spent 2 days to finish 122 pages, omg. i booked 1.8 MS 2 weeks ago. but was tempted to change 1.5 tc along the reading include change to white colour. However, the conditional maintenace mileage n oil sludge concern have pulled me back to reality. i think 1.8 still the best choice if i am looking for long term usage n less trouble. Hope to join ur guy soon.
