Talking about this subject. My GT is like yours, but mine has 9K miles. Do you recommend using a catch can on the GT? I've been debating if I should install one. I feel like mine has lost some power. Would the lack of a catch can affect its performance? I live on a small island, so humidity is all year long.Do you live in an extremely high humidity area?
My GT has just over 5K miles. I live in Florida - lots of humidity. When I empty the catch can it is PURE oil - not a watery mixture like in your picture.
When you open your oil fill cap what does the inside of the engine look like? Is it clear oil or do you see a white mixture like in your catch can?
What the oil looks like in my catch can:

Based on your picture, how long did it take to accumulate that much oil?
