Cans were installed at 70 Miles. Trip from dealer to house. I will most certainly monitor oil levels with this much discharge at 300 miles. But from what I have read the boosted motors generate more discharge than naturally aspirated. We will see.Sooo, your results are going to be slightly skewed from typical readings because it’s a heritage edition. Hard to say. The fact that it’s an R also adds to it, but you’d need to compare to other results to confirm. The fact that it’s a R AND a heritage really make any quantity from the catch cans hard to quantify as far as readings toward the health of the engine.
