I installed a catch can right at 14K miles on my '12 coupe. Prior to that I would have to add about a quart of oil every 5K-6K miles. Certainly not an issue.
My car now has 19k miles 5K since the install. Last night I checked the oil and it was full. Right at the bottom of the top hash mark.
My question is that I know the catch can is supposed to prevent oil ingestion, but I should see the oil lower on the engine but in the catch can. No?
Could the catch can actually be preventing the oil from even getting sucked in?

Re: Oil consumption and catch can
Not unless the catch can has a built-in bilge pump to return the oil. Most likely the piston rings are now fully broken in.
