I’ve owned my 2013 mustang gt / 5.0 for 6 months now. In that time I’ve driven it almost 8000 miles. The engine is completely stock other than a JLT oil catch can which was added by the previous owner. Here’s a link to it:
Anyway, when I first bought the car, there was 87k miles on it. I did an oil change at 90k and opened the catch can but it was empty besides maybe 1 or 2 drops. I rinsed it out and reinstalled. This was after 3000 miles. I checked the catch can again today just rolling over 95k (and 5000 miles since last checked catch can) and it had maybe a drop. It was basically empty.
I see videos of people on Youtube reviewing it and when they empty it there is what looks to be 1 or 2 ounces of very dark oil.
Why is my catch can empty after 8000 miles? Is a catch can only needed if your engine is heavily modified? I presume it’s probably a good thing that it’s empty, because it means there isn’t any blowby in my engine? Any input appreciated.
