I have a few answers based on my JLT catch can and my 2013 and 2014 GT experiences.
I have gone almost the entire 10k miles on an oil change and I emptied the catch can twice, once at about 5 and then I emptied it when I changed the oil. Both times the container was a little more than half full...
I GET IT!!! haha :lol:
Also to respond to the thread, I agree the OP needs to fix what he broke, but at a reasonable rate, something along the lines of $1000 would be my guess, maybe a little more. I don't think the dealership pays much more than what the cost is to make and ship the parts...
