I've been reading the benefits of an oil catch can. it's most beneficial for direct injection versus port injection engines. What kind of injection does the 2016 V6 have and would it benefit from a catch can.

it is multiport injection.

because of emission standards, most cars come with an EGR valve..or Exhaust gas re circulation. the EGR recirculates all the gunk and it seems to collects in the intake manifold. this is why sometimes the EGR valve gets blocked up with carbon debris.

a catch can can be beneficial to a non-direct injected engine and a non-turbo car, catching all the gunk from the EGR valve.

 

Not that I own a DI car...but I thought the primary benefit of a catch can was to circumvent the "oily crankcase gases" of the PCV system being dumped into the intake on a DI system where the intake / valves aren't being "washed" continuously with fuel? EGR (exhaust gas recirculation) gases even though below operating temp when redirected to the intake shouldn't be oily? Am I wrong?

 

True. Direct Injection engines can be a real pain in the butt due to the back sides of the intake valves carboning up. There are plenty of YouTube videos showing the effect and all the "spray" fixes that do not really work. Walnut blasting is the only solution.

Not an issue on the RDX. Buy gas with cleaners (usually high test) or use Chevron Techron or Liqui Moly Valve Clean.
