I emptied the Apex can today @ 1528 miles, so about 1475 since it was installed.
I drained out 1.2 oz by weight, I found a neat conversion calculator online that converted my weight into fl oz of petroleum based oil to 1.306 fl oz... Pretty amazing for less than 1500 miles of driving
I plan to keep this bottle and record oz caught, mark the level, date, and mileage of each time I dump it... We'll see how much oil is caught over the next year or two...
