... back in March at roughly 7,035 miles I had installed a dual oil can catch set up ... today at 7,915 miles I decided to empty both of the cans just to see how much was in there. Was more than I expected, but more unexpected was the fact that the driver side can probably accounted for about 70% of what is in the bag ... 30% from the passenger side can. Weird, I would have thought they would be somewhat even.
