I moved and changed jobs right prior to doing this OCI; My commute averages 30mph instead of 40mph now, and has been reduced to 40mins one-way. This is the lowest consumption rate I have experienced yet. Started to drive harder, and consumption picked up to something noticeable, and so I went back to my previous driving style to run out the CI. The oil level remained at the top of the dipstick up until around 2,400 miles into the OCI when I did such test. Oil came out darker than I thought it would.
