may not sound like a lot, you shouldn’t see that much oil in your PCV system. Drain it every 5000-7000 miles and you will never come close to filling it.
